I am developing within a container. How does this error manifest differently, and how do I correct it?

Within a container, ensure Rust is installed within the *container image* itself. The host system's Rust installation is irrelevant. Include the Rust installation commands (usually using `rustup`) in your Dockerfile or container configuration. Also, carefully manage PATH variables *within the container*. Use a `USER` directive in your Dockerfile after Rust is installed to change the current user if necessary; verify PATH after changing user.
