Hello, I'm currently in internship and I have to do a project with the elrond blockchain, I started to follow the doc, spanking the tutorials and etc.. to understand the development environment. but I get this error after doing an erdpy contract build from the tuto https://docs.elrond.com/developers/tutorials/crowdfunding-p1/#step-3-the-build Here is my error: error[E0554]: `#![feature]` may not be used on the stable release channel --> /home/aimeric/elrondsdk/vendor-rust/registry/src/github.com-1ecc6299db9ec823/elrond-wasm-derive-0.31.1/src/lib.rs:4:12 | 4 | #![feature(proc_macro_quote)] | ^^^^^^^^^^^^^^^^ For more information about this error, try `rustc --explain E0554`. error: could not compile `elrond-wasm-derive` due to previous error warning: build failed, waiting for other jobs to finish... error: build failed CRITICAL:cli:Build error: error code = 101, see output. By the way, I tested the build with the nightly and stable version and I still get the same error. Do you have any idea why I have this problem and how to solve it? And also if you don't mind, could you explain to me what does proc_macro_quote?
