Why does pip install fail for the Python Watson Developer Cloud

问题

Here is the error I'm seeing. Is there something wrong in my install? Any help would be appreciated.

Installing collected packages: six, ipaddress, asn1crypto, enum34, pycparser, cffi, cryptography, pyOpenSSL, watson-developer-cloud
  Found existing installation: six 1.4.1
    DEPRECATION: Uninstalling a distutils installed project (six) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.
    Uninstalling six-1.4.1:

回答1:

Its a Mac OSX permission related problem. If you search for OSError: [Errno 1] Operation not permitted: you will find possible resolutions, favourites being:

brew install python

pip install --ignore-installed six

or using virtualenv

There is an entire discussion about this here : Six issue when installing package

The solution that worked for me is :

sudo pip install watson-developer-cloud --upgrade --ignore-installed six
