检测到 #include 错误。请更新 includePath。已为此翻译单元(/Users/zhoujianwen.cn/works/github/test/test.cpp)禁用波形曲线。C/C++(1696)
无法打开 源 文件 “wchar.h” (dependency of “iostream”)C/C++(1696)
g++ -v -E -x c++ -
输出的路径信息
按下command + shift + p ， 选择C/C++编辑配置(JSON)
将刚才输出的路径信息拷贝到c_cpp_properties.json

保存即可生效。
如何编译和调试代码？
首先要配置好c_cpp_properties、launch、settings、tasks等 json 文件，其中 settings 是自动创建的，不用管它。
command + shift + p
c_cpp_properties.json
自动在当前目录下创建.vscode 文件夹，并创建c_cpp_properties.json，而其它的json配置文件创建方法类似，当然也可以手动创建，然后打开文件点击配置自动构建。
