`ionic cordova plugin add` fails, `cordova plugin add` works.

[janpio]

Short description of the problem:

This one plugin is strange:

PS C:\Users\Jan\Documents\v8Test> ionic cordova plugin add https://github.com/phonegap/phonegap-mobile-accessibility
> cordova plugin add https://github.com/phonegap/phonegap-mobile-accessibility --save
✖ Running command - failed!

[ERROR] Cordova encountered an error.
        You may get more insight by running the Cordova command above directly.

[ERROR] An error occurred while running cordova plugin add https://github.com/phonegap/phonegap-mobile-accessibility --s
... (exit code 1):

        Error: Failed to fetch plugin https://github.com/phonegap/phonegap-mobile-accessibility via registry.
        Probably this is either a connection problem, or plugin spec is incorrect.
        Check your connection and plugin name/version/URL.

vs.

PS C:\Users\Jan\Documents\v8Test> cordova plugin add https://github.com/phonegap/phonegap-mobile-accessibility
Adding phonegap-plugin-mobile-accessibility to package.json
Saved plugin info for "phonegap-plugin-mobile-accessibility" to config.xml

Note that the plugin has a different repo name (phonegap-mobile-accessibility) than plugin name (phonegap-plugin-mobile-accessibility) but that should be no problem.

What behavior are you expecting?

Both working.

Post the output of ionic info below please

@ionic/cli-utils : 1.3.0
Cordova CLI      : 7.0.1

Interestingly the cordova commands also fails sometimes, but works if you remove the plugin first:

error: cannot spawn sh: No such file or directory

Does Windows have sh?

[janpio]

I don't think so.

But this shouldn't be relevant as both commands (ionic vs. ionic cordova) should do exactly the same thing, right?

[imhoffd]

Should be. It was just something I noticed. I think a plugin hook is doing something naughty. Not sure why it only propagates with ionic cordova.

[janpio]

The plugin I tried to install in my original post is requiring two other plugins to be installed. This seems to be very brittle and only work sometimes on my machine. No idea why, though.

[cocowalla]

Got the same issue. Only seems to be a problem when adding a plugin from Github - ones from npm work fine.
