Mac更新完系统出现两步报错及解决方法

时间：2024-07-18 15:22:12

Mac更新完系统，通过命令行准备编译C++文件时，报错：

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools)

解决方法：更新xcode，在命令行运行

xcode-select --install

安装完，重新编译，报错：

CMake Error at /opt/homebrew/Cellar/cmake/3.25.0/share/cmake/Modules/CMakeTestCCompiler.cmake:70 (message):
  The C compiler

    "/Library/Developer/CommandLineTools/usr/bin/cc"

  is not able to compile a simple test program.

  It fails with the following output:
