substrate - 将尼克托盘添加到基材时出错

Question

我刚刚开始探索基板，我正在关注本教程（https://docs.substrate.io/tutorials/v3/add-a-pallet/）。

在步骤下实现尼克斯托盘配置特征- >将尼克斯添加到construct_runtime！宏。，我将 Nicks 托盘添加到我的运行时，如屏幕截图所示。

现在，当我运行时cargo check -p node-template-runtime，我得到了很多错误；

我尝试过的事情：
删除Cargo.lock文件，然后运行cargo check -p node-template-runtime​​.

PS：我只是从生锈和基材开始，所以如果我在这里问一些明显的问题，请原谅我。
