I tried installing nsetools without being a superuser. But it was throwing the below error:-

On trying to use nsetools I am getting the below error:-

    from .nse import Nse
  File "/Library/Python/2.7/site-packages/nsetools/nse.py", line 26, in <module>
    import six
ImportError: No module named six

Even though I have six installed:-

sudo -H pip install six
Requirement already satisfied: six in /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python

Can someone let me know what is going wrong?

Answer 1

I strongly advise you not to install pip packages with sudo , instead read about using virtual environments with Python, such as virtualenv or pyenv . Without virtual environment you will constantly face errors such as the ones you mentioned.

This should help you with setting up the virtual environment:

$ pip install virtualenv
$ virtualenv your_virtualenv_name
$ source your_virtualenv_name/bin/activate
(your_virtualenv_name) $ pip install nsetools

Read this article to get the idea about virtual environments, their purpose and usage.
