错误：板条箱“sp_io”中存在重复的语言项目

问题描述 投票：0回答：3

我正在构建一个基于基板的项目，当我运行

cargo build --release
时，我看到一些错误。 
runtime

有人可以帮我吗？

我的解决方案是将其添加到

lib.rs
：

#![cfg_attr(not(feature = "std"), no_std)]

我认为您应该再次取消注释运行时配置中的自定义托盘之一，例如

Template:pallet-template::{Pallet,Call,Storage,Event<T>}
和
cargo check
，以便您可以检查导致错误的修改托盘。或者您可以显示定制托盘的所有 Cargo.toml 吗？我会帮助你的。

通常这意味着您在上游拥有相同底层依赖项的多个版本。第一步，确保所有 

cargo.toml
文件具有相同的 semver 兼容版本（最好完全相同）。然后执行 
cargo clean
并 remove 
cargo.lock
文件。尝试再次构建。如果仍然无法正常工作，您可能需要通过 cargo update -p foo -p bar
手动更新特定软件包
