很遗憾，我在文档中找不到任何内容.因此，在尝试解析绝对路径的导入时，我跟踪了由编译器(TypeScript 2.5.2)执行的文件系统访问.

Unfortunately I couldn't find anything on that in the docs. So I traced the file system accesses performed by the compiler (TypeScript 2.5.2) when trying to resolve an import of an absolute path.

结果是 /始终引用文件系统根目录.不管compilerOptions(例如rootDir，rootDirs或baseUrl).

The result is that / always refers to the file system root. Regardless of compilerOptions like rootDir, rootDirs or baseUrl.
