1 问题报错

报错如下：

  Preparing metadata (pyproject.toml) ... error
  error: subprocess-exited-with-error

  × Preparing metadata (pyproject.toml) did not run successfully.

  note: This error originates from a subprocess, and is likely not a problem with pip.

2 解决办法

解决方案：将python版本回退到3.11

因为我当前的python版本是3.12.7，这个版本是anaconda自带的。为了成功安装PyQt5，就重新下载了windows下的python 3.11安装程序。

• 下载windows 64位的python 3.11安装程序，双击安装，将它安装在D:/software/python/python311下面。
• 配置Path环境变量。安装后将D:/software/python/python311和D:/software/python/python311/Scripts 2个路径添加到Path环境变量中，并且放到anaconda目录的前面，这样以后在命令行输入python，就默认找的是python311目录下的python，而不是anaconda自带的python3.12.7。
• 重新安装PyQt5和PyQt5-tools。
  • pip install PyQt5
  • pip install PyQt5-tools 这两条安装命令都成功执行，那么PyQt5就成功的安装ok。
