First, install pip:

sudo apt install python-pip

Usually the old version was installed.

Then,  'pip install Image'

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-aw5SyO/django/

You are using pip version 8.1.1, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

Solution:

sudo python -m pip install --upgrade --force pip 
sudo pip install setuptools==33.1.1

If not completely successful, use 'sudo apt autoremove' as written in the installing history.

Finally:

sudo pip install XXXmodule

dont miss 'sudo'

後面加了 sudo pip install requests

卻提示失敗,無法collect……(好坑)

The directory ‘/home/bzy/.cache/pip/http’ or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo’s -H flag.

最後仔細看了下
sudo pip install requests
的報錯資訊
才知道要加上 -H

sudo -H pip install requests
