I faced the same issue Today. This is how I fixed it:

1: Updated Angular Cli Globally by running: npm update -g @angular/cli

2: Remove node_modules folder from the project and then check the Angular Cli version by hitting ng -v like this:

3: Check your project’s package.json file, if the version you checked earlier are same then goto your cmd and run npm install if not then change the @angular/cli version to the version you checked and then run npm install

IT SHOULD START WORKING NOW…

Note: The above solution is valid and if it doesn’t work then you can follow my steps or you can directly use steps mentioned by me. Its a permanent fix.

Node.js: 8.9.4 x64 npm: 5.6.0

I can reproduce it only in the PRO version

Just have to change @angular/cli version from 1.6.4 to 1.6.5 to fix it

npm install angular/cli@1.6.5 --save-dev

@parthmakadiya12 You need to update your cli globally what you have done changed your package in your project --save-dev update’s your project package. Now the problem is that globally you are running old package and in your project you are running updated packages.

Just run npm update -g and things would get fine. Thanks

cannot reproduce @angular-devkit is required by @angular/cli as dependency maybe something went wrong with npm install

what’s your version of node and npm?
remove node_modules directory and package-lock.json file, retry npm install
sometimes npm’s cache gets confused, reset it with npm cache clean

please let us know if this helps

I just did the following:

Replaced “@angular/cli”: “1.5.4” to “@angular/cli”: “^1.5.4” in “devDependencies” and then run the command: npm update and it gets fixed for me.
