I have similar problem as had guy who asked "How do I resolve this error when installing the Forge source?". The question is resolved, but I can't find the mentioned fml/fml.py file. So please, where can I find it?

I have had no problems installing Forge, it installs fine, but when I try to run it I get an error message that some libraries couldn't be downloaded, and the game won't run.

I just need the path to this fml/fml.py file so I can edit it.

  • What version of Minecraft are you trying to install it on?

  • I'd suggest using Magic Launcher.

  • Why do you need that file? I've used Forge for both playing and developing mods and have never required that? Are you sure you need it and it's not an error or worse, and XY problem?

You have to download SRC version of the Forge and it's in there.
