Adding

install_requires=['pathlib', 'h2', 'async-timeout>=1.3.0', 'multidict'],

does not solve it. I install manually.

Sorry for this confusion, but grpclib supports only Python >= 3.5 (intentionally) and only asyncio (currently), documented this in the README as much as I can. You can use grpcio library from Google if you have to develop with Python 2.7 support.

We are in our company using grpcio from the client-side (legacy project on Python 2.7), and going to use grpclib on the server-side (new services on Python >= 3.5).

@vmagamedov is it comment for #4 ? What it have to do with the missing pathlib? Have you tested on the Python 3.5 clean install?

[vmagamedov]

pathlib module is from the standard library since Python 3.4: https://docs.python.org/3/library/pathlib.html

From the traceback I can see that pathlib is used in the setup.py script of the async-timeout library, and async-timeout is also PY3-only library.

Please try to install grpclib with Python 3.5 or higher, everything should be just fine. More information about installation you can find in the README.

Thank you for cooperation.
