pip install - Connection reset by peer

Question

When I try to install lxml using pip I had the exception "Connection reset by peer":

Downloading/unpacking lxml

This only happened when installing lxml, other modules got installed with pip no problems. Anybody had the same problem?

You should try with you OS package manager like apt-get install python-lxml — Denis, Dec 14 '12 at 11:51

Try to choose another PyPI mirror, either directly:

pip install -i http://e.pypi.python.org/simple lxml

Or by letting pip find the best mirror:

pip install --use-mirrors lxml

yeah, now even just try to download it from pypi.python.org/simple, I hit network error. I guess something wrong with the mirror itself. – Shengjie Dec 14 '12 at 13:01

@Shengjie If *all* [PyPI mirrors](http://pypi.python.org/mirrors) fail it's more likely a problem on your end of the network. – Dec 14 '12 at 13:07
I am getting lots of "Could not find a version that satisfies the requirement XX" – R Claven Apr 20 '17 at 18:56
Unfortunately it looks like `--use-mirrors` has been deprecated. It isn't available for me at all. See: https://stackoverflow.com/questions/28403263/canonical-replacement-for-use-mirrors – Stephen May 11 '23 at 22:10

In my case, was an ipv6 issue. Some mirrors still don't have full ipv6 access.

Disable ipv6 and try again.

It turns out the mirror I was using somehow is not accessible from the network. The way I got around with it is installing it via OS directly using:

$ apt-get install python-lxml

then copy it to my virtual env:

$ cp -r /usr/lib/python2.7/dist-packages/lxml* /home/dummyuser/work/virt-dev-env/local/lib/python2.7/site-packages/

I then have it in my virtual env:

$ pip freeze
........
lxml==2.3.2
........
