1.python的版本是3.10.2

2.背景是：想用python+pyqt5来学习python 的GUI编程的，

3.在安装pyqt5-tools时报错如下：

C:\Users\bj65d5>pip install pyqt5-toolsCollecting pyqt5-toolsUsing cached pyqt5_tools-5.15.4.3.2-py3-none-any.whl (29 kB)Collecting pyqt5==5.15.4Using cached PyQt5-5.15.4.tar.gz (3.3 MB)Installing build dependencies … doneGetting requirements to build wheel … donePreparing metadata (pyproject.toml) … errorerror: subprocess-exited-with-error

During handling of the above exception, another exception occurred:

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

× Encountered error while generating package metadata.

╰─> See above for output.

note: This is an issue with the package mentioned above, not pip.

hint: See above for details.

4.遇到问题后从网上搜索解决办法

大都是说需要先安装wheel

pip install wheel

但是操作后没有能解决问题

4.1.后来看到一个是说可能是版本兼容的问题

因为3.10.2是目前最高的版本，所以尝试安装3.7.6。

5.最后的解决方法

安装python3.7.6后问题解决，在这里做个记录
