我在试着升级铁 rust .我try 卸载(1.60.0)并重新安装.新版本为1.73.0.但当我运行rustc时，它会自动下载1.60.0并恢复到1.60.0.想知道我如何才能强制它使用新版本？

Rust is installed now. Great!
To get started you may need to restart your current shell.
This would reload your PATH environment variable to include
Cargo's bin directory ($HOME/.cargo/bin).
To configure your current shell, run:
source "$HOME/.cargo/env"
(base) % rustc -V
