angular-cli: Web cannot run after update angular cli to 6.1.0

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

so do we. same error!

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

@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/cli@6.1.1
# now, ng version should work
ng update @angular/cli --migrate-only --from=1.7.4

@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/cli@6.1.0 -g --save 2 - npm i @angular/cli@6.0.8 -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!

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

6.1.1 keep this error

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/cli@6.1.1
yarn add -D @angular/cli@6.1.1 # 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.

@hansl same happend to me 😦 I’ve tryed ng version same error:
