我試着安裝nsetools而不是超級用戶。但它拋出下面的錯誤： -

在嘗試使用nsetools我收到以下錯誤： -

    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 

即使我已經安裝了six： -

sudo -H pip install six

有人能告訴我發生了什麼問題嗎？

我強烈建議您不要使用sudo安裝pip軟件包，而是閱讀關於使用Python的虛擬環境，例如virtualenv或pyenv。沒有虛擬環境，你會經常面對錯誤，比如你提到的錯誤。

這應該可以幫助您設置虛擬環境：

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

讀this article，以獲取有關虛擬環境，其目的和用途的想法。
