Ionic - 即使安装了 npm，npm 也不会被识别为内部命令

Question

I am running into a bit of trouble installing a couple ionic cordova native plugins.

Basically if I type npm in my cmd I get the npm cli, if I type ionic I get the ionic cli, if I type cordova I get the cordova cli but:

If I type ionic cordova plugin add cordova-plugin-camera

I get Error: cmd: Command failed with exit code 1 Error output: 'C:\\WINDOWS\\system32\\npm' is not recognized as an internal or external command, operable program or batch file.

C:\\WINDOWS\\system32\\npm is not in my enviroment var path nor is nodejs or npm installed there, so why would the ionic cli look for it there?

Answer 1

With Ionic the version of npm is very sensitive. Not all npm versions work, especially the latest (which ever) always give me troubles.

1. npm i -g npm@5.0.4 (or try a few others if this one breaks)

2. Deleting/renaming your package-lock.json makes the occasional difference.

3. Delete node_modules and retype npm install

Those 3 work for me.

Answer 2
