macOS x86_64: indexing fails with TypeError: 'bytes' object is not an instance of 'str'

[amar1n]

On macOS Intel (x86_64), semble==0.1.4 installs successfully with:

uv tool install 'semble[mcp]==0.1.4'

But indexing a local repository fails both from CLI and MCP with:

• TypeError: 'bytes' object is not an instance of 'str'

Example command:

uvx --from 'semble[mcp]==0.1.4' semble search 'authentication' /path/to/local/repo

I also tried forcing Python 3.12, but got the same error.

I could not test newer versions because semble==0.3.4 is not installable on this machine due to tree-sitter-language-pack<1.6.3 not providing a compatible macOS x86_64 wheel.

This looks related to closed PR #128, which describes the same bytes vs str failure in parser.parse() with newer tree-sitter APIs.

Hello!

This is annoying, sorry about that. We might need to upgrade tree-sitter-language-pack if the owner does not supply pre-built wheels for this version specifically. Thanks for reporting, we'll look into it.

Hi Semble, is there an approximate date for a solution to this?
Thanks in advance!
