Why can't I import the Google Cloud client lib

I'm working in Python 2.7.10.

i'm just trying to run from google.cloud import storage, but I get ImportError: No module named google.cloud.

google-cloud appears to be installed correctly. pip install google-cloud returns Requirement already satisfied: google-cloud in /Library/Python/2.7/site-packages (0.34.0), and pip show google-cloud returns:

EDIT: thanks to Duy below for reminding me about the next step. Running pip install google-cloud-storage throws a bunch of errors:

I don't understand what the environment error is, and all my searches run down unhelpful rabbit holes.

回答1:

You must use a python environment.

pip install virtualenv
virtualenv <your-env>
source <your-env>/bin/activate
<your-env>/bin/pip install google-cloud-python

Check here for more details about virtualenv https://cloud.google.com/python/setup

回答2:

The google-cloud package is deprecated, you should uninstall it and install google-cloud-storage instead.

回答3:

You forget to install pip install google-cloud-storage
