[npm] fatal: Unable to find remote helper for 'git+https'

[vercotux]

It seems there is an issue with some NPM packages which specify their dependencies in a format which uses "git+https" as the URL protocol.

This is the error I get during composer update -vvv:

[RuntimeException]

Here is one example of such an NPM package: meganz/jodid25519

The format used is a valid format. Possible URL protocols in npm package.json dependencies: git, git+ssh, git+http, git+https, git+file

The error comes from Git which does not support git+https. However, NPM and Yarn know how to use it, so we should convert this url to https:// only.

Try the install/update with the --prefer-dist option, in this case, Git is not used.

It appears the logic for this already exists. But why is it not working?
