FATAL: Amazon Linux support is very experimental at present...
if you would like to work on improving it, please ensure you have backups

The following error when trying to install virtualenv == 15.1.0 with pip

Traceback (most recent call last):
  File "/usr/bin/pip", line 11, in <module>
    load_entry_point('pip==9.0.3', 'console_scripts', 'pip2.7')()

    raise ImportError("Entry point %r not found" % ((group, name),))
ImportError: Entry point ('console_scripts', 'pip2.7') not found

solution

In my case it works with:

# easy_install pip==9.0.3
# easy_install virtualenv==15.1.0

Digression/End of support period for Amazon Linux AMI
