It seems that your project is written in Python < 3. This is because the file() builtin function is removed in Python 3. Try using Python 2to3 tool or edit the erroneous file yourself.

EDIT: BTW, the project page clearly mentions that

Gunicorn requires Python 2.x >= 2.5. Python 3.x support is planned.

file is not defined in Python3  which you are using apparently  The package you re instaling is not suitable for Python 3  instead  you should install Python 2 7 and try again   See  http   docs python org release 3 0 whatsnew 3 0 html builtins

file   is not supported in Python 3  Use open   instead  see Built-in Functions - open
