Question

我无法导入aiohttp，但好像已经安装了它。尝试导入时，出现以下错误。

我尝试卸载aiohttp，然后重新安装多次。

我的代码：

import aiohttp

错误：

Traceback (most recent call last):
  File "/Users/shiling1/PycharmProjects/python_code/111.py", line 1, in <module>
    import aiohttp
  File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/aiohttp/__init__.py", line 6, in <module>

    from typing import ( #noqa
ImportError: cannot import name 'Coroutine'

安装aiohttp：

$ pip install aiohttp -t /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/
