我已经在另一台电脑上安装了一次pyqt5。
我正在尝试在我的笔记本上安装pyqt5。
我的笔记本规格是:64位AMD Ryzen 7 5800HMS Windows 10 Pro
我试过了:> pip install pyqt5在cmd错误:

我搜索了这个错误，并尝试了几个解决方案:
> pip install --user --upgrade pip
> pip install pyqt5
> pip3 install pyqt5
> python3 -m pip install PyQt5
> python -m pip install --upgrade pip
> python -m pip install pyqt5
另外，我读到文章说我的python版本是3.10或更高版本可能会导致问题，所以我尝试重新安装python版本到3.9。
以上的解决方案似乎不能解决问题
我能够通过安装最新的Python 3.10.5版本来解决这个问题，单独更新pip并没有帮助。在此之前我使用的是Python 3.8.9。
您可能在计算机上的其他地方安装了不是最新版本的python，并且您的系统环境变量指向该版本。确保在其他程序或库中没有安装Python。例如，我在MSYS2中安装了一个python，一旦我从计算机上卸载它，它就安装了。
对于我来说，安装5.12.2版本的PyQt5解决了这个问题。
pip install PyQt5==5.12.2
Pip install PyQtWebEngine==5.12
