Failed to compile stdweb-derive

wischi-chr commented 5 years ago

I tried to clone the project and build at (according to readme) but it fails to compile - I'm also pretty new to rust so I've not really a clue how to fix that.

Did I miss something? Thanks and advance

Hi @wischi-chr

As it says here

error[E0554]: #![feature] may not be used on the stable release channel

the API uses features from rust that are not yet considered stable. Try using the nightly build toolchain. You can follow instructions here: https://doc.rust-lang.org/stable/book/2018-edition/appendix-06-nightly-rust.html#rustup-and-the-role-of-rust-nightly

Hi @ASalvail

Switched to rustc nightly now it works. Thank you for your help.
