Installing AWSCLI on OSX – Problems uninstalling six

I had to install the aws cli on os-x the other day and ran into a problem towards the end of the install. I used the instructions provided by Amazon AWS here: http://docs.aws.amazon.com/cli/latest/userguide/installing.html

 

I opted to use the pip install method (http://docs.aws.amazon.com/cli/latest/userguide/installing.html#install-with-pip) since that seemed the least fiddly. The instructions provided by amazon are thorough, and likely all that you need:

 

  • Ensure you have python installed and that it’s a supported version, and how to upgrade
  • how to install pip (a python package manager)
  • installing the awscli

 

Unfortunately, when I ran the commmand to install the client:

$ sudo pip install awscli

 

The install ended with the following error:
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:

After a few failed attempts and some searching I found the following suggestion (look for mmtsweng’s comment on Nov 23, 2015):

$ sudo -H pip install awscli --upgrade --ignore-installed six

Using the above command allowed for a clean install of the awscli.
