CLI error `This: command not found`

[splashsky]

I've installed lightningcss-cli globally for Node, for Bun, and even copied the binary from those directly to /usr/local/bin. Whenever I to execute the lightningcss binary, I get this error: /home/sky/.bun/bin/lightningcss: line 1: This: command not found I'm not sure what other steps to take, but I'd like to be able to use the project.
