先尝试下了个CMaker 3.27.5 在windows机器安装了 (看见上面的日志里提的是这个版本)Download | CMake
但 好像是有些变量要设置,但是现在不清楚改怎么设置。

conda install -c conda-forge c-compiler
conda install -c "conda-forge/label/cf202003" c-compiler
试一下这两句,重新安装一下编译器再试试看是不是能正常安装。

我的windows机器没法直接运行这2条命令

conda : The term 'conda' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling

如果手动安装conda 是不是比较麻烦?

哦,我可能搞混了,之前有个人是装了anaconda的环境

等回复,我也一样的问题

可能不少windows机器的同学会遇到这个问题,这个问题如果解决不了会影响后面的上课吗?
我没有anaconda的环境 看错误应该不涉及这个

根据下面的连接 现在准备 新装个VisualStudio 2022 + C++ building tool再重新安装试试

 Building windows wheels for Python 3.10 requires Microsoft Visual Studio 2022.

我已经安装这个解决了,可以的,记得选组件是要选C++桌面开发的

嗯 那就好 我还在下载 :smile:


结贴!按上面的方式 重启机器后 安装上可以 运行
