tree-sitter executable not found

[boydkelly]

Im using

NVIM v0.5.0-dev+1170-g691a72bb6
Build type: RelWithDebInfo
LuaJIT 2.1.0-beta3

in a Fedora 34 container (neovim nightly and tree-sitter installed from copr repo)

running checkhealth I get the message:

WARNING:tree-sitter executable not found (parser generator, only needed for :TSInstallFromGrammar, not required for :TSInstall)

I also have npm tree-sitter and nmp tree-sitter-cli installed.

I'm not even sure if this is redundant or not. Just that it was working recently in F33 container.

I also have a lot of these messages in checkhealth:

The following errors have been detected:
 - ERROR: yaml(highlights): /usr/share/nvim/runtime/lua/vim/treesitter/          language.lua:33: ABI version mismatch for /var/home/bkelly/.local/share/        nvim/site/pack/packer/start/nvim-treesitter/parser/yaml.so: supported           between 13 and 13, found 11
 - ERROR: yaml(locals): /usr/share/nvim/runtime/lua/vim/treesitter/              language.lua:33: ABI version mismatch for /var/home/bkelly/.local/share/        nvim/site/pack/packer/start/nvim-treesitter/parser/yaml.so: supported           between 13 and 13, found 11

Any suggestions here? Thank you very much!

Ok all solved here. It seems that yarn was causing the problem. It seems yarn v2 doesn't support global package install. I removed yarn and reinstalled treesitter with npm and checkhealth is fine. I'm still left with the question as to what the fedora tree-sitter package provides here. Its a dependency of neovim, but is it being replace by npm?

[theHamsta]

Yarn and npm support global install. The binaries are not added to path automatically. You need to reinstall the yaml parser to get the new ABI

[boydkelly]

I did reinstall all the parsers. But yarn v2 does not support global install. ;) See: yarn global install issue
This is what really led to my problems. I ended up recreating my container etc. and doing headstands, before I finally figured out.

Anyway all is working fine now.

But I'm still trying to figure out the relationship and/or difference between the tree-sitter rpm and npm packages. Without the npm package I will get the executable not found error although the Fedora treesitter package is installed.

Still getting

## Installation

in `checkhealth.

Manual install fails:

@horseinthesky the system npm does usually not work with global installations. You probably also don't want to install npm packages as root. You can download download tree-sitter from here: https://github.com/tree-sitter/tree-sitter/releases or via cargo install tree-sitter or using brew, or brew install npm. I you need more help, feel free to open an issue at upstream tree-sitter. Please note that you do not need this binary for using nvim-treesitter (:TSInstall will use the C files directly without the need of tree-sitter CLI)

[boydkelly]

Another possibility is to install nvm. It will install in your home and you will not have this issue.

@theHamsta @boydkelly
I wonder why it even yells that there is no executable if it doesn't need it?! It was working perfectly fine severa days ago.

[theHamsta]

It will always report this in healthcheck when it's not there. However, you will only need it for some parsers that require :TSInstallFromGrammar

u need install tree-sitter-cli

yarn global add tree-sitter-cli

[LeoniePhiline]

This is also true for cargo users:

cargo install tree-sitter-cli (instead of cargo install tree-sitter): https://github.com/tree-sitter/tree-sitter/tree/master/cli

[hopezh]

This is also true for cargo users:

cargo install tree-sitter-cli (instead of cargo install tree-sitter): https://github.com/tree-sitter/tree-sitter/tree/master/cli

Thanks for the suggestion, which helped me got rid of that warning after I installed rust+cargo and then tree-sitter-cli.
