Desired functionality

it says it passes linting, but then throws an error, too

Mention any other details that might be useful

Thats an rxjs issue when there are multiple versions of rxjs mainly 6.3.0 - 6.3.1 with 6.2.X https://github.com/ReactiveX/rxjs/issues/4077

This should have been fixed in RXJS 6.3.2. However, if you have rxjs as a transitive dependency between 6.3.0 amd 6.3.1 it will still fail.

Couple of things you might want to try, remove the lock and node_modules and try again, Or update the devkit and angular-cli packages to the latest versions as we pinned down the rxjs package.

If the issue still happends when not having any transitive dependency between 6.3.0 and 6.3.1, we might need to open a new issue with rxjs.

[johnpapa]

thanks. tried rm -rf node_modules package-lock.json and re ran npm i and it did not work.

i already updated everything reported by ng update.

i just manually updated from 0.6.0 to "@angular-devkit/build-angular": "~0.8.1" and then the error goes away when i run ng lint --fix

Perhaps we can have a clearer error with a suggestion?

Or perhaps we can have ng update also check the devkit? (because it didnt tell me anything about it)

Opened a new issue with rxjs https://github.com/ReactiveX/rxjs/issues/4135

Same here http://prntscr.com/kvwkk2

[cmckni3]

For me, this happened when I updated RxJS. My package.json specifies ^6.0.0 but @angular-devkit/architect, @angular-devkit/schematics, @schematics/update, and @angular/cli all wanted ~6.2.0. I ended up with RxJS 6.2.2 and RxJS 6.3.2 installed in my project.

[davl3232]

@cmckni3 did you manage to work around this?

[davl3232]

In my case ionic stops working. Ionic internally runs ng run app:serve --host=0.0.0.0 --port=8100.

[cmckni3]

@davl3232 yes, I changed RxJS in my package.json to ~6.2.2.

[peterramaldes]

If I use version 6.2.2 I have no problem with lint.

Does anyone know why the updated version has this problem?

[alan-agius4]

This has been fixed with RXJS 6.3.3
