I can't run pip2, which is installed from its Arch Linux package:
$ pip2
Traceback (most recent call last):
File "/usr/bin/pip2", line 5, in <module>
from pkg_resources import load_entry_point
File "/usr/lib/python2.7/site-packages/pkg_resources/__init__.py", line 47, in <module>
from pkg_resources.extern.six.moves import urllib, map, filter
ImportError: No module named moves
I reinstalled python2-pip2 and python2-setuptools with no results. This has been a problem for months.
While I don't understand the issue, it is possible to reset it by removing locally (--user) installed packages:
Move all packages installed as the user:
mv ~/.local/lib/python2.7/site-packages ~/site-packages-bak
or try to pinpoint the problematic files. In my case, for some reason I had a python file and its pyc file lying around the site-packages directory and just moving them solved my issue:
mv ~/.local/lib/python2.7/site-packages/six.py ~/six.py-bak
mv ~/.local/lib/python2.7/site-packages/six.pyc ~/six.pyc-bak

I have been trying to get pip with python3 on WSL ubuntu 16.04 and have had no success. I have been running sudo apt install --reinstall python3-pip, but still have issues getting pip to work properly.
$ pip3

ImportError: No module named 'distutils'
Also I noticed that I seem to have two versions of python3 installed:
$ ls /usr/lib | grep python
python2.7
python3
python3.5
According to Python 3 documentation, distutils apparently is not deprecated, BUT, my install of 2.7 has disutils, but 3.6 does not.
When I read:
https://docs.python.org/3/installing/
It seemed to say that distutils was being deprecated, but it was not worded clearly if they were talking about distutils or something else.
If anyone knows the definitive answer, please let us know.
So after a lot of pain, I finally gave in. I had made things worse and corrupted my entire python3 installation. I had corrupted too many files trying to fix everything. I ended up uninstalling WSL/ubuntu and reinstalling clean. I made of backup a few things first.
Unfortunately, this seems to be the best option if you have really messed this up, like I did. Being more careful now, python3 is working just fine, with pip. Make sure you follow official docs when you install.
I have virtual environment created for python 3.6. And I have install python3-pyqt5.qtwebkit package with apt-get. The package have installed in global python3.5 and its working, but if I try to import it from venv python3.6 there is import error... How can I install this package in my virtual environment? Or if this is not possible how can I use global package installed in 3.5 in my virtualenv 3.6 python.

In order to use system packages inside a virtual environment, you have to use --system-site-packages option when creating virtual env:
virtualenv --python=python3.6 --system-site-packages env
The same switch is available in Python3's venv.
Much better option is (if applicable in your case) to install all packages inside your virtual env, using pip.
If you look at the contents of the package (using dpkg --listfiles python3-pyqt5.qtwebkit) you'll probably see something like this:
/.
/usr
/usr/lib
/usr/lib/python3
/usr/lib/python3/dist-packages
/usr/lib/python3/dist-packages/PyQt5
/usr/lib/python3/dist-packages/PyQt5/QtWebKit.cpython-35m-x86_64-linux-gnu.so
/usr/lib/python3/dist-packages/PyQt5/QtWebKit.pyi
/usr/lib/python3/dist-packages/PyQt5/QtWebKitWidgets.cpython-35m-x86_64-linux-gnu.so
/usr/lib/python3/dist-packages/PyQt5/QtWebKitWidgets.pyi
/usr/share
/usr/share/doc
/usr/share/doc/python3-pyqt5.qtwebkit
/usr/share/doc/python3-pyqt5.qtwebkit/copyright
/usr/share/doc/python3-pyqt5.qtwebkit/changelog.Debian.gz
The package installs binary modules compiled for a specific python version (in this case: cpython-35m), you won't be able to use those from a python3.6 installation/venv directly because of the incompatible binary names.
For that to work you'd need to symlink all the .so files in the PyQt5 directory to your venv and there change cpython-35m-x86_64-linux-gnu to cpython-36m-x86_64-linux-gnu. Same for the sip libraries, as those are requiered by PyQt5. And that will only work if the ABI is compatible between the two versions.
A quick test with the versions mentioned above shows it works at least for simple scripts, but I can't give any guarantee.
I am on OS X 10.11.2, Anaconda Python 2.7.10.
I was installing some dependencies, and suddenly, my conda command started not working at all. Many people suggest conda install python=2.7.10 but when I try that (or any command, even just conda) I get:
Traceback (most recent call last): File
"/Users/Can/anaconda/bin/conda", line 5, in

How can I repair conda, without using conda itself (as I can't)?
UPDATE: I've completely uninstalled and reinstalled Anaconda. It still gives the same error. I've tried pip and it also fails with the same error. I verify it's Anaconda's pip as which pip returns /Users/Can/anaconda2/bin/pip. Why is Anaconda broken?
I had the same issue, it is successfully fixed by just replacing the _io.so file.
sudo find / -name _io.so
copy the path of the _io.so file which DOES NOT belong to python-2.7.11. For example, copy the path of _io.so which is under python-2.7.5:
/usr/local/Cellar/python/2.7.5/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload/_io.so
Replace the '/Users/Can/anaconda/lib/python2.7/lib-dynload/_io.so' file with the _io.so that you just found.
cp /usr/local/Cellar/python/2.7.5/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload/_io.so /Users/Can/anaconda/lib/python2.7/lib-dynload/
Then it will work.
I'm trying to use the virtualenvwrapper to make a python 3 based virtualenv. However,I'm when I pass the optional interpreter argument, I'm seeing this error. I'm running Ubuntu 15.04. I tried reinstalling virtualenv and virtualenvwrapper without success. Thanks for all your help!

I come across same issue, but after I downgrade virtualenv to 12.0.2, this problem disappears.
This is sort of a workaround for now.
Create a virtualenv using pyvenv.
# install pyvenv on Ubuntu
sudo apt-get install python3-venv
To minimize disruption in your normal workflow, pass a destination directory that is the same as the one used by virtualenvwrapper Like so,
pyvenv example ~/.virtualenvs/example
This is automatically working with workon and cdproject commands. I don't use much else that is provided by virtualenvwrapper
Hope this helps.
You can upgrade to the most recent version of virtualenv, with:
sudo pip install --upgrade https://github.com/pypa/virtualenv/archive/master.zip
virtualenv --version
# Returns 15.2.0.dev0 when I ran it
The following command then works:
mkvirtualenv scriptcutter --python=/usr/bin/python3
Apparently, the develop branch was dropped, so the URL with "develop" will no longer work. My answer was based off of #pjotr_dolphin's comment, with the URL updated.
I created a virtualbox with a fresh install of ubuntu 9.10.
I am trying to get MySQLdb to run on python but I'm failing at the import MySQLdb
I first tried sudo easy_install MySQL_python-1.2.3c1-py2.6-linux-i686.egg and then sudo apt-get install python-mysqldb.
Both apparently installed ok, but gave me the following error message when in python I have the import line:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python2.6/dist-packages/MySQL_python-1.2.3c1-py2.6-linux-i686.egg/MySQLdb/__init__.py", line 19, in <module>

ImportError: libmysqlclient_r.so.15: cannot open shared object file: No such file or directory
I have already installed MySQL and it is running, if that matters at all.
I tried following this, but failed in step 2
Your MySQLdb egg installation looks like it is not working properly. You should go into /usr/local/lib/python2.6/dist-packages and remove it.
The Ubuntu python-mysqldb package should work fine. Unless you have a good reason, you should stick to your distribution's package manager when installing new software.
