Upgrading six library to 1.10.0 will fix the issue.

@mrpau-richard - you should retarget for 0.17.x if this is a release blocker for 0.17?

Yeah, this is a release blocker for 0.17.x.

@mrpau-richard where does the six>=1.10.0 come from?

As I read the pip sources, it's not from installing pip itself, must be from some other source.. pip doesn't have dependencies.

[benjaoming]

pip install . works for me on a clean virtualenv.

[mrpau-richard]

Hi @benjaoming you can reproduce this issue if you install first the requirements.txt then run the command pip install .

The six>=1.10.0 come from requirements.txt

I also notice that when I create a clean virtualenv, It will automatically install the six version 1.10.0 and it will override to 1.9.0 if you install the requirements.txt

These are the logs.

@mrpau-richard Interesting, thanks for explaining... so six==1.9.0 is actually what's in requirements.txt, but it seems that you get another version installed, maybe it's a read-only copy in your system.

I'll update the requirements...
