安装大纲

具体看图

这里要注意提前安装 Command Line Tools for Xcode。在安装完成后，如果你的mac安装过Xcode,记得要执行以下命令！

sudo xcode-select -s /Library/Developer/CommandLineTools

原因：xcode的存在会让你的mac在使用某些共享库时链接到xcode的文件目录，而问题就出在有些函数中的内容xcode并不存在！

问题1:Cmake -d失败！

如果提示你openblas找不到，请不要一直尝试卸载你的openblas。进行以下操作：

1、打开findablas.cmake并添加以下语句（注意查看你自己的版本号）。

为什么这么干，因为m1的homebrew会把文件安装在opt/homebrew目录下，并非/usr/local目录。

问题2:make出错

如果你在make编译时出现以下错误，那你大概率给自己的mac装了Xcode。

这个时候不要怕，删了Xcode就行了！！！（开玩笑哈哈哈当然不是不行）

真实做法要执行以下命令！

sudo xcode-select -s /Library/Developer/CommandLineTools

原因：xcode的存在会让你的mac在使用某些共享库时链接到xcode的文件目录，而问题就出在有些函数中的内容xcode并不存在！
