ubuntu - Install pip for python 3.5

Question

SOLUTION My user did not own permissions to the pip directory, I reinstalled Python 3.5 using the sudo -H flag

I'm trying to install Tensorflow for python 3.5 using pip3 -- for reasons described in this github issue -- but when I install using sudo pip3 install *.whl it installs to python 3.4.

How can I redirect pip3 to install into my python 3.5 directory?

I'm running on Ubuntu 14.04

kendall@kendall-Macmini:~/Downloads$ python3.4 -m pip --version
pip 8.1.2 from /usr/local/lib/python3.4/dist-packages/pip-8.1.2-py3.4.egg (python 3.4)
kendall@kendall-Macmini:~/Downloads$ python3.5 -m pip --version
/usr/local/bin/python3.5: No module named pip

It looks like I don't even have pip installed for python 3.5. How can I do this?

I've tried

kendall@kendall-Macmini:~/Downloads$ pip install -U pip
Requirement already up-to-date: pip in /usr/local/lib/python3.4/dist-packages/pip-8.1.2-py3.4.egg

Also,

kendall@kendall-Macmini:~/Downloads$ whereis pip
pip: /usr/bin/pip /usr/bin/X11/pip /usr/local/bin/pip3.4 /usr/local/bin/pip /usr/local/bin/pip2.7 /usr/share/man/man1/pip.1.gz

I can't find any support for upgrading to pip3.5

It seems like I'm missing all sorts of dependencies -- I'm going to try reinstalling

Check: /usr/local/lib/python3.5/dist-packages

You'll either have Pip there or easy_install(part of Pythons setup tools), which can be used to install Pip:

sudo apt-get install python3-setuptools
sudo python3.5 easy_install.py pip

Or you can try:

python3.5 -m ensurepip

Another option is attempting to install from a repository, the package name depends on your distribution:

sudo apt-get install python3-pip pip3

Edit: Try this correction for easy install:

sudo apt-get install python3-setuptools
sudo python3.5 /usr/local/lib/python3.5/dist-packages/easy_install.py pip

I'm assuming that's the directory it's installed to.

Also, you're missing this library for the python3.5 -m ensurepip command:

sudo apt-get install libssl-dev
