Linux系统，在配置VSCode的C语言开发环境时，会有头文件包含问题：

#include errors detected. Please update your includePath. Squiggles are disabled for this translation unit (/home/yty/Project/C/demo.c).

这是因为C语言配置文件c_cpp_properties.json中未包含依赖路径，解决方法：

• 找到本地头文件目录
  打开terminal，输入 gcc -v -E -x c++ -，结果如下：

  gcc 版本 9.1.0 (GCC) 
  COLLECT_GCC_OPTIONS='-v' '-E' '-mtune=generic' '-march=x86-64'
  /usr/lib/gcc/x86_64-pc-linux-gnu/9.1.0/cc1plus -E -quiet -v -D_GNU_SOURCE - -mtune=generic -march=x86-64
  忽略不存在的目录“/usr/lib/gcc/x86_64-pc-linux-gnu/9.1.0/../../../../x86_64-pc-linux-gnu/include”
  #include "..." 搜索从这里开始：
  #include <...> 搜索从这里开始：
  /usr/lib/gcc/x86_64-pc-linux-gnu/9.1.0/../../../../include/c++/9.1.0
  /usr/lib/gcc/x86_64-pc-linux-gnu/9.1.0/../../../../include/c++/9.1.0/x86_64-pc-linux-gnu
  /usr/lib/gcc/x86_64-pc-linux-gnu/9.1.0/../../../../include/c++/9.1.0/backward
  /usr/lib/gcc/x86_64-pc-linux-gnu/9.1.0/include
  /usr/local/include
  /usr/lib/gcc/x86_64-pc-linux-gnu/9.1.0/include-fixed
  /usr/include

• 添加到配置文件
  找到c_cpp_properties.json文件中的includePath，添加成如下

  "includePath": [
              "${workspaceFolder}/**",
              "/usr/lib/gcc/x86_64-pc-linux-gnu/9.1.0/../../../../include/c++/9.1.0",
              "/usr/lib/gcc/x86_64-pc-linux-gnu/9.1.0/../../../../include/c++/9.1.0/x86_64-pc-linux-gnu",
              "/usr/lib/gcc/x86_64-pc-linux-gnu/9.1.0/../../../../include/c++/9.1.0/backward",
              "/usr/lib/gcc/x86_64-pc-linux-gnu/9.1.0/include",
              "/usr/local/include",
              "/usr/lib/gcc/x86_64-pc-linux-gnu/9.1.0/include-fixed",
              "/usr/include"
          ]

  2

  9
        
        
  10
       
       

最后保存即可
