Help! I can't install the toolchain

Hi, I just got my Daisy Seed, and I can’t seem to use the toolchain. I’ve downloaded and installed everything, but whenever I run the “build_all” task, this pops up:

I really don’t get what’s happening here. Could anyone offer some tips? Thanks!

I don’t think regular Windows cmd.exe is compatible with most posix-style commands and syntax (e.g. the -p flag with the mkdir command). VS Code should use your default terminal selection for tasks, and if you switch it to git bash (which you can find here if you don’t already have it), errors like that should be alleviated.
