当您得到这种类型的链式错误时，很可能您复制了错误的东西，不小心删除了一些重要的元素，例如逗号、分号等等。

确保您没有删除任何重要的内容，然后再试一次。如果不是这样，那就检查这一行，我认为这是关键：

error: unexpected token --> /home/robert/substrate-node-template/runtime/src/lib.rs:326:2 
| 326 | / { 327 | | /* --snip-- / 328 | | Balances: pallet_balances, 329 
| 
| 330 | | /** Add This Line ***/ 331 | | Nicks: pallet_nicks, 332 | | }
