Install ionic and cordova with npm commands, and the version installed on my system is as follows:

C:\Users\itsvse_pc>node -v
v8.9.2

C:\Users\itsvse_pc>npm -v
5.5.1

Execute the global install command:

The error is as follows:


C:\project\android>npm install -g cordova ionic
npm WARN optional SKIPPING OPTIONAL DEPENDENCY:http-proxy@1.17.0(node_modules\ionic\node_modules\http-proxy):

Solution:


Then try reinstalling it again!



Check if the installation is successful
If you want to see the storage path of the npm global installation package, you can run npm list -g
