pip command exits immediately on Cygwin

[evan]

This used to work for us, but sometime in the last two months fresh installs of pip in cygwin are broken:

First of all, I believe pip 1.4.1 was still working. Unfortunately, it seems impossible to install a specific version of pip using the get-pip.py script; it seems to always install the latest version so I don't have an easy way to revert to 1.4.1 and confirm.

The OP mentions fresh install, but I am getting the same problem upgrading to 1.5.1. For what it's worth, I now have setuptools 2.1 and pip 1.5.1.

Below are the output of a few commands I have tried:

In Bash: https://dpaste.org/KHTB/raw

I expected to see a list of my installed packages, but I didn't see any.

Now, In the interactive interpreter:

$ python
Python 2.7.5 (default, Oct  2 2013, 22:34:09)
[GCC 4.8.1] on cygwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> print sys.executable
/usr/bin/python
>>> print sys.path
['', '/usr/lib/python2.7/site-packages/setuptools-2.1-py2.7.egg', '/usr/lib/python27.zip', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-cygwin', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr/lib/python2.7/site-packages']
>>> import pip
# At this point the interpreter quits with an exit code of 0
$

Again, in Bash:

$ python -c "import setuptools; print(setuptools.__file__)"
/usr/lib/python2.7/site-packages/setuptools-2.1-py2.7.egg/setuptools/__init__.pyc
$

[qwcode]

you could try the imports individually in /usr/lib/python2.7/site-packages/pip/__init__.py and see if you can find the culprit.

[ariloudev]

Same problem: cygwin64, windows 8.1

@qwcode tried:

from pip.exceptions import InstallationError

And the interpreter exits here. Also tried running python -v to see if it chokes on loading some dependency, but can't see any problems there.

I am not a Python developer, so would appreciate any help on how to get this to work.

[ksze]

Looks like the issue is gone now, using:

• Cygwin 64-bit 1.7.28
• Python 2.7.5
• setuptools 2.1.2
• pip 1.5.2

[bituser]

I am still experiencing this problem. I am running the latest version of everything.

If you required any further details please ask, but I am running the same versions as ksze listed.

[tg123]

This may cause by cygwin python2.7.5-3
I used gdb on python and run pip, then I got a segment fault at (? lackof debuginfo)

So, I built python src on 2.7.6 on my machine (windows 8.1 cygwin 2.83 64bit)
everything runs well

[bituser]

Could I have a little extra detail on how to build python 2.7.6 for cygwin? Did you install a cygwin specific package or just install it as per normal in windows and update Cygwin path?

Thanks.

[SysGrove]

Save problem with cygwin64 and windows 7 (pip3 is making a core dump), bit cygwin32 bit works fine.

[meeotch]

Same here. pip exits with no output on cygwin64, but works under cygwin32.
cygwin 1.7.28-2
python 2.7.5-3
python-setuptools 0.6.34-1

[danielrpa]

Same problem here

cygwin 1.7.28-2
python 2.7.5-3

[Hammerstad]

Same problem with:

cygwin 1.7.28-2
python 2.7.5
python-setuptools 2.2
pip 1.5.4

Had to download a previous version of pip to make it work for now.

[pisacane]

now working for me with binutils recommended here: https://github.com/kennethreitz/requests/issues/1547

[Irfy]

Install the cygwin package libuuid-devel, that will fix it.

[hartmut27]

same problem here.
cygwin64 - cygwin1.dll 1.7.29
python 2.7.5-3
windows 7 64 bit
installing libuuid-devel into cygwin did not solve the bug unfortunatelly.

-------> But switching from cygwin-64bit to cygwin-32bit solved it! (but forking problems may occur in cygwin-32bit: "error: cannot fork() : Resource temporarily unavailable")

[hellerbarde]

For future Unixers in Windows territory:
I'm using cygwin64 on windows 8, 64 bit and I had to install both "binutils" and "libuuid-devel" to make pip work.

[Benoit-DunandLaisin]

I confirm @hellerbarde's tips

[hartmut27]

yes, when installing anything related to "binutils" and "libuuid-devel" in CygWin 64, it works! Great!

[indiv0]

Can also confirm that installing binutils and libuuid-devel in Cygwin64 fixed the problem.

[RockHong]

@indiv0 Confirm it one more :-)

[Ivoz]

Has someone reported these dependencies to cygwin python maintainer?

[akaak]

Confirming that installing both binutils and libuuid-devel (as mentioned by @indiv0) worked for me as well. Cygwin64 version 1.7.30.

[partlyhuman]

Additional confirmation that installing libuuid-devel on cygwin64 1.7.30/win8.1 solved this issue for me.

[procesd]

Still happening in Cygwin64 1.7.31(0.272/5/3), Python 2.7.8, setuptools 5.4.2, pip 1.5.6 and still solved by installing "binutils" and "libuuid-devel"

[hellerbarde]

How can I find the package maintainer of the pip package? I seem to be
unable to find that info.

@hellerbarde you can speak to us here just fine :)

[hellerbarde]

@Ivoz , sorry, i somehow didn't realize that package maintainers are around here as well.

Edit: oh, wait. Are you also a Cygwin package maintainer? Because that would be what I was looking for. I totally forgot that this thread is not in the Cygwin project, so I neglected to mention it.

[Ivoz]

Are you also a Cygwin package maintainer?

Nope, that's why I asked if someone had reported it to them.

[Ivoz]

Issue seemed to be missing dependencies for python in cygwin. If there's anything else please comment
