This can be worked around by using python 3.6.5 either by using brew switch 3.6.5 or by using this pyenv workaround.

However installation still fails:

Looking at the repo for inflector I found an issue about python3 compatibility.

There is a workaround for python2 I found (see this comment):

Found a workaround: just tell pip to install version 5 of clang: pip install clang==5.0 then run pip install --upgrade --pre CodeIntel and it should work again.

[hongnguyenhuu96]

I have the same issue as you, but install clang==5.0 does not solve the problem

Your install fails because of esprima, not because of clang. This time the error is probably because async became a protected keyword. See #5.

Get same error with install clang==5.0
