pip install fails if executed globally

[diegoperini]

I wanted to experiment with the library and tried to install it without virtualenv, the result was an error like below.

mypc:Desktop $ pip install imagesoup
Collecting imagesoup
  Using cached imagesoup-0.0.10.tar.gz
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "/private/var/folders/fc/n3pcr4jd2vn3byw8znm9xmtc0000gn/T/pip-build-ZXQMxl/imagesoup/setup.py", line 15, in <module>
        with open(os.path.join(here, 'imagesoup', '__version__.py'), 'r', encoding='utf-8') as f:
    TypeError: 'encoding' is an invalid keyword argument for this function

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/fc/n3pcr4jd2vn3byw8znm9xmtc0000gn/T/pip-build-ZXQMxl/imagesoup/

Below is my dev machine info.

I can say that pip install ImageSoup globally works for me.

OS: Windows 10 Enterprise

$ python --version
Python 3.4.4 

$ python

Thanks @diegoperini and @Leustad. Both of you were right. The module was working on Python3 but not on Python2.7. Solved!

Seems to be fixed. Thank you.
