It's an issue with treesitter

Expected behavior

It works normally. In the past this configuration worked. I have not used this plugins for a month or so, was working fine last time. So there has been a breaking change recently.

Actual behavior

Running :TSUpdate give the following errors

Hey man! Those errors seem to be because of compiler versioning. Are you by any chance running on a mac? Macs are known to have old C++ standards and therefore have problems with compilation. If you are then you might wanna check out the workaround here. The nvim-treesitter guys are trying to figure out that problem so we'll have to resort to workarounds in the meantime unfortunately. On the off chance that you're not on a mac make sure that you're 100% running the latest clang/gcc version that your system allows.

If something still breaks then lemme know :)

I will close this issue because the workaround should be working for Mac users. Feel free to reopen the issue if the bug persists.
