Error: dryRunSink.commit(...).ignoreElements(...).concat is not a function

[rilwans]

Just Upgraded to Angular CLI: 1.6.4

each time I run ng new I get this error

Error: dryRunSink.commit(...).ignoreElements(...).concat is not a function dryRunSink.commit(...).ignoreElements(...).concat is not a function

[csmrkid]

by adding "@angular-devkit/schematics":"0.0.42", "@angular-devkit/core": "0.0.23" , then run "npm install" work for me

[scott-engemann]

I'm currently working on a project that has existed for 6+ months. We encountered this issue with Angular CLI when our new developers attempted to set up their dev environments and run basic Angular CLI commands. I get the following error when we attempt to generate a component:

$ ng g c some-component
Error: dryRunSink.commit(...).ignoreElements is not a function
dryRunSink.commit(...).ignoreElements is not a function

So far the only thing that has worked was downgrading to @angluar/cli to v 1.3.2. I also encountered an error regarding rxjs but that is resolved by upgrading rxjs to version 5.5.2. Here is our package.json

"dependencies": {

[ngochibamu]

npm install @angular-devkit/schematics@0.0.45 @angular/cli --no-save

This is the vodoo that worked!

[Deilan]

Nope, fixed not completely. Even after upgrading @angular-devkits and purging node_modules, package.lock.json and yarn.lock.

$ ng generate service qwe
Error: dryRunSink.commit(...).ignoreElements is not a function
dryRunSink.commit(...).ignoreElements is not a function

I also confirm that downgrading to @angular/cli to 1.3.2 is the only completely working solution as of now.

[Wael3bbas]

It works for me on Angular CLI: 1.6.4 Node: 6.10.3 the common thing I can see on users had this issue is node version greater than 8 or less than 6.9

[j-Cis]

I have the same problem and installing these libraries

    "@angular-devkit/build-optimizer": "^0.0.38",
    "@angular-devkit/core": "^0.0.25",
    "@angular-devkit/schematics": "^0.0.48",

does not help, someone has already found a bug-fix?

[hugocaldeira]

Solved! Add to package.json inside devDependencies

"@angular-devkit/schematics": "0.0.43",
"@angular-devkit/core": "0.0.23"

Save file npm install

[Dok11]

@hugocaldeira I dont think. This way did not help me.

[Wael3bbas]

Also, this works for me

npm i @angular-devkit/schematics@0.0.45 @angular/cli --no-save

[abalazsics]

@mendhak's solution worked for me Angular CLI: 1.6.2 Node: 9.3.0 OS: darwin x64

[onedotover]

I just upgraded Angular CLI and ran into this issue generating components. I noticed I didn't get this issue when I created a new project.

The fix for me was to remove the node_modules folder and package-lock.json. Then re-install node modules using npm install

[ssokurenko]

That helped me:

• Removed node_modules and re-installed by npm install
• Installed npm i --save-dev @angular-devkit/core

[foote-Greg]

@ssokurenko solution worked for me after the other solutions failed to work....

[intellix]

same thing for me on 1.6.5 it seems. Deleted node_modules and package-lock.json and reinstalled. Now it's all good

[chandurams]

Thanks @gurgelv its working.

[morismael]

Thanks @ssokurenko . Your solution worked for me (CLI 1.6.5)!

[Siafu]

Why is this issue closed? I can't seem to get rid of it at all.

[topikus]

Thanks @ssokurenko . Your solution worked for me (CLI 1.6.5)!

[markus-heinisch]

Sorry, still get same error! I have deleted my node_modules folder and reinstalled my dependencies. What can I do now? Thanks, Markus

[Justin-MacIntosh]

The workaround in the commit by @jgarciao was the only thing that worked for me.

EDIT: for clarity, needed to delete node-modules folder and npm install after making the changes

[marc101101]

still same problem. Tried @jgarciao 's solution - not working for me :(

My global CLI version is 1.6.5

None of the solutions mentioned above are working for me.

Shouldn't this issue be opened again?

[Justin-MacIntosh]

@marc101101 Did you delete the node-modules folder, and npm install after making the fix in the commit?

[kchiragowni]

@Justin-MacIntosh deleting node_modules and ran npm install fixed my issue. Thanks

[ilDon]

The solution suggested by @jgarciao does not work for me, even after deleting all node modules. I also tried installing globally the packages, but still getting the same error. Any idea?

[Dok11]

@ghego1 check versions of your packages

[MartinNuc]

Deleting yarn.lock and running yarn install again helped me.

[ilDon]

@MartinNuc right! So the trick when using yarn is to first update package.json as described by @jgarciao, delete yarn.lock, and then run yarn install.

[FreezeSoul]

same error, thk for up

[glebmachine]

I have fixed it by install proper rxjs version: yarn add rxjs@5.5.2

But, my error was

dryRunSink.commit(...).ignoreElements is not a function

[olufemioyedepo]

@mendhak solution worked for me!

[RonakR]

I have the proper rxjs version (5.5.2) along with all the proper version above and I still see the same error.

Error: dryRunSink.commit(...).ignoreElements is not a function
dryRunSink.commit(...).ignoreElements is not a function

[markus-heinisch]

Hi, has someone tried to solve the problem with angular-cli v1.7.0-beta.1? I'm referring to:

Error: dryRunSink.commit(...).ignoreElements is not a function
dryRunSink.commit(...).ignoreElements is not a function

[andreimcristof]

have the exact same issue right now when using ng generate component

[olufemioyedepo]

@andreimcristof try this npm install @angular-devkit/schematics@0.0.45 @angular/cli --no-save

[yogibimbi]

seems updating to

"@angular-devkit/schematics":"0.0.51",
"@angular-devkit/core": "0.0.28",

and deleting node_modules + npm install might have done the trick for me. But I also updated some other versions of ng libraries that were warned about after previous installs, so I can't say with absolute certainty that the above two lines are what pushed it over the top. So, at least ng g service bla now works.

[NickToony]

Also experiencing this issue, tried various fixes suggested here. I don't think this issue should be closed.

Error:

ng g component name

EDIT: My problem was with using rxjs 5.5.2. I changed to the following dev dependencies:

"@angular-devkit/core": "0.0.28",
"@angular-devkit/schematics": "0.0.51",

and updated to rxjs 5.5.6

"rxjs": "5.5.6",

and then deleted my node_modules and package-lock, then npm install. Hope this helps someone.

[titusfx]

@mendhak solution didn't work for me. I got a new one after that:

Error: Path "/app/app.module.ts" does not exist. Path "/app/app.module.ts" does not exist.

I don't think this issue should be closed.

[jorgeso]

I've tried every single solution offered here and nothing works. This is ridiculous. Why is this issue closed?

[glebmachine]

Try using this:

yarn add --dev @angular-devkit/core@^0.0.28 yarn add rxjs@^5.5.2 rm -rf yarn.lock; rm -rf node_modules; yarn;

This error cause in angular-devkit/core. There was undefined observable method. Yesterday it was take me about 3 hours to investigate and fix that. I hope it will help

[markus-heinisch]

I have found a solution for my project: I have deleted my node_modules folder, checked my package.json and installed my dependencies in several steps:

This was closed as no longer an issue, but I just installed @angular/cli (using npm install -g @angular/cli@latest) and cannot create a new app. Is 1.6.5 still pulling in the old dependency? I was under the impression, per https://github.com/angular/angular-cli/issues/9283#issuecomment-358937066 that this was no longer an issue.

Please reopen, still an issue

[Brocco]

We the "CLI Team" would like to apologize for the confusion.

Status

This issue has been resolved in version 1.6.6.

Updating

The steps to update your environment to the latest version containing the fix:

npm uninstall -g @angular/cli
npm cache clean
# if npm version is > 5 then use `npm cache verify` to avoid errors (or to avoid using --force)
npm install -g @angular/cli@latest

rm -rf node_modules dist # use rmdir /S/Q node_modules dist in Windows Command Prompt; use rm -r -fo node_modules,dist in Windows PowerShell
npm install --save-dev @angular/cli@latest
npm install

Explanation

The issue of [rxjs operator] is not a function is a result of the migration of the devkit repo to using "pipeable" (formerly "lettable") operators instead of the prototype patching approach that the Angular CLI was using prior to release 1.6.6 (which was just released). The commit which fixed it is here.

The issue is that the CLI was using operators that were not imported and relied on them being on the Observable object. When the devkit was updated it removed this function and the bug in the CLI was exposed. The latest version of the CLI is now using pipeable operators and therefore importing all of the operators needed to work with observables, so this issue has been resolved.

Thank you for your patience and for contributing by reporting this issue.
