Installing modules using pip fails

I am trying to install numpy using pip3. This is the command I used:

pip3 install numpy (also tried with sudo but it gives same error)

But I get the following error:

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/pip/_vendor/__init__.py", line 33, in vendored
    __import__(vendored_name, globals(), locals(), level=0)
ImportError: No module named 'pip._vendor.distro'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/local/bin/pip3", line 11, in <module>
    load_entry_point('pip==9.0.1', 'console_scripts', 'pip3')()

subprocess.CalledProcessError: Command 'lsb_release -a' returned non-zero exit status 1

This is the problem when I try to install any Python module This was working fine till just a few days ago.

I tried deleting pip altogether and then reinstalling it. But I get the same error None of the packages get installed via pip now.

I have python 3.6.5

How do I fix this problem?

I had this problem after setting the system default to Python3.5. Oddly, it would appear that pip3 needs Python2.7 to function; running # update-alternatives --config python and selecting Python2.7 got pip3 working again for me. I just installed pygame this way, and it works as expected after switching the system default back to Python3.5. This is on Devuan ASCII and 

$ python --version
Python 3.5.3
$ pip3 --version 
...
subprocess.CalledProcessError: Command 'lsb_release -a' returned non-zero exit status 1

$ sudo update-alternatives --config python
There are 2 choices for the alternative python (providing /usr/bin/python).

  Selection    Path                Priority   Status
------------------------------------------------------------
  0            /usr/bin/python3.5   2         auto mode
  1            /usr/bin/python2.7   1         manual mode
* 2            /usr/bin/python3.5   2         manual mode

Press <enter> to keep the current choice[*], or type selection number: 1

$ python --version
Python 2.7.13
$ pip3 --version 
pip 9.0.1 from /usr/lib/python3/dist-packages (python 3.5)

Edit: On Raspbian Stretch pip3 works with Python3.5 as the system default, so this is clearly not the full story: 

$ python --version
Python 3.5.3
$ pip3 --version
pip 9.0.1 from /usr/lib/python3/dist-packages (python 3.5)
