您似乎没有正确使用该选项.语法为-I directory，根据Microsoft文档，

It looks like you're not using the option correctly. The syntax is -I directory, and according to the Microsoft documentation, to add more than one directory, you must use this option more than once. If you have faithfully reproduced the actual command-line you're using, then you have got -I directory -I directory directory directory directory, so several of your include directories are ignored.

假设您希望所有这些目录都包含在include路径中，则正确的语法为:

Assuming you want all of these directories in the include path, the correct syntax is:

-I "C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include\sys"
-I.
-I "C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include\sys"
-I "C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Include"
-I "C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include"

请注意在每个目录之前的-I的使用，其中包括 ..

Note the use of -I before each directory, including . .
