Last night, I have one the Rust project cannot compile itself and 100% sure it’s working fine in the past days. No change anything about it. What’s happened?
According to the screenshot content, it should be relevant to the system environment as bellow:

Just as expected! when I was opened the XCode tools, it told me that need to install another component,
sudo xcode-select --install
Typing in password of local machine and then the program will be installing process for XCode tool:

That’s it. back to project and then with ” cargo check “, it’s working fine.
Next, with a “cargo build ” command to build the project,

Finished!
Good Luck ~
