[dejobo]

so do we. same error!

[MehranJanfeshan]

@dejobo @yeah007 I have downgraded ng CLI to 6.0.8 and it works for me.

Hi @yeah007 ,

Are you sure you are running ng version inside your project? We do not have nor publish an ember-cli folder anymore, since 6.0.0, so I'm pretty sure this is a version mismatch and something is not right in your node_modules.

I'm going to close this issue as not a bug. If you cannot figure out the error, please file a new issue and share your package.json and a proper ng version run from the project directory (we want to know what the local version is).

@hansl same happend to me :(
I've tryed ng version

Same error when run the command: ng build --prod --aot

[Aenigma]

I got this error and it seems to stem from the fact that I have an older version of ng cli on the project vs the version of ng cli installed globally.

I was able to fix this by updating the local ng cli version manually and then migrating it by running:

npm install --save-dev @angular/[email protected]
yarn add -D @angular/[email protected] # if you use yarn

ng update @angular/cli --migrate-only --from=1.7.4

For CI builds, it may be worthwhile to invoke ./node_modules/.bin/ng instead of installing @angular/cli globally.

[azulay7]

@Aenigma
ng update @angular/cli --migrate-only --from=1.7.4 didn't work .
actually ng -v gives the same error.

[marcosrodriigues]

same for me...include ng -v gives the error.

npm -v
6.2.0

node -v
v10.7.0

the code

ng update @angular/cli --migrate-only --from=1.7.4
isn't work, I've got this error:

[axacheng]

It's certainly related to angular-cli latest release - 6.1.0 and 6.1.1 yesterday.

My workaround was downgraded angular-cli to 6.0.8.

$ ng serve

@axacheng it works for me.

My problem was a little bit difference, I've got 'angular.json' error after execute these steps.
To solution the problem, I've execute the followings commands at terminal:

1 - npm un @angular/[email protected] -g --save
2 - npm i @angular/[email protected] -g --save

After that, I've got something like this:

Local workspace file ('angular.json') could not be found.
Error: Local workspace file ('angular.json') could not be found.

So I've execute:

ng update @angular/cli --migrate-only --from=1.7.4

and ng serve works!

[yeah007]

Yes, it works after revert to 6.0.8. It seems a issue of 6.1.0.

[ahmed3eraqi]

@axacheng thank you very much it's worked with me

[csotomon]

6.1.1 keep this error

[Aenigma]

@azulay7 I updated my previous comment. I failed to mention, because I didn't realize it was significant, that I first updated Angular CLI manually and then I ran ng update. This approach should let you safely upgrade to the latest version of Angular CLI.

npm install --save-dev @angular/[email protected]
# now, ng version should work
ng update @angular/cli --migrate-only --from=1.7.4

[azulay7]

thank @Aenigma @marcosrodriigues. works for me!

[jpCamino]

@marcosrodriigues thanks that worked

[ScarUgo]

Issue has been fixed in v 6.1.4
