Cannot read property 'flags' of undefined in 3.1.5.

[kleeb]

After updating from 3.1.4 to 3.1.5:

TypeError: Cannot read property 'flags' of undefined

any kind of build

looks like a tslint bug

[mhartington]

Hi there! This appears to be an issue, but there's no information on how to recreate or how to debug this. Could you please provide some more information or a demo in the form of a github repo? Thanks!

[kleeb]

Sure. Its reproducible on any project, even starters: ionic start myApp tabs

and run prod build

npm run ionic:build --prod

on our project it fails even on the dev one. Hope that helps

[mugavri]

It happens to me as well, I went back to version 3.1.0 And it works for me

[kleeb]

For my project 3.1.4 is stable. On 3.1.5 and 3.1.6 it occurs.

[Khalid-Nowaf]

I have the same problem here, I just update to 3.1.6, so I can fix the bug with WebSockets. so now I have to choose "Live reload" vs "build --prod" ^^;

[mhartington]

Not able to reproduce this at all. What version of node are you using?

[Khalid-Nowaf]

node: v6.11.4 typescript: 2.4.2 ionic/app-scripts: 3.1.4 ionic-angular: 3.9.2, ionic-native/core: 4.4.0

[kleeb]

Node v8.9.1 npm 5.5.1

[jwelmac]

Having the same problem on my end ionic/app-scripts: 3.1.4 works well anything after throws the above error.

Node v8.9.3 npm 5.5.1

[tgensol]

Having the error too with app-script@3.1.7. Going back to 3.1.4 is solving the issue

[mhartington]

Hi folks! I have not been able to replicate this using the latest version of app-scripts, the cli, and LTS of node. Im Going to close this for now. If anyone can please provide a sample project that has this error, I will take a look.

[geo242]

I am having the same issue with 3.1.7. Going back to 3.1.6 works for me.

[kensodemann]

Can someone post a GitHub repo for a project that exhibits this? I have several test projects, a couple of personal projects, and a training lab project, all using 3.1.7 and none of them exhibit this issue, so having a test project to dig into would be helpful.

[kleeb]

Here you go https://github.com/kleeb/issue-1347

after cloning npm install && npm run ionic:build --prod

    @ionic/cli-utils  : 1.18.0
    ionic (Ionic CLI) : 3.18.0

local packages:

    @ionic/app-scripts : 3.1.7
    Ionic Framework    : ionic-angular 3.9.2

System:

    Node : v8.9.1
    npm  : 5.5.1 
    OS   : macOS Sierra

Misc:

    backend : legacy

[kensodemann]

Thank-you. I was able to duplicate the issue using that repo. Reopening so we can have a look. cc @mhartington

[jwelmac]

I believe the issue may have to do with the upgrade of the @angular-devkit/build-optimizer from 0.0.33 to 0.0.35 and/or its dependencies

That's the only major change I was able to pick out of the commit changes since 3.1.4

[mhartington]

The main issue here seems to be the version of the ng-cli you have installed for the tests. Please run

npm install @angular/cli@latest --save-dev

[kleeb]

@mhartington updating @angular/cli hasn't solved this issue for me

[tgensol]

Same for me, updating the angular/cli is not working

cli packages: (/usr/local/lib/node_modules)

@ionic/cli-utils  : 1.19.0
ionic (Ionic CLI) : 3.19.0

global packages:

cordova (Cordova CLI) : 8.0.0 

local packages:

@ionic/app-scripts : 3.1.7
Cordova Platforms  : android 6.4.0 ios 4.5.4
Ionic Framework    : ionic-angular 3.9.2

Environment Variables:

ANDROID_HOME : /usr/local/opt/Android

Misc:

[jwelmac]

Same here.

What I did realize though is that the @angular-devkit/build-optimizer@>0.0.35 lists typescript@~2.6.1 as a dependency. When this was installed as a direct dependency that error message was gone for me and ngc was able to complete.

Though I did throw another error later in the build process but that may be due to my code.

[mhartington]

Ok, looks like I was too quick. Digging into this

[geo242]

I had a strange experience... I downgraded to 3.1.6 and then installed 3.1.7 and it started working. Very strange.

[mhartington]

For those having this issue, do you have ionic listed in your package.json?

[kleeb]

In devDependencies - yes I posted package.json in this thread

[mhartington]

@kleeb can your uninstall that and try to build

npm uninstall ionic --save

[tgensol]

I only have ionic-angular, not ionic on my side

[kleeb]

@mhartington removed ionic, cleaned & rebuilt the project the result is the same: Cannot read property 'flags' of undefined

[kensodemann]

Based on experimentation by me, @mhartington, and @danbucholtz, I did the following and it worked for me:

1. cloned the sample repo https://github.com/kleeb/issue-1347
2. make the following changes to the package.json file before doing an npm i

The key to this seems to have been the removal of the @angular/cli package. I only removed gulp because there was no gulpfile.

[kleeb]

I do confirm! Removing @angular/cli is doing its job.

Thanks @kensodemann @mhartington @danbucholtz

[tgensol]

I removed the @angular/cli, and I still have the issue on my side

[kleeb]

@tgensol post your package.json

[kleeb]

you are missing "ionic": "3.19.0" in devDependencies

[tgensol]

Still got the issue even with the "ionic": "3.19.0" in devDependencies

[kleeb]

I would downgrade all @angular/* deps to 5.0.0

[tgensol]

It doesn't work either. I will downgrade app-scripts to 3.1.4

[kensodemann]

@tgensol - after removing @angular/cli did you remove your node_modules directory and then do a complete reinstall of the NPM packages? Sometimes that is necessary. I often do that just to be safe.

FWIW, in my tests, I had used both Angular 5.0.0 and 5.1.3, and it worked in each case. My diff posted above is just what the minimal changes I made to @kleeb's package.json and really the @angular/cli was the key in that case.

In your cases, there are so many deps and plug-ins that I don't even what to guess at what could be triggering the issue, but you could try something like:

1. ionic start tabs test-1347
2. npm i
3. ionic build --prod
4. add your deps one dep at a time until stuff breaks

[JustinPierce]

I've found that @ionic/app-scripts and @angular/cli can still coexist, but the order in which you install them matters. I've only had success by installing @angular/app-scripts first. Depending on the state of your package-lock.json, you may need to try the nuclear option:

1. Delete package-lock.json and node_modules.
2. Remove @angular/cli from package.json. Leave @ionic/app-scripts@3.1.7 in place.
3. npm install
4. npm install @angular/cli@latest --save-dev
5. ionic build --prod
6. Hopefully do a happy dance.

Confirmed working now!

Hey Guys, Is there any way to fix this issue internally and resolve this discrepancy? Currently, I cant just put all my dependencies in my package.json and know that I will have a successful build when it goes to CI/CD. Also by trying to install @angular/cli in the postinstall script Ionic Pro throws an error saying sh: 1: ionic-app-scripts: not found

Reverting to 3.1.4

[EugeneSnihovsky]

Does anyone has workaround?

After updating my private app to ionic 3.9.2 / angular 5.0.0 / @ionic/app-scripts 3.1.7 it throws an error on ngc command when I build app with --prod or --aot flag. I am not using angular cli in this project but it installed globaly (v.1.6.4).

[10:39:21]  ngc started ...

Dev livereload server and dev build works fine.

If I downgrade @ionic/app-scripts to 3.1.4 - prod version builds fine, but dev livereload server throws an error

command npm run build:ios fails on ionic-app-scripts 3.1.7

command npm start fails on ionic-app-scripts 3.1.4 on each livereload

[kleeb]

try to fix typescript version to the exact "2.4.2"

[EugeneSnihovsky]

@kleeb didn't help. Same error Cannot read property 'flags' of undefined

Update: got workaround with ionic-app-scripts 3.1.4 and npm i -D -E ws@3.3.2. Now build with prod and aot works and livereload server don't crash on each reload.

[kleeb]

but have you removed node_modules are rerun npm i ?

[EugeneSnihovsky]

Yes. Every time I do fresh install without node_modules folder in project
