Python packaging trouble(Ppt): Getting error when trying to run my packaged project that uses a non-.py file from the command line
Question
After doing $ pip install path/to/MyProject-0.1.0.tar.gz I am able to successfully do import myproject from every directory on my computer using the python interpreter.
However, my goal is to be able to just run $ myproject from every directory. When I run $ myproject I get this:
IOError: [Errno 2] No such file or directory: '/home/username/.virtualenvs/vir_env/local/lib/python2.7/site-packages/myproject/myproject_style.cssc'
I looked in the /home/username/.virtualenvs/vir_env/local/lib/python2.7/site-packages/myproject/ dir and the myproject_style.css file is there.
Notice the error says cssc instead of css . I don't know why I get this error because the program runs perfectly fine when I navigate to the myproject dir and do $ python __init__.py

The problem is not that obvious but I think I know what's wrong.
This line of code:
path_to_myproject = os.path.abspath(__file__)
can return not only ".../__init__.py", but also ".../__init__.pyc" string
Thus this line of code:
path_to_myproject_css = path_to_myproject.replace("/__init__.py", "/myproject_style.css")
will not only take __init__.py, but also __init__. pyc - a byte-compiled version of your py module. That's the most possible reason why you get cssc instead of css ; you just get "/__init__.py" replaced by "/myproject_style.css" in string ".../__init__.pyc".
