安装 pyqt5 时出错（pip install pyqt5）

Question

我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锐龙7 5800H 微软视窗 10 专业版

我试过了： > pip install pyqt5 在 cmd 并有错误：

我搜索了这个错误并尝试了几种解决方案：

> 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，我看了文章说我的python版本是3.10或更高可能会出现问题，所以我尝试将python版本重新安装到3.9。

上面的解决方案似乎没有解决问题

Answer 1

我能够通过安装最新的 Python 版本 3.10.5 来解决问题，单独更新 pip 并没有帮助。在此之前我使用的是 Python 3.8.9。
