我是生锈的新手，制作了一个简单的生锈程序（hello world）。我从这里安装rust和Visual Studio- https://visualstudio.microsoft.com/downloads/并重新启动设备。但是，当我在rustc <path>命令提示符下键入时，我得到：
error: linker `link.exe` not found
|
= note: The system cannot find the file specified. (os error 2)
note: the msvc targets depend on the msvc linker but `link.exe` was not found
note: please ensure that VS 2013, VS 2015 or VS 2017 was installed with the Visual C++ option
error: aborting due to previous error
怎么了？
更新资料
我将系统路径更新为include C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools\VC\Tools\MSVC\14.22.27905\bin\Hostx64\x64，但是现在出现此错误：
error: linking with `link.exe` failed: exit code: …我已经在 python 2.7 中安装了 requests 模块，但是在导入它时给了我
import-im6.q16: not authorized `requests' @ error/constitute.c/WriteImage/1037
这是为什么？
