Importing modules from google.cloud package hangs indefinitely

See original GitHub issue

If I install google-cloud in a brand new virtual environment and don’t use the wheel distribution, importing modules from the package causes the program to hang indefinitely.

pip install google-cloud --no-binary :all:  # force pip to install sdist
python -c "from google.cloud import datastore"   # hangs

The only material difference I see between installing wheel vs. egg is compiling the grpcio dependency, which has c extensions.

$ pip show google-cloud
Name: google-cloud
Version: 0.25.0
Summary: API Client library for Google Cloud

$ python --version
Python 2.7.12

$ gcc --version
gcc (Ubuntu 4.9.4-2ubuntu1~16.04) 4.9.4

Installing from wheel distribution works fine, but if a package lists google-cloud as a dependency in its own setup.py, pip won’t install wheels since its not supported in setuptools and the program will hang whenever modules from google-cloud are imported.

I’m running on Ubuntu 16.04 LTS.

@AnupJonchhe it’s been a very long time since I encountered this and I don’t remember what the root cause was anymore for me. From my comment three years ago, it seems like there was something special about my host. Try running strace (or your OS equivalent) of the simple import command:
