How do I update pip itself from inside my virtual environment?


Question

I'm able to update pip-managed packages, but how do I update pip itself? According to pip --version, I currently have pip 1.1 installed in my virtualenv and I want to update to the latest version.

What's the command for that? Do I need to use distribute or is there a native pip or virtualenv command? I've already tried pip update and pip update pip with no success.

pip is just a PyPI package like any other; you could use it to upgrade itself the same way you would upgrade any package:

pip install --upgrade pip

On Windows the recommended command is:

python -m pip install --upgrade pip

The more safe method is to run pip though a python module:

python -m pip install -U pip

On windows there seem to be a problem with binaries that try to replace themselves, this method works around that limitation.

In my case my pip version was broken so the update by itself would not work.

Fix:

(inside virtualenv):easy_install -U pip

I tried all of these solutions mentioned above under Debian Jessie. They don't work, because it just takes the latest version compile by the debian package manager which is 1.5.6 which equates to version 6.0.x. Some packages that use pip as prerequisites will not work as a results, such as spaCy (which needs the option --no-cache-dir to function correctly).

So the actual best way to solve these problems is to run get-pip.py downloaded using wget, from the website or using curl as follows:

 wget https://bootstrap.pypa.io/get-pip.py -O ./get-pip.py
 python ./get-pip.py
 python3 ./get-pip.py

This will install the current version which at the time of writing this solution is 9.0.1 which is way beyond what Debian provides.

 $ pip --version
 pip 9.0.1 from /home/myhomedir/myvirtualenvdir/lib/python2.7/dist-packages (python 2.7)
 $ pip3 --version
 pip 9.0.1 from /home/myhomedir/myvirtualenvdir/lib/python3.4/site-packages (python 3.4)

Upgrading pip using 'pip install --upgrade pip' does not always work because of the dreaded cert issue: There was a problem confirming the ssl certificate: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version

I like to use the one line command for virtual envs:

curl https://bootstrap.pypa.io/get-pip.py | python -

Or if you want to install it box wide you will need

curl https://bootstrap.pypa.io/get-pip.py | sudo python -

you can give curl a -s flag if you want to silence the output when running in an automation script.

In my case this worked from the terminal command line in Debian Stable

python3 -m pip install --upgrade pip
