MinGW 安装并运行。环境变量已检查并正确，但 gcc -v 或 g++ --version 不起作用

Question

我正在尝试安装并检查 MinGW 以便在 MSVSCode 中进行调试。

我有运行 MinGW 安装管理器 (mingw-get) GUI 来安装 MinGW。我安装了以下内容：

mingw-developer-toolkit-bin
mingw32-base-bin
mingw32-gcc-g++-bin
mingw32-gcc-objc-bin
msys-base-bin

并且我已经验证它正在工作，如下所示：-

C:\MinGW\bin>g++ --version
g++  <MinGW.org GCC-8.2.0-5> 8.2.0

用户变量路径：-

系统变量路径：-

C:\ProgramData\Oracle\Java\javapath;c:\Program Files (x86)\Intel\iCLS Client\;c:\Program Files\Intel\iCLSClient\;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files\Intel\Intel(R) Management Engine Components\DAL;C:\Program Files\Intel\Intel(R) Management Engine Components\IPT;C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\DAL;C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\IPT;C:\Program Files\Microsoft SQL Server0\Tools\Binn\;C:\Program Files (x86)\Windows Kits.1\Windows Performance Toolkit\;C:\Program Files\MATLAB\R2016b\bin;C:\Program Files (x86)\MySQL\MySQL Utilities 1.6\;C:\Program Files\nodejs\;C:\Program Files\CMake\bin;C:\Program Files\Microsoft VS Code\bin; C:\MinGW\bin;

如果我输入

C:\Users>gcc -v

我收到错误消息

'gcc' is not recognised as an internal or external command, operable program or batch file.

但是，如果我输入

C:\Users>set PATH=C:\MinGW\bin;%PATH%

然后我写

C:\Users>gcc -v

然后我得到...

Using built-in specs.
COLLECT_GCC=gcc

COLLECT_LTO_WRAPPER=c:/mingw/bin/../libexec/gcc/mingw32/8.2.0/lto-wrapper.exe

gcc version 8.2.0 (MinGW.org GCC-8.2.0-5)

但是，只要此命令控制台 window 处于打开状态。

我的操作系统是 Windows 7 Home Premium Service Pack 1 64 位操作系统。

有没有什么方法可以让它工作，这样我就不需要每次都写 set PATH，这样它就可以在 MSVSCode 中工作了？

非常感谢任何帮助建议

除非是拼写错误，否则问题中粘贴的环境变量似乎包含额外的 space:

...C:\Program Files\Microsoft VS Code\bin; C:\MinGW\bin;
                                          ^

这使得系统搜索（不存在的）路径“C:\MinGW\bin”而不是正确的 "C:\MinGW\bin"。

MinGW installed, and works. Environment variables checked, and correct, however gcc -v or g++ --version doesn't work
