After install I am getting this error.
npm -v
- 6.5.0
node -v
- v9.10.1
Angular CLI
- 7.1.4
The problem was caused by a typo with regards to the version number of webpack-dev-server. This has been fixed by the webpack-dev-server team, but the angular team is working on releasing an updated version of the @angular-devkit/build-angular, which includes a reference to webpack-dev-server.
The fix may be released on Wednesday January 9, 2019, according to this post:
npm installin the project folder and all of the dependencies mentioned in the package.json will be installed.
