Description

Language packages with exclusive tree-sitter parsers (type: 'tree-sitter' in grammars/mylanguage.cson) are unable to successfully install on Windows.

Failed to load a language-mylanguage package grammer
Cannot find module 'tree-sitter-mylanguage'

This can be observed with any community tree-sitter grammar package, such as:

• language-hclrs
• language-tree-test

Atom core packages seem to contain both the newer tree-sitter grammar file and older legacy (textmate) grammar file. It is possible that these core packages are defaulting to the legacy grammar when Windows users do not have node/node-gyp/tree-sitter installed? If so, how do you use tree-sitter grammars on windows?

• atom/language-c
  • grammars/c.cson
  • grammars/tree-sitter-c.cson
• atom/language-javascript
  • grammars/javascript.cson
  • grammars/tree-sitter-javascript.cson

Steps to Reproduce

1. Clone or Install language-hclrs to %userprofile%\.atom\packages
2. Launch Atom

Expected behavior:

Atom launches with the installed packages.

Actual behavior:

Failed to load package grammar. This has happened to me for every community package with a tree-sitter grammar.

Additional Information

Is it a prerequisite to install node, node-gyp (windows build tools) in order to use Atom tree-sitter grammars on Windows downloaded from atom.io/packages?
