Description of issue

Help Needed. The past few weeks facing errors while trying to install brew install neovim --HEAD
The output is the following:

User source builds are explicitly not supported. HEAD source builds are doubly unsupported, simply because upstream can break HEAD at any time.

Your best bet is to look at the full build logs to see if you can figure out what needs fixing, and/or asking upstream. The output you posted points you to where the log files are located:

As @gromgit says, HEAD builds can break for any reason. In this case, try:

brew uninstall --force tree-sitter
brew install --HEAD tree-sitter
brew install --HEAD neovim

[Trid-collab]

@carlocab Thank you very much.It worked. A newbie question- is it necessary to do brew install --HEAD tree-sitter for the nigthly build of tree-sitter or only the stable version of tree-sitter brew install tree-sittee would do for installing the neovim nightly through brew install --HEAD neovim.

[gromgit]

Your build errors were with the stable tree-sitter, so it's a good bet that HEAD neovim is using functionality that's only available on HEAD tree-sitter.

In any case, the primary source of truth for HEAD builds is always upstream (the developer), not Homebrew (the packager).

@gromgit @carlocab Thank you very much for the explantation and the help
