【问题描述】：
我正在尝试在我的 Mac (Mojave 10.14.5) 上运行 Gmail API Python Quickstart
我已经这样安装了 Google 客户端库：
sudo -H pip install --upgrade google-api-python-client google-auth-httplib2 google-auth-oauthlib
这是输出：
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.

但是当我尝试运行快速入门时：
>python quickstart.py
Traceback (most recent call last):
File "quickstart.py", line 4, in <module>
from googleapiclient.discovery import build
ImportError: No module named googleapiclient.discovery
现在如果我注释掉第 4 行，我会得到：
>python quickstart.py
Traceback (most recent call last):
File "quickstart.py", line 5, in <module>
from google_auth_oauthlib.flow import InstalledAppFlow
ImportError: No module named google_auth_oauthlib.flow
如果我注释掉第 5 行，我会得到：
>python quickstart.py
Traceback (most recent call last):
File "quickstart.py", line 6, in <module>
from google.auth.transport.requests import Request
ImportError: No module named google.auth.transport.request
我还尝试重新启动我的终端 - 并重新启动我的机器。
为什么找不到任何 Google 客户端库模块？
【问题讨论】：
-
pip 是否指向 python3？
-
>pip -V pip 19.1.1 from /Library/Python/2.7/site-packages/pip (python 2.7)
