How to use pip with Python 3.x alongside Python 2.x

python python-3.x python-2.7 pip

Solution 1

The approach you should take is to install pip for Python 3.2.

You do this in the following way:

$ curl -O https://bootstrap.pypa.io/get-pip.py
$ sudo python3.2 get-pip.py

Then, you can install things for Python 3.2 with pip-3.2, and install things for Python 2-7 with pip-2.7. The pip command will end up pointing to one of these, but I'm not sure which, so you will have to check.

Solution 2

What you can also do is to use apt-get:

apt-get install python3-pip

In my experience this works pretty fluent too, plus you get all the benefits from apt-get.

Solution 3

First, install Python 3 pip using:

sudo apt-get install python3-pip

Then, to use Python 3 pip use:

pip3 install <module-name>

For Python 2 pip use:

pip install <module-name>

Solution 4

The shortest way:

python3 -m pip install package
python -m pip install package

Solution 5

If you don't want to have to specify the version every time you use pip:

Install pip:

$ curl https://raw.github.com/pypa/pip/master/contrib/get-pip.py | python3

and export the path:

$ export PATH=/Library/Frameworks/Python.framework/Versions/<version number>/bin:$PATH

I installed Python 3.x (besides Python 2.x on Ubuntu) and slowly started to pair modules I use in Python 2.x.

So I wonder, what approach should I take to make my life easy by using pip for both Python 2.x and Python 3.x?

  Personally, I'd avoid global package installs and use virtualenv. Then you use pip from inside your virtual environment for each project, and you're always using the right one.

This was easy, thanks. sudo python3.2 get-pip.py installs pip and pip-3.2 scripts in /usr/local/bin and both logically use Python 3. sudo python get-pip.py installs pip and pip-2.7 here, so in this case pip uses Python 2.7. I additional created link to pip-3.2 as pip3 and tested: Perfect! :)

Could you elaborate? I don't see how installing distribute has anything to do with not having to specify version of pip you want to use.

On Fedora, it's pip3.3, that is, without the dash between pip and the version. Check /usr/bin to see which pip versions you have there.

On 12.04 I can't do this.

I successfully used this (ie sudo apt-get install python3-pip) and then could install python3 packages using "sudo python3 -m pip install package".

[x]Ubuntu is also using [ pip2 | pip2.7 | pip3 | pip3.4 ]. Is this a change in pip or different between different systems?

As of today, I believe apt-get gets you the outdated 1.5.6 version; if you don't want an AssertionErrror during pip freeze > requirements (or other potential bugs), do install from source for the latest version and save yourself some headache.

After executing I got You're using an outdated location for the get-pip.py script, please use the one available from https://bootstrap.pypa.io/get-pip.py

There's no Python 2 pip, that depends on the OS you're using. For example on Arch Linux pip --version states that's running on python 3.6 by default.

FYI, Mac UNIX also uses [ pip2 | pip2.7 | pip3 | pip3.4 ]

Manjaro / Arch Linux also uses pip#.# (i.e. without the hyphen).

that seems the most intuitive and easy solution to me, thanks!

must be root to install python3-pip

@axd in that case first install pip using sudo apt-get install python3-pip. Assuming you are using python3.

This is likely rephrasing previous comments, but if "pip" doesn't work try "pip3". For me the former points to pip2.7, which (I assume) caused the OP issue.

Despite of installing pip using python3.7 pip is still being used default with Python 2.7 on ubuntu 14.04 :( I have managed to update pip to the latest version ie. 19.3.1 but its still taking default to python2.7. How to make it use with python 3.7?
