MacOS Ventura下CLion提示C编译器识别未知问题求助

问题现象 #

更新MacOS Ventura并同步更新CLion后，打开C项目时出现编译错误，核心报错为xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun，完整报错日志如下：

/Applications/CLion.app/Contents/bin/cmake/mac/bin/cmake -DCMAKE_BUILD_TYPE=Debug -DCMAKE_MAKE_PROGRAM=/Applications/CLion.app/Contents/bin/ninja/mac/ninja -G Ninja -S /Users/nikita/Documents/CLion/untitled -B /Users/nikita/Documents/CLion/untitled/cmake-build-debug

  The C compiler

    "/usr/bin/cc"

  It fails with the following output:

修复步骤 #

• 打开终端，执行命令安装/修复Xcode Command Line Tools：

  xcode-select --install
  

  执行后会弹出系统安装窗口，按提示完成安装。
• 若安装后问题仍存在，执行命令重置Command Line Tools路径：

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

  输入系统密码确认执行即可。
• 重启CLion，重新打开项目并尝试构建。

原因说明 #

MacOS系统更新后，Xcode Command Line Tools的关联路径可能被重置或损坏，导致CLion调用的/usr/bin/cc无法找到正确的编译工具链，触发错误。重新安装或重置路径即可恢复正常编译环境。
