'develop' command does not support --home option

The 'develop' command doesn't support the '--home' option. This gets used by pip when installing editable packages with '-t', yielding the following error:

$ pip2 install -e . -t www/lib/

Not sure if this should be considered a bug in setuptools or pip; apologies in advance if this is expected behavior and pip should just be doing something different.

I can confirm this with pip 7.1.0. Any way around this?

Looking at the source, it seems the develop command does not accept a --home parameter. The distutils install command does, however, so that may be what pip is expecting when passing it to develop. The develop command is derived from the easy_install command, so has a different interface than that of the install command.

At first blush, then, this appears to be a bug in pip. Maybe pip should be passing --install-dir, or maybe pip would like develop to support the --home parameter. It's not immediately clear to me what that would imply, but I'd entertain a patch to support it if appropriate.

[ryegye24]

Any movement on this lately? It's still happening on version 9.0.1

[jakul]

I'm having the same issue

[RonnyPfannschmidt]

pypa/pip#4390 is the current issue tracking this as its a pip bug

[dwt]

@maintainers: Any progress on this issue? Is there anything that can be done to get this moving forward? It seems implementing --home for develop could be entirely possible?

My understanding is that the discussion about this issue has been moved to #2589, so I will close this issue for the time being (everyone is welcome to continue the conversation there 😄)

The good news is that lately there have been several discussions on editable installs and PEP 660, so we might be able to address this issue 🤞
