编译基板add-a-托盘失败

Question

当我遵循最新的基质教程add-a- palette时，我得到了编译错误。编译器抱怨绑定错误u128类型不满足事件。使用rustc版本:rustc 1.57.0-nightly (54bb4fec6 2021-10-08)

Answer 1

Substrate Node Template不能在任何版本的Rust编译器上编译。我建议:

1. executeinit.shscript inscriptsdirectory

2. 我这边的工作版本如下:

   stable-x86_64-unknown-linux-gnu

3. rustup default stable-x86_64-unknown-linux-gnu

应用这两个建议后，您应该能够编译源代码。
