由于这篇文章中概述了一个错误，我最近更新了discord.py ，更新之后，我无法再导入它。
运行import discord会出现以下错误：
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python3.6/site-packages/discord/__init__.py", line 23, in <module>
from .client import Client

from yarl import URL
File "/usr/local/lib/python3.6/site-packages/yarl/__init__.py", line 1, in <module>
from ._url import URL, cache_clear, cache_configure, cache_info
File "/usr/local/lib/python3.6/site-packages/yarl/_url.py", line 56, in <module>
@rewrite_module
File "/usr/local/lib/python3.6/site-packages/yarl/_url.py", line 132, in URL
_QUERY_PART_QUOTER = _Quoter(safe="?/:@", qs=True, requote=False)
File "yarl/_quoting.pyx", line 192, in yarl._quoting._Quoter.__init__
TypeError: __init__() got an unexpected keyword argument 'requote'
列表上的最后一件事是yarl，所以我尝试了import yarl并收到此错误：
Traceback (most recent call last):
File "/usr/local/lib/python3.6/site-packages/yarl/__init__.py", line 1, in <module>
from ._url import URL, cache_clear, cache_configure, cache_info

python的版本是3.6.8。我还在3.6.9的另一台计算机上尝试过此操作，并得到了相同的错误。我已经在装有3.7.7的计算机上尝试了此方法，并且一切正常加载，但是我无法在此计算机上将python升级到3.7，因此希望在3.6上运行。
升级pip对我没有帮助。
yarl如@Orangutan所示强制重新安装并没有帮助我。
但是，以下方法可以解决问题：
mkdir ~/backup
mv ~/.local/lib/python3.6/site-packages/yarl* ~/backup/
pip3 install yarl --force-reinstall --no-cache-dir
