When downgrading setuptools 36.2.0 to 36.1.1 I get the above error. Here’s a log output:

This checks out. A minimum reproducible test case had a requirements.txt file of just setuptools==36.5.0 and pylint==1.7.2. Looks like pylint is compiling wrapt in the installation, which is sufficient to trigger this bug.

Added a new line to my .travis.yml file to pip install setuptools==36.5.0 before pip install -r requirements.txt solved the problem for me, just in case anyone else hits the same issue.

Is this issue supposed to be fixed? Still experiencing the error when building on Travis CI. Or is there something wrong on their side?
