Hello, I just installed roc (windows/wsl) , am trying to run HelloWorld and getting 'Error: Os { code: 1, kind: PermissionDenied, message: "Operation not permitted" }' . roc version : roc nightly pre-release, built from commit 010aed8 on Mi 08 Mai 2024 09:01:56 UTC
A message was moved here from #beginners > I can't figure out why using foo = []
doesn't work by Hristo.
Hi @_boris_,
To run hello world Roc will download code into /home/your_username/.cache/roc.
Can you try mkdir /home/your_username/.cache/roc
and tell me if that also produces a permission denied error?
Anton said:
mkdir /home/your_username/.cache/roc
Thanks @Anton , /home/your_username/.cache/roc already existed and unfortunately the error persists
Can you tell me the size of the .cache/roc folder (du -sh .cache/roc)?
du -sh /home/boris/.cache/roc
106M /home/boris/.cache/roc
Thanks, that looks good. To figure out what's going wrong you'll need to build the compiler from source:
