I wanted to install powerline for vim so did 'pip install powerline' to install the module. But the terminal gave me an error.

Tried searching for the issue but got no good result.

The terminal output is as follows:

```
Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "/tmp/pip-install-06bn015i/powerline/setup.py", line 27
        zip_safe = False,
        ^
    SyntaxError: keyword argument repeated

```
