npm install -g generator-angular gives error (requires a peer of)

Question

Learning Node and trying to install generator-angular

running npm install -g generator-angular

WARN EPEERINVALID generator-angular@0.14.0 requires a peer of generator-karma@>=0.9.0 but none was installed.

What does it means and how can I install it?

Answer 1

You should try to install all the components in the same time.

npm install -g grunt-cli bower yo generator-karma generator-angular

worked for me.

Answer 2

就我而言，解决方案是在一行中安装

npm install -g yo generator-karma generator-angular

Answer 3

npm@3 no longer install peerDependencies automatically. This warning is shown as a result of this change.

If you are not running the tests you do not have to install karma .
If you are, npm install karma>=0.9.0 manually.
