Getting RuntimeError even when I have llvm-3.8 installed

I have llvm installed as is evident by

export LLVM_CONFIG="/usr/bin/llvm-config"

and also the ls output

error: command '/usr/bin/python' failed with exit status 1

Please HELP ME!

So you did the following:

$ sudo -E su
$ export LLVM_CONFIG="/usr/bin/llvm-config-3.8"
$ python setup.py build

and you still got the error above?

Yayyy, thank you @pitrou. In my case I used

export LLVM_CONFIG="/usr/bin/llvm-config-6.0" instead of 3.8 in your case.
