Yesterday I was testing some python code in my raspberry pi 3 (raspbian jessie), it required the package pytz, so I did:
sudo python3 -m pip install pytz
And then this happens:

It's not only with pytz, I tried to update/upgrade/reinstall pip with:
sudo python3 -m pip install -U pip
And the same error happens
Any idea about how to solve this problem?
I was searching and trying to solve it yesterday
and everything I can do right now is format the SD card.
My Pip version is 1.5.6 but I can't update it, even downloading the code and running setup.py, same problem.
I tried everything I could, and in my case I will recommend:
Copy all your important codes, changes, documents...
Format the SD and start all over again
I've been having short blackouts lately, that corrupted the SD card.

I am following the 2nd edition of Head First Python by Paul Barry to try and learn to use python. I've made it to a point where I have created a function, put it in a module, then created a distribution file for that modules. Now I want to install it on my computer, but I can't seem to get the distribution file to run on my computer.
My code inserted into Windows 10 command prompt and the resulting errors:

You are using pip version 9.0.3, however version 18.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.
I'm very confused because the file definitely exists in the spot that I am specifying. How do I get it installed?
the file exists in the folder that I expect it to
I am trying to install spacy. I am on CentOS Linux
!pip install -U spacy
in a jupyter notebook and everything was working fine. During the installation, I realized I intended to include the --user command since I intended to install for my user only, so I hit ctrl-c. At this point the installation is incomplete.
Trying to install the package again with pip is now giving me an error, regardless of whether I include the --user flag. I think the error, below, is related to the incomplete build. Does anyone know how to fix this?

When installing tensorflow-gpu 1.4.0 using pip in Windows 10 (Python 3.5), I get the following strange error. Very interestingly, each time I run
pip.exe install tensorflow-gpu
it downloads a small but seemingly random part of the package, then raises the following exception:

I tried turning off my antivirus, in case that was killing it, but it didn't help.
In the end, I managed to install it by downloading the .whl from PyPI manually, then running pip.exe install path/to/.whl, but I'd like to understand what caused the original failure.
Any ideas?
This issue has been documented here, you can update to python 3.6 or install and enable the win_unicode_console package to solve it
https://bugs.python.org/issue32245
Switch to cmd with administrator rights to run the command：
pip3 install --ignore-installed --upgrade tensorflow-gpu -i https://pypi.tuna.

I am trying to deploy python flask application using apache2 and mod-wsgi.
I am following this link.
While installing mog-wsgi using the command sudo apt-get install libapache2-mod-wsgi ,I see these lines at the end
apache2_invoke: Enable module wsgi
Action 'configtest' failed.
The Apache error log may have more information.
apache2_reload: Your configuration is broken. Not restarting Apache 2
Is this a smooth installation?
Also, in step 1 of the link when I tried to create a virtual environment using the command
sudo virtualenv venv
This gives me error sudo: virtualenv: command not found
So, I tried to install virtualenv using sudo pip install virtualenv, I am getting this huge error in red(exception).

This only happened when installing lxml, other modules got installed with pip no problems. Anybody had the same problem?
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
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
........
In my case, was an ipv6 issue. Some mirrors still don't have full ipv6 access.
Disable ipv6 and try again.
