Using invalid environment causes error in build (was "ERROR in Cannot read property 'length' of undefined") #5053

Closed elvisbegovic closed 6 years ago

elvisbegovic commented 7 years ago

(on existing project, on windows10) After updating :

  1. cli 31 to rc0
  2. angular packages to rc1
  3. typescript to 2.1.6

I get this insignifiant message error when runningng serve orng build:

Cannot read property 'length' of undefined TypeError: Cannot read property 'length' of undefined

What does this mean ?

deebloo commented 7 years ago

@istiti can you fill out the issue template and give the steps to reproduce? What version of the cli are you updating from?

elvisbegovic commented 7 years ago

@deebloo please apologize see point 1 again. I have no additional info:

dmytro-y-dev commented 7 years ago

@istiti Did you use ng new to create the project?

If so, make sure that you kept all original arrays in .angular-cli.json configuration like assets, styles and scripts. I received mistake as you do, because I removed assets option from .angular-cli.json.

elvisbegovic commented 7 years ago

@metamaker no I don't use ng new I have assets styles and scripts as array. I try on exisiting project running angular 2.4.8 ith cli31 to update to cli-rc0 and angular rc1 !

dmytro-y-dev commented 7 years ago

Provide your .angular-cli.json, please.

elvisbegovic commented 7 years ago

https://gist.github.com/istiti/e544744f16480829416e62b32167051e

ps: when running ng new test --ng4 it works... but I want get working again my existing project

dmytro-y-dev commented 7 years ago

Your .angular-cli.json looks ok, not sure what is wrong. Maybe someone else will be able to help you ;) .

elvisbegovic commented 7 years ago

additional info : I tried in green project "ng new mynewproject --ng4" it work well, it run!

then move all my old /app folder to this new one and I get same error !

apparently the issue is in my code/module ... My project is relativly big I can't remove module by module :(

how achieve this ? can I get more signifiant message error

thanks

hansl commented 7 years ago

This is a real issue and we will look at it.

elvisbegovic commented 7 years ago

Additionals infos: Yes of course I always use Renderer and template in my project.. but need more signifiant message error to achieve this properlly.

Thanks, actually can't move...

Cc @hansl

hansl commented 7 years ago

@isiti can you provide a repository or some sort of code sample that we could use to reproduce? Maybe your package.json might be enough, if you're okay to share that.

elvisbegovic commented 7 years ago

Will do it tomorrow at 7AM (UTC +1)

Thanks coz can't move (actually blocked)

@Hansl

trentmswanson commented 7 years ago

I was experiencing the same issue here and after I rolled typescript back from 2.2.1 to 2.0.10 that seemed to fix it.

elvisbegovic commented 7 years ago

@hansl here you are https://gist.github.com/istiti/f97eb83c6d18fd1d23965e4a3325033e

@trentmswanson FYI after passing from 2.1.6 to 2.0.10 I get this error

then when I update typescript from 2.0.10 to 2.2.1 I get same error as in 2.1.6

rdesimone commented 7 years ago

The strange thing here: the project with angular-cli rc.0 was working fine till executing the first ng build --target=production (maybe just a coincidence). Since then the project is broken. ng serve gives the same error now.

When I setup a new project, it is possible to build.

I removed and reinstalled angular-cli like documented (including node_modules) - the same. Also downgraded Typescript to 2.0.0 like the default for a blank project and took all possible settings of a blank project.

rdesimone commented 7 years ago

Checking out from the repository into a new directory and running npm install fixed the issue - the files are the same. The project in the original directory became suddenly unusable - was not able to find out the reason.

elvisbegovic commented 7 years ago

As said : I putt in new green cli --ng4 project whole my /app folder and same issue

moniuch commented 7 years ago

Apart from the lack of a descriptive message (which is the main focus for this issue), should anyone run into this case, don't panic - chances are that it's just a temporary glitch. I ran into this situation twice and it looked like a local problem with syncing files. The second incident of mine was a bit more clear to me - it followed a git pull. Waiting ca 1 minute and rebooting ng serve cured the app and restored its running state.

FWIW: Since this is ng serve reboot that helps, I would recommend to look closer at the angular-cli.json file - perhaps into the apps.assets item which has been made a mandatory array if I am correct (meaning it does not accept a single string anymore).

elvisbegovic commented 7 years ago

additional info: same behavior with angular rc2

elvisbegovic commented 7 years ago

additional info

with this conf. my project works/compile fine with typescript 2.1.6 here's my working package.json: 

@angular/cli: 1.0.0-rc.0

@angular/platform-browser-dynamic: 2.4.9
@angular/router: 3.4.9
@angular/cli: 1.0.0-rc.0
@angular/compiler-cli: 2.4.9

BUT it breaks

when I add these lines to my package.json, I getlength undefined:

moosetraveller commented 7 years ago

Probably not the same cause but we had the same error (Cannot read property 'length' of undefined) when we accidentally deleted environment.prod.ts during a refactoring process. Restoring this file solved our problem.

henritoivar commented 7 years ago

@moosetraveller Thanks a lot. This actually happened to be the issue. On our staging server we had no environment file set up.

elvisbegovic commented 7 years ago

nop, it's not same cause... I have this file under src/environments/environments.prod.ts

cc @moosetraveller

cgebe commented 7 years ago

Issue was resolved by adding an environment.prod.ts file as stated by @moosetraveller. Thanks! Though, an error message more appropriate to the cause would be much appreciated.

elvisbegovic commented 7 years ago

donno why to me it isn't resolved :S and I have this file inside my project :s

cgebe commented 7 years ago

@istiti

content of my environment.prod.ts:

export const environment = {
  production: true,
  silent: false
};

Maybe, there are additional causes for this issue. CLI error message is misleading in this case.

ctaepper commented 7 years ago

i had the same problem, other cause: one of my dependencies referenced a .d.ts file which was simply not there (https://github.com/swimlane/ngx-charts/blob/master/release/d3.js#L1) if i run ng build without aot and prod flag, it would try to lookup that file which resultet in that error

anyway, now i am not sure, if i am doing it wrong, or if @swimlane has an error here...

moosetraveller commented 7 years ago

@istiti there is a Stackoverflow (http://stackoverflow.com/a/41231897/42659) answer pointing out that the source folder may not be found/readable

calebkiage commented 7 years ago

I think in many cases this issue is caused when typescript tries to process a file that doesn't exist. In one of my projects it was a missing .d.ts file. In another it was a missing environment ts file. Adding a console.log(fileName) in the beginning of the createSourceFile function at node_modules/typescript/lib/typescript.js helped me pinpoint the specific file. Remember to remove the changes or just reinstall your node_modules.

elvisbegovic commented 7 years ago

guys thanks to solve this bug to me ! i effectivly had this /// reference to .d.ts file not exist anymore in angular4 !

one of my team member import this file accidently, he don't remember why he did this, this file was available before in ng 2.x (i think) <reference path="../../../../../node_modules/@angular/core/src/facade/async.d.ts"/>

in another file he imported isPresent from "@angular/core/src/facade/lang" but this isPresent is now in this path "@angular/core/typings/src/facade/lang";

ps: i still not understand what is this isPresent but good no more this insignifiant error1

I let this issue open until a team memeber improve message error terminal cc @ctaepper @calebkiage , @hansl

@ChrisTarasovs can you read this tread please because as said you can find error using this adivce

Adding a console.log(fileName) in the beginning of the createSourceFile function at node_modules/typescript/lib/typescript.js helped me pinpoint the specific file.

ChrisTarasovs commented 7 years ago

Thank you @istiti I did read and tried several time what was said. So above function createSourceFile(fileName, sourceText, languageVersion, setParentNodes, scriptKind) { I have added console.log(fileName); on line 8724 , right above the function and tried inside the function also.

but than I run ng serve and I get the same issue as I get just the same error. Don't seem to understand how you can get the ouput of console.log if that is shown in the browser but I can even load the page?

Currently I got fallbackLoader option has been deprecated - replace with "fallback" loader option has been deprecated - replace with "use" fallbackLoader option has been deprecated - replace with "fallback" loader option has been deprecated - replace with "use" fallbackLoader option has been deprecated - replace with "fallback" loader option has been deprecated - replace with "use" fallbackLoader option has been deprecated - replace with "fallback" loader option has been deprecated - replace with "use" Cannot read property 'length' of undefined TypeError: Cannot read property 'length' of undefined at createSourceFile (C:\Users\ctarasovs\AppData\Roaming\npm\node_modules\ang ular-cli\node_modules\typescript\lib\typescript.js:8980:109) at parseSourceFileWorker (C:\Users\ctarasovs\AppData\Roaming\npm\node_module s\angular-cli\node_modules\typescript\lib\typescript.js:8940:26) at Object.parseSourceFile (C:\Users\ctarasovs\AppData\Roaming\npm\node_modul es\angular-cli\node_modules\typescript\lib\typescript.js:8899:26) at Object.createSourceFile (C:\Users\ctarasovs\AppData\Roaming\npm\node_modu les\angular-cli\node_modules\typescript\lib\typescript.js:8727:29) .....

@ChrisTarasovs your console.log in this file input in your command line not browser what's your ts version ? give your package.json

@istiti Just to let you know that I am trying this on OS and Win system On OS I have setup with @angular 2.4.8 and on Win I have setup the latest 2.4.9

Here is the exact steps I tried

  1. Install node latest v7
  2. Install angular cli > npm install -g @angular/cli
  3. Open CMD and via CMD navigate to Desktop > cd Desktop
  4. Create an angular project via angular CLI > ng new testNg
  5. Navigate to project > cd testing
  6. Run ng serve to launch > ng serve ( response all good, page loaded)
  7. Navigate to app to add the code from github > cd src/app
  8. Clone from github using SSH into the app folder > git clone git@github.com:akserg/ng2-dnd.git
  9. Run ng server to launch > ng serve ( errors)
  10. Found out I had a missing typescript, so install typescript > npm install typescript –save 10.2 Added on type \Testing\node_modules\typescript\lib\typescript.js on line 8735 console.log(fileName); - that is inside the createSourceFile function.
  11. Found out that rxjs not installed > npm install rxjs –save
  12. Ng serve> still error
  13. Ng build > still error

Currently with the files above here is my win setup also >npm --version 4.1.2

>ng --version angular-cli: 1.0.0-beta.28.3 node: 7.7.1 os: win32 x64 @angular/common: 2.4.9 @angular/compiler: 2.4.9 @angular/core: 2.4.9 @angular/forms: 2.4.9 @angular/http: 2.4.9 @angular/platform-browser: 2.4.9 @angular/platform-browser-dynamic: 2.4.9 @angular/router: 3.4.9 @angular/compiler-cli: 2.4.9

@ChrisTarasovs I think the lib you are trying to clone

ChrisTarasovs commented 7 years ago

and you can't juste clone everything inside src/app and expect it to works but at-least i expect it to build or compile. Using my json file did u have success to setup ?

augusto-elevenapp commented 7 years ago

anyone solved this?

I'm still getting this error. On my computer it works fine, but when I push it to Heroku, I gives this error. I can't use the approach to console.log the fileName on typescript package because heroku always installs everything again. It worked fine until my last build to heroku (a week ago)

augusto-elevenapp commented 7 years ago

sorry, my bad! after last build, I had installed typings packages, and not saved in typings.json. typescript could not find the definitions

wolkesson commented 7 years ago

This error seem to have different reasons and different solutions. In my case I had a reference ///<reference path="..\..\..\typings\globals\google.maps\index.d.ts" /> pointing to a file that did not exist.

I fixed this by making sure my main property pointed to my main.ts relative to the root property. Since my root is set to src and main.ts is at src/app/main.ts I changed my main property to app/main.ts.

@brettatoms, thanks, your solution did the work

jwelmac commented 7 years ago

@brettatoms. Thanks your solution worked for me with an Ionic 2 project.

dherges commented 7 years ago

Regarding the "missing d.t.s file" issue: can this be reported by Angular CLI and printed to console? Is it possible or should the warning be printed by tsc?

lawmbass commented 7 years ago

Thanks a lot @brettatoms that seemed to fix my problem.

jameslieu commented 7 years ago

Having looked at my .angular-cli.json file.

I noticed that the environment.prod.ts and environment.dev.ts files were missing. Adding these files in has fixed this for me.

"environmentSource": "environments/environment.ts",
"environments": {
    "dev": "environments/environment.dev.ts",
    "prod": "environments/environment.prod.ts"
}
