在python3.6上导入yarl或discord.py时出现问题

由于列出的错误，我最近更新了discord.py在这篇文章中 https://stackoverflow.com/questions/63027848/discord-py-glitch-or-random-error-typeerror-new-got-an-unexpected-keywor更新后我无法再导入它。

Running import discord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
  File "/usr/local/lib/python3.6/site-packages/discord/client.py", line 34, in <module>
    import aiohttp

    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'

清单上的最后一件事是 yarl，所以我尝试了import yarl并得到这个错误：

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
  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'

python的版本是3.6.8。我还在另一台 3.6.9 机器上尝试过此操作，并得到了相同的错误。我已经在一台 3.7.7 的机器上尝试过这个，一切都正常加载，但我无法在这台机器上将 python 升级到 3.7，所以想让它在 3.6 上工作。

升级中pip没有帮助我。

强制重新安装yarl如@Orangutan 所示并没有帮助我。

然而，以下方法却成功了：

mkdir ~/backup
mv ~/.local/lib/python3.6/site-packages/yarl* ~/backup/
pip3 install yarl --force-reinstall --no-cache-dir
