Ubuntu: pip not working with python3.4

Question

Trying to get pip working on my Ubuntu pc. pip seems to be working for python2.7, but not for others.

Here's the problem:

$ pip
Traceback (most recent call last):
File "/usr/local/bin/pip", line 9, in <module>
load_entry_point('pip==1.4.1', 'console_scripts', 'pip')()
File "/usr/local/lib/python3.4/dist-packages/setuptools-1.1.5-py3.4.egg /pkg_resources.py", line 357, in load_entry_point
def get_entry_info(dist, group, name):
File "/usr/local/lib/python3.4/dist-packages/setuptools-1.1.5-py3.4.egg/pkg_resources.py", line 2394, in load_entry_point
break
File "/usr/local/lib/python3.4/dist-packages/setuptools-1.1.5-py3.4.egg/pkg_resources.py", line 2108, in load
name = some.module:some.attr [extra1,extra2]
ImportError: No module named 'pip'

$ which pip
/usr/local/bin/pip

$ python2.7 -m pip //here can be just python, btw
Usage:   
/usr/bin/python2.7 -m pip <command> [options]
//and so on...

$ python3.4 -m pip
/usr/bin/python3.4: No module named pip

From the home/user/.pip/pip.log :

Exception:
Traceback (most recent call last):
File "/usr/lib/python2.7/dist-packages/pip/basecommand.py", line 122, in main
status = self.run(options, args)

shutil.move(old, new)
File "/usr/lib/python2.7/shutil.py", line 303, in move
os.unlink(src)
OSError: [Errno 13] Permission denied: '/usr/bin/pip'

There's no /usr/bin/pip btw.

How can I fix this issue to work with pip and python 3.4 normally? I am trying to use pycharm, but it's package manager also stucks in this problem.

Thanks for attention!

Solution 1

You have pip installed for python 2, but not python 3.

Ubuntu distributes python-pip, python3-pip, python-setuptools and python3-setuptools packages, which you can install (apt-get install etc) as necessary. Thereafter, note that pip installs for python 2, and pip3 installs for python 3 (similar to python, and python3).

Setuptools could be said to provide python's "build" process for packages, and Pip provides its "install" process. Usually you want both present.

If you want the very latest pip / setuptools, you could always get it from PyPA's bootstrap site:

$ curl https://bootstrap.pypa.io/get-pip.py | python3.4

Afterwards you can install the latest setuptools for the appropriate python, e.g

$ python{2.7,3.4} -m pip install -U setuptools

If you try to install these for the system python, you might need root / sudo.

Solution 2

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
sudo python3 get-pip.py

confirm its installation:

pip3 --version    

or

python3 -m pip --version

now go ahead and install your desired packages (for example numpy) using:

pip3 install numpy

or

python3 -m pip install numpy

Here is the reference: https://pip.pypa.io/en/stable/installing/

Solution 3

This worked on my Ubuntu 19.04:

sudo apt install python3-pip

Then pip3 or python3 -m pip to install python packages.

Solution 4

I had a similar issue when running this command on my raspberry pi

python3.4 -m pip install RPi.GPIO

and got this error

/usr/bin/python3.4: No module named pip

resolved it by installing python3-pip

sudo apt-get install python3-pip
