gyp ignores MSBuild in path variable and chooses older version from .NET Framework

[voltmer1]

• Node Version: 14.8.0 and 6.14.7
• Platform: Microsoft Windows 10 Pro, 10.0.18362 Build18362, x64-based PC
• Compiler: MSBuild v 15.0.0
• Module: node-sass

I have set the system environment variable "PATH" with the path to MSBuild, but as gyp runs it finds this version on PATH, then later overrides it for a much older version within .NET Framework.

npm install node-sass -g
gyp info it worked if it ends with ok

That being said, this is not a node-sass issue. I get the same error when using any package that requires node-gyp. It refuses to use the MSBuild version over what is in the .NET Framework.
