Can not install Command Line Tools

[fenyi2016]

Hi there,
When I use $ sudo pip install https://github.com/3drobotics/solo-cli/archive/master.zip --no-cache-dir
to install cli, this error came out:

Traceback (most recent call last):
File "/usr/local/bin/pip", line 5, in
from pkg_resources import load_entry_point
File "/usr/local/lib/python2.7/dist-packages/pkg_resources/init.py", line 72, in
import packaging.requirements
File "/usr/local/lib/python2.7/dist-packages/packaging/requirements.py", line 59, in
MARKER_EXPR = originalTextFor(MARKER_EXPR())("marker")
TypeError: call() takes exactly 2 arguments (1 given)

How can I solve this? I'm using Ubuntu14.04 and Python2.7.6.
Thanks!

Hi,

You can run this first sudo pip install --upgrade setuptools
Then, run sudo -H pip install git+https://github.com/3drobotics/solo-cli

After these two steps, you can type solo, it works for me.
