Error installing confluent-kafka from source

I downloaded the .tar.gz file from here:

When I run the install command, I get this error. What does it mean and how can I overcome it? This is on CentOS 7. My setuptools are latest-greatest. pip is version 3.


error in confluent-kafka setup command: ‘extras_require’ must be a dictionary whose values are strings or lists of strings containing valid project/version requirement specifiers.

Ideally I want to install confluent-kafka package on a server that’s offline, i.e. lacking online access, thus want to install via source code.
