pip install unroll: python setup.py egg_info failed with error code 1

About the error code

According to the Python documentation:

This module makes available standard errno system symbols. The value of each symbol is the corresponding integer value. The names and descriptions are borrowed from linux/include/errno.h, which should be pretty all-inclusive.

Error code 1 is defined in errno.h and means Operation not permitted.

About your error

Your setuptools do not appear to be installed. Just follow the Installation Instructions from the PyPI website.

If its already installed, try

pip install --upgrade setuptools

If its already up to date, check that the module ez_setup is not missing. If it is, then

pip install ez_setup

Then try again

pip install unroll

If its still not working, maybe pip didnt install/upgrade setup_tools properly so you might want to try

easy_install -U setuptools

And again

pip install unroll

Heres a little guide explaining a little bit how I usually install new packages on Python + Windows. It seems youre using Windows paths, so this answer will stick to that particular SO:

  • I never use a system-wide Python installation. I only use virtualenvs, and usually I try to have the latest version of 2.x & 3.x.
  • My first attempt is always doing pip install package_i_want in some of my Visual Studio command prompts. What Visual Studio command prompt? Well, ideally the Visual Studio which matches the one which was used to build Python. For instance, lets say your Python installation says Python 2.7.11 (v2.7.11:6d1b6a68f775, Dec 5 2015, 20:40:30) [MSC v.1500 64 bit (AMD64)] on win32. The version of Visual Studio used to compile Python can be found here, so v1500 means Id be using vs2008 x64 command prompt
  • If the previous step failed for some reason I just try using easy_install package_i_want
  • If the previous step failed for some reason I go to gohlke website and I check whether my package is available over there. If its so, Im lucky, I just download it into my virtualenv and then I just go to that location using a command prompt and I do pip install package_i_want.whl
  • If the previous step didnt succeed Ill just try to build the wheel myself and once its generated Ill try to install it with pip install package_i_want.whl

Now, if we focus in your specific problem, where youre having a hard time installing the unroll package. It seems the fastest way to install it is doing something like this:

  • git clone https://github.com/Zulko/unroll
  • cd unroll && python setup.py bdist_wheel
  • Copy the generated unroll-0.1.0-py2-none-any.whl file from the created dist folder into your virtualenv.
  • pip install unroll-0.1.0-py2-none-any.whl

That way it will install without any problems. To check it really works, just login into the Python installation and try import unroll, it shouldnt complain.

One last note: This method works almost 99% of the time, and sometimes youll find some pip packages which are specific to Unix or Mac OS X, in that case, when that happens Im afraid the best way to get a Windows version is either posting some issues to the main developers or having some fun by yourself porting to Windows (typically a few hours if youre not lucky) 🙂
