STEPS TAKEN

Using this reference I performed the following commands:

1. Install pip

   curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
   python get-pip.py
   

2. ADD USER_BASE_PATH to PATH:

   export USER_BASE_PATH=$(python -m site --user-base)
   export PATH=$PATH:$USER_BASE_PATH/bin
   

3. Install awscli

   pip --user install awscli
   

   Had to use the user flag because pip install awscli failed:

   Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/urllib3-1.23.dist-info'
   

   Consider using the --user option or check the permissions.

4. Install aws-sam-cli:

   pip install --user aws-sam-cli

I was having the same issue. Had to upgrade setuptools to fix the issue.You could try running this command:

pip install -U setuptools
