Error while installing robotframework -ride

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

I have gone through this sequence-------------

Download Python 2.7.15 from

PATH = C:C:\Python27;C:\Python27\Scripts 
(Is this we have to set in User Variable or System Variable?)

Then download wxPython from this link (Download this version wxPython2.8-win64-unicode-


Download setuptools ( for Python from


Download PIP files (pip-10.0.1.tar.gz) from

Now Extract the Setuptools

After extracting from the same folder TYPE "cmd" it will open then run this commend

"python install"

Now Extract the PIP files

After extracting from the same folder TYPE "cmd" it will open then run this commend

"pip install robotframework"

On the cmd run these commends one-by-one

pip install robotframework-ride
pip install robotframework-selenium2library
pip install selenium
pip install decorator
pip install docutils
pip install xlrd
pip install xlwt
pip install xlutils
pip install pigments

But pip install robotframework-ride unroll gives me

D:\Python\pip-10.0.1\pip-10.0.1>pip install robotframework-ride
Collecting robotframework-ride

Complete output from command python egg_info:

    execfile(join(ROOT_DIR, 'src', 'robotide', ''))
