cargo run Failed to fetch tree-sitter grammars

[bogdan-ov]

Hi! I want to play with the helix code, but when I run cargo run (also build and build --release) command in the root dir, I get this output:

   Compiling helix-term v23.10.0 (***/helix/helix-term)
error: failed to run custom build command for `helix-term v23.10.0 (***/helix/helix-term)`

Caused by:
  process didn't exit successfully: `***/helix/target/debug/build/helix-terme6ff343e52fec56a/build-script-build` (exit status: 101)
  --- stderr
  thread 'main' panicked at 'Failed to fetch tree-sitter grammars: data did not match any variant of untagged enum GrammarSource
  in `grammar.source`
  ', helix-term/build.rs:5:26
  note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

How can I fix this?

What I have:

• arch linux 6.7.4
• cargo 1.70.0
• also I have gcc compiler (as I know treesitter needs some kind of C compiler)

I'm sorry if this is a stupid question, but I really have no idea how to fix this...
Thank you in advance!

Do you have any custom config in ~/.config/helix/languages.toml, .helix/languages.toml or modifications to the languages.toml in the root of the repository?

[bogdan-ov]

Yes, I have only custom ~/.config/helix/languages.toml, I haven't modified the source code in any way
Should I delete my languages.toml from config dir? (or just move/rename it)

[the-mikedavis]

Yeah, the error message is saying that there's a [[grammar]] entry with an invalid source field in the language config. If you move or delete that file the build should work

[bogdan-ov]

Yea, this helped! Thank you very much!
