Hi there,  
I would like to configure my editor but I cannot find the path to `mojo-lsp-server` in my Pixi shell. I only have `mojo`.  
Thanks for your help.

Make sure you’ve installed the `mojo` package, which includes both the `mojo-compiler` base package as well as the LSP and debugger. The default `max` package does not include these, to save size on distribution of MAX and models, so if using `max` you’ll also need to add `mojo`.

Once that package is installed, `mojo-lsp-server` should be installed in `.pixi/envs/default/bin` in your Pixi environment.

Hi @BradLarson  
It works, thank you.  
Sort of… I am encountering a huuge memory leak of about 1 Go / minute. Am I missing anything?  
I am using Mojo 0.25.6.1 (4a162eab)  
Thanks again.

If you have a reproducer for that memory leak, please [file an issue](https://github.com/modular/modular/issues) and we’ll look into it. We’ve been trying to fix all of these that have come up, but if there’s a new regression we’d want to get to the bottom of it.
