             Summary: "cordova plugin add" removes other plugins installed from Github 
                 Key: CB-14102
                 URL: https://issues.apache.org/jira/browse/CB-14102
             Project: Apache Cordova
          Issue Type: Wish
          Components: cordova-fetch
    Affects Versions: 8.0.0
            Reporter: Ken Naito
             Fix For: 8.0.0


The cordova platform/plugin add commands use cordova-fetch to get the relevant files. It does this by using npm.

However, npm@5.6.x has an issue when installing modules from Github.
npm modules installed from a Github URL will be removed after installing other npm modules.
The issue is on npm’s Github: https://github.com/npm/npm/issues/17379

For example, using node v9.5.0, npm v5.6.0 and cordova 8.0, run

$ cordova plugin add https://github.com/knight9999/HelloWorldPlugin.git

This adds helloworldplugin into the node_modules directory, as shown below:

$ ls node_modules/
fs-extra        helloworldplugin    jsonfile        universalify
graceful-fs        install            npm

If we add further plugins like so:

$ cordova plugin add cordova-plugin-camera

The previous modules in node_modules directory disappear.

$ ls node_modules/
cordova-plugin-camera

This is fixed in npm@5.7.1, as mentioned in the issue link above.

It is possible that the user cannot update their global npm version due to some other dependencies. I suggest that we add a way for the user to override the npm executable which is used by Cordova. For example, we could add an environment variable as below, which would be used instead of the global npm:

CORDOVA_NPM=/home/user/bin/npm
