vscode c++ 编译可以通过 但是有红色波浪线的问题

1.command + p, 然后输入 >C/C++

选择 编辑配置(JSON)

然后在工作区会出现一个.vscode文件夹, 其中会有一个.json文件的配置

2.打开命令行 输入

gcc -v -E -x c++ -

会有以下的信息  

`ignoring nonexistent directory "/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/usr/include/c++/v1"ignoring nonexistent directory "/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/usr/local/include"ignoring nonexistent directory "/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/Library/Frameworks"#include "..." search starts here:#include <...> search starts here: /usr/local/include /Library/Developer/CommandLineTools/usr/include/c++/v1 /Library/Developer/CommandLineTools/usr/lib/clang/10.0.1/include /Library/Developer/CommandLineTools/usr/include /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/usr/include /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/System/Library/Frameworks (framework directory)End of search list.`

将上面的路径复制到刚刚的json文件中

如图

{       "configurations": [    {        "name": "Mac",        "includePath": [            "${workspaceFolder}/**",            "/usr/local/include/**",            "/Library/Developer/CommandLineTools/usr/include/c++/v1/**",            "/Library/Developer/CommandLineTools/usr/lib/clang/10.0.1/include/**",            "/Library/Developer/CommandLineTools/usr/include/**",            "/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/usr/include/**",            "/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/System/Library/Frameworks/**"        ],        "defines": [],        "macFrameworkPath": [],        "compilerPath": "/usr/local/bin/gcc-7",        "cStandard": "gnu11",        "cppStandard": "gnu++14",        "intelliSenseMode": "clang-x64"    }],"version": 4}

注意要在后面加 /**

然后红色波浪线就不会出现了。
