I would like to download Fuchsia's source code.
I entered curl -s "https://fuchsia.googlesource.com/fuchsia/+/HEAD/scripts/bootstrap?format=TEXT" | base64 --decode | bash
that I found on fuchsia.dev.
I got ''base64'' is not recognized as an internal or external command, operable program or batch file.
I downloaded base64 tools without success.
What should I do to make this command work?
