@saitonakamura there are many tests that require basic Unix tools. One simple way of getting all of them is to install Git for Windows and during the installation choose to include the tools on PATH, as described in https://github.com/nodejs/node/blob/master/BUILDING.md#windows.

If you don't want to reinstall Git for Windows or don't want the tools on PATH, you can open Git Bash and then either run the tests from there with winpty ./vcbuild.bat test, or use start to get a CMD window with the tools on path.

Oh, now I get what "basic unix tools" in this section meant. I will think how the wording can be improved to reflect that. I'm closing the issue in the meantime, thanks for the explanation @joaocgreis
