dont use python2.7, change to use python3.X

sudo apt-get install python3-setuptools
sudo python3  setup.py install

[plam4u]

thanks @thaihau
this solved the issue for me.

This is because of benjaminp/six#210
Downgrading six is a temporary workaround

pip install six==1.10

[filipemontt]

same... not solve with python3 and not pip install six==1.10

[r0alt]

dont use python2.7, change to use python3.X

sudo apt-get install python3-setuptools
sudo apt-get install python3-pip <-- dev-packages also needed
sudo python3 setup.py install

[filipemontt]

Works with 2.7

@JackLeo using python 2.7 and six 1.10 solved the problem.

Hi
