角度cli ng服务错误

Question

angular-cli used to work perfectly, but now I don't know why when creating a new project it doesn't run the server.

I tried reinstalling angular-cli.

I create a new app with ng new app . I navigate into the /app/ path, run ng serve and I get:

No errors

Answer 1

From an Angular CLI developer :

This problem arises from a recent update in a external dependency and it's not fixable without a CLI release right now.

He also confirmed that the workaround is to install the dependency at version 2.0.0-rc.0:

npm install extract-text-webpack-plugin@2.0.0-rc.0 --save-dev
