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) File "/usr/lib/python2.7/dist-packages/pip/commands/install.py", line 283, in run requirement_set.install(install_options, global_options, root=options.root_path) File "/usr/lib/python2.7/dist-packages/pip/req.py", line 1431, in install requirement.uninstall(auto_confirm=True) File "/usr/lib/python2.7/dist-packages/pip/req.py", line 598, in uninstall paths_to_remove.remove(auto_confirm) File "/usr/lib/python2.7/dist-packages/pip/req.py", line 1836, in remove renames(path, new_path) File "/usr/lib/python2.7/dist-packages/pip/util.py", line 295, in renames 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!

Answer 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.

Answer 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
