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

It seems that your project is written in Python  lt  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
