【问题描述】：
我遵循了Write a Pallet in its Own Crate 教程。
我用教程仔细检查了所有内容，但是当我cargo build --release 时，我收到 66 条错误消息。这些错误消息中的大多数类似于以下 2 条（更多详细信息请往下看）：
cannot find type `Pallet` in crate/scope
the trait bound `Runtime: frame_system::pallet::Congig` is not satisfied
我创建了一个错误日志。在 stackoverflow.com 上发布错误日志或这么多错误消息的最佳方式是什么？
Information that should be included in a bug report.
Executing build command: "/home/df/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/bin/cargo" "rustc" "--target=wasm32-unknown-unknown" "--manifest-path=/mnt/f/Etp/Substrate/tutorials/02/substrate-node-template/target/release/wbuild/node-template-runtime/Cargo.toml" "--color=always" "--release"
Using rustc version: rustc 1.55.0-nightly (24bdc6d73 2021-06-12)
显示的第一个错误如下：
errorm: expected one of: `Pallet`, `Call`, `Storage`, `Event`, `Config`, `Origin`, `Inherent`, `ValidateUnsigned`

338 | TestPallet: test_pallet::{Module, Call, Storage, Event<T>},
| ^^^^^^ `
因此我从第 338 行删除了 Module：TestPallet: test_pallet::{Module, Call, Storage, Event<T>},
如果我再次cargo build --release，我会收到 14 条错误消息，这些消息会在下面发布。你有什么想法，哪里出了问题？
