Installed module using pip, not found

I am trying to install a package called "simpleguitk" via pip. (On Ubuntu 16.04 with Python 3.5)
After running

sudo -H pip3 install simpleguitk

it says installation is completed successfully. (Except for the pygame dependecy which is actually optional)

Collecting simpleguitk
Using cached SimpleGUITk-1.1.3.tar.gz
Collecting Pillow>=2.0.0 (from simpleguitk)
Using cached Pillow-3.4.2-cp35-cp35m-manylinux1_x86_64.whl
Collecting pygame>=1.9.0 (from simpleguitk)
Could not find a version that satisfies the requirement pygame>=1.9.0 (from simpleguitk) (from versions: 1.9.2.dev1, 1.9.2b7, 1.9.2b8)
No matching distribution found for pygame>=1.9.0 (from simpleguitk)

I cannot find the package at /usr/local/lib/python3.5/dist-packages or /usr/lib/python3.5 or /usr/lib/python3

When I try to import the module it says:

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named 'simpleguitk'

I tried to reinstall it, but running:

sudo -H pip3 uninstall simpleguitk

returns: "Cannot uninstall requirement simpleguitk, not installed "

I have tried this on both pip 8.1.2 and pip 9.0.1 with the same results. I have even reinstalled Ubuntu, but still the same.

I think Python Path is wrong as it does not have python 3.5 but I do not know how to fix it

['', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-x86_64-linux-gnu', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages/gtk-2.0']

Solution 1:

Make sure you're installing it for the version of python you're using, with

/path/to/your/python -m pip install <package>

Solution 2:

pip needs python, and sometimes the python you are trying to execute your *.py may not be same as the python binary used by pip.

Can you retry installing following these steps:

which python

Let's say it prints:

/usr/bin/python

Means you can use:

/usr/bin/python -m pip install <package>

Or you can try to choose from the different versions you have of python.

Now try executing you *.py using

/usr/bin/python *.py

Solution 3:

The module may be installed but the program doesn't run. This happens because of 2 different versions of python co-existing. So run your Py Script with the location of the python version you have installed the module for, say usr/bin/python python.py or /usr/bin/python3 python.py.

Hope this helps in your progress!
