I'm new to Python and have been trying to install some packages with pip.

But pip install unroll gives me

Command "python setup.py egg_info" failed with error code 1 in C:\Users\MARKAN~1\AppData\Local\Temp\pip-build-wa7uco0k\unroll\

How can I solve this?

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 it's already installed, try

pip install --upgrade setuptools

If it's 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 it's still not working, maybe pip didn't install/upgrade setup_tools properly so you might want to try

easy_install -U setuptools

And again

pip install unroll
