\nodejs\node_global";C:\src\flutter\bin;;C:\src\flutter\bin\mingit\cmd" was unexpected at this time.

This looks like part of a path variable, but it's not clear to me where this message is coming from. The next output at this point should have been from vcvars though, suggest that's what failed.

What happens if you run C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvars64.bat in a console?

Vcvars64.bat flashback without any reaction

Vcvars64.bat flashback without any reaction

I don't understand what this means. Please provide the output that was printed when you ran it.

[stuartmorgan]

This is basically the first error again, which means I still need an answer to my original question.

C:\src\flutter-desktop-embedding\example>"C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvars64.bat"
此时不应有 \nodejs\node_global";C:\src\flutter\bin;C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build;"。

C:\src\flutter-desktop-embedding\example>

That confirms that the error you are seeing is coming from your VS toolchain. You'll need to resolve that; it's outside the scope of Flutter.
