Ripgrep is not built for aarch64 - I'm guessing it should just not download and not fail the install.

Also it's annoying that yarn hides the helpful error output.

[bkeys]

Well there shouldn't be an issue compiling ripgrep for aarch64, is this an issue I need to make with ripgrep?

[roblourens]

No that's on me, we build our own for vscode. It sounds like that's just 64-bit ARM? I should be able to build that although I might not be able to test it.

[bkeys]

I am fine with testing it since I have the hardware

[roblourens]

Could you download the linux-aarch64 zip from here https://github.com/roblourens/ripgrep/releases/tag/0.8.1, unzip it, run rg from the command line, and tell me whether it seems to work?

[bkeys]

It seems to work

[bkeys@localhost Devel]$ ./rg
