Extras do not work when --editable and a remote URL (eg, git) are used

[lrq3000]

Description

pip chokes when trying to install from a remote url with extras if --editable is specified.

Example:

pip install --upgrade --editable "dummypiplinereturnbug[test] @ git+https://github.com/lrq3000/dummypiplinereturnbug" --verbose

Produces the following error:

ERROR: dummypiplinereturnbug[test] @ git+https://github.com/lrq3000/dummypiplinereturnbug is not a valid editable requirement. It should either be a path to a local project or a VCS URL (beginning with bzr+http, bzr+https, bzr+ssh, bzr+sftp, bzr+ftp, bzr+lp, bzr+file, git+http, git+https, git+ssh, git+git, git+file, hg+file, hg+http, hg+https, hg+ssh, hg+static-http, svn+ssh, svn+http, svn+https, svn+svn, svn+file).

The egg fragment form works fine, but it has been deprecated and planned for removal in pip v25 in #11617:

pip install --upgrade --editable git+https://github.com/lrq3000/dummypiplinereturnbug.git#egg=dummypiplinereturnbug[test] --verbose

How to Reproduce

Use pip install with 3 arguments:

2. an extra
3. from a remote URL

Example:

Output

ERROR: dummypiplinereturnbug[test] @ git+https://github.com/lrq3000/dummypiplinereturnbug is not a valid editable requirement. It should either be a path to a local project or a VCS URL (beginning with bzr+http, bzr+https, bzr+ssh, bzr+sftp, bzr+ftp, bzr+lp, bzr+file, git+http, git+https, git+ssh, git+git, git+file, hg+file, hg+http, hg+https, hg+ssh, hg+static-http, svn+ssh, svn+http, svn+https, svn+svn, svn+file).

@lrq3000 editables from PEP 508 URLs are not supported at the moment, and as far as I know no-one is working on it at the moment. So, as you noted, you need to use egg fragments for now.

So let me close this as the deprecation of egg fragments is tracked in #1289.

@sbidoul Yes they are since #9471 , it's just the extras that are not supported. Seems like a bug, no?

@sbidoul Ah no sorry I spoke too fast, indeed they are not supported at all. Thank you for pointing this out and linking to relevant discussions.
