Trouble while setting up Emacs for rust development

Hello, I'm completely new to Emacs / doomemacs, I was trying to setup my fresh installed doomemacs for rust dev. I did enable rust under :lang and lsp under :tools in my .doom.d/init.el. I also installed rust-analyzer server and added the Path to my .zshrc file. when I try to edit any .rs file I get following error: eldoc error:(file-missing Doing vfork No such file or directory). can anyone tell me how to fix that problem?

Emacs might not be picking up your shell environment variables. Try the emacs package “exec-path-from-shell”

Im did try installing exec-path-from-shell. I still getting some errors but I'm also not sure how my .zshrc should look like. I tried it in 2 ways: export PATH="$HOME/.emacs.d/bin:$PATH" export PATH="$HOME/.cargo/bin/rust-analyzer" than I get following error: eldoc error: (file-missing Doing vfork No such file or directory) Error while checking syntax automatically: (file-missing "Searching for program" "No such file or directory" "cargo") ​ export PATH="$HOME/.emacs.d/bin:$PATH" export PATH="$HOME/.cargo/bin/rust-analyzer" export PATH="$HOME/.cargo/bin/cargo Same error. export PATH="$HOME/.emacs.d/bin:$PATH" export PATH="$HOME/.cargo/bin:$PATH" error: eldoc error: (file-missing Doing vfork No such file or directory)

Looks like you don't have rust installed well. https://rustup.rs/ cargo should already be in the path from a good rust install. It's usually called from your .bashrc with something like - . "$HOME/.cargo/env"

Well my rust should be installed fine since I can use every command in my terminal also I developed rust in VsCode before. however to make sure there is no problem with my rust installation I did reinstall rust and put export PATH="$HOME/.cargo/bin to my .zshrc since the installer told me too. so from my point of view I just an emacs problem. Note that I'm running macOS 12.5 I don't have an bashrc, I think its because macOS uses zsh as default shell.

Ah its the old osx problem... osx doesn't give the graphical programs the same environment as the shell. I can't help much but here is an old fragment from like 10 years ago when I had to use osx briefly - (when (memq window-system '(mac ns)) (exec-path-from-shell-initialize) (exec-path-from-shell-copy-env "GOPATH") )

Temporary fix: try opening emacs from terminal so that it adopts the env vars

Well I've tested a bit and also tired to add the path to my .profile file but did not seem to work as well however I did replaced in my init.el under :lang rust with (rust +lsp) and that somehow seems to work
