犯错误：C++ 中缺少包含内容脚本？
几分钟前我刚刚得到了如何编译这个脚本的帮助，但我已经成功地得到了错误。我只是 C++ 的初学者，不知道以下错误的含义或如何修复它。
这是有问题的脚本。我已经阅读了一些用户的评论，建议他们更改了 #include 部分，但这似乎正是脚本所具有的内容，查看此评论。

感谢大家的帮助
I just got help in how to compile this script a few mintues ago on SO but I have managed to get errors. I am only a beginner in C++ and have no idea what the below erros means or how to fix it.
This is the script in question. I have read the comments from some users suggesting they changed the #include parts but it seems to be exactly what the script has, see this comment.

Thanks all for any help

该错误消息表明编译器找不到您尝试包含的内容，即
-I标志来指定包含目录（这些目录不是递归的）。目前，您设置以下包含目录：
您需要找到
QWebView在系统上的位置，并将包含路径添加到命令行（或将 QWebView 安装到上述目录之一）。一般注意事项：当您遇到很多这样的错误时，请重点关注前一两个错误。后面的错误（例如
“QWebView”尚未声明）可能会通过修复丢失包含错误来解决。The error message indicates that the compiler cannot find what you're trying to include, i.e.
<QWebView>. The way to tell the compiler where to look is with the-Iflag, to specify include directories (these are not recursive).Currently, you set the following include dirs:
You need to find where
QWebViewis located on your system, and add the include path to the commandline (or install QWebView into one of the above dirs).General note: When you get a lot of errors like this, focus on the first one or two. The later errors (such as
‘QWebView’ has not been declared) will probably be solved by fixing the missing-include error.看起来必须在代码中提供名称空间。阅读命名空间。
没有可用的类型定义，可能会缺少包含。
Looks like namespaces have to be provided in the code. Read on namespaces.
No type definition available, can be missing include.
