Answer 1

I recommend you try this:

pip install --upgrade pip setuptools

Based on https://github.com/GoogleCloudPlatform/google-cloud-python/issues/2990.

Answer 2

This worked for me on Ubuntu 16.04.

1. Uninstall pip3

   sudo apt-get purge --auto-remove python3-pip
   

2. Go to your home directory

   cd $HOME
   

3. Search for any other pip3 links

   sudo find . -name 'pip3'
   

4. Delete all the links using rm if any were found

5. Download/Clone pip from here (via git for example)

   git clone https://github.com/pypa/pip
   

6. Go to the downloaded directory

   cd pip
   

7. Install pip3 (you might need to add sudo in front of it)

   python3 setup.py install
   

This will install the latest version of pip and remove the error without loss of any packages.
