You'll probably need to make your environment variables visible to Emacs. The example setup uses the https://github.com/purcell/exec-path-from-shell package for that, see https://github.com/rksm/emacs-rust-config/blob/master/init.el#L126.

i already installed. and other bash can execute.

[rksm]

Is emacs able to resolve the paths when you eval (Alt-:) the following expressions?

(executable-find "cargo")
(executable-find "rustc")
(executable-find "rust-analyzer")

[rksm]

Looking at your error messages, it seems that is not the issue. But

[ERROR rust_analyzer::reload] failed to load workspace: "cargo" "--version" failed, exit code: 1
stderr:
error: no override and no default toolchain set

looks like you need to set a default rust toolchain, e.g.

$ rustup default stable
