I'm sure that it's my problem but,I don't know how to fix it. The problem is When compiling , it said :

For more information about this error, try `rustc --explain E0658`.
error: could not compile `uefi`.

But I don't know where to add the feature , or there is something wrong with my rustc version ?

rustc 1.45.0-nightly (56daaf669 2020-06-03)

You need to update your compiler to the latest nightly

It's the wrong of Rustup version , you have to update the nightly version and change the Rust-tool_chain
