rust-script fails to execute in nix #55

Closed DavidDTA closed 1 year ago

DavidDTA commented 2 years ago

I've installed rust-script via nix like so:

nix-shell -p rust-script

In that shell, I can run the rust-script executable:

[nix-shell:~]$ rust-script --version
rust-script 0.20.0

However, if I attempt to provide a file, I get an error:

[nix-shell:~]$ rust-script ~/myscript
error: No such file or directory (os error 2)

The same problem happens with the --expr option:

[nix-shell:~]$ rust-script --expr "3"
error: No such file or directory (os error 2)

Here is a full trace:

@DavidDTA Could you retry with the latest version - just released version 0.23.0? If the problem persists, could you perhaps use strace to see where the problem is (which file or directory does not exist)?

DavidDTA commented 1 year ago

I'm afraid I no longer have a nix setup, and won't be able to retry

bcdroid commented 1 year ago

I had had the same problem, but it appears to now work without problems with both 0.22.0 and 0.23.0. Thank you!

@DavidDTA & @bcdroid: Thanks!
