Question

我正在尝试在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

我还尝试重新启动终端-并重新启动计算机。

为什么找不到任何Google客户端库模块？

Answer 1

我不确定为什么-但也许不支持Python 2.x吗？

一旦我使用Python 3.x，一切都将正常工作：

安装：

sudo -H pip3 install --upgrade google-api-python-client google-auth-httplib2 google-auth-oauthlib

运行脚本：

python3 quickstart.py

Answer 2

pip install google-auth-oauthlib
