ModuleNotFoundError:没有名为“websockets.datastructures”的模块

我不知道如何在Ubuntu上修复这个错误。我正在尝试使用FastApi运行uvicorn服务器
uvicorn.run("api:app", host="0.0.0.0", port=3100, reload=True, workers=10)
我试过pip3 install websockets：

需要更新setuptools和pip
pip3 install -U setuptools
pip3 install -U pip

我也有同样的问题，我不知道为什么会这样，但我至少给你看看我的解决办法。
最好的办法是跑步：
pip uninstall websocketspip install websockets
但是由于某些原因，这个命令无法为我卸载它，所以我手动完成了它。
因为u在Ubuntu中，所以以root用户的身份打开这个文件夹：
/usr/local/lib/python3.8/dist-packages/websocket
然后你可以在websockets当前版本文件手动下载这些文件。
在我的例子中，我注意到在我的旧websockets文件夹中，我没有websockets.datastructures，也没有其他一些文件，比如文件夹、legacy和extensions，所以我只是将整个库解压缩到上面引用的路径上，这样就可以了。

对我来说，这两个答案中的任何一个都是有效的。我只是用以下方式升级websockets：
