Pallet-Nicks Tutorial - error: unexpected token

[Inux131]

Hi,

added dependencies & features in the Cargo.toml then: $ cargo build --release

how can I fix this?

A lot of errors are occurring:

and so on...

I think what you are doing is replacing the entire construct_runtime with

/     {
  327 | |         /* --snip-- */
  328 | |         Balances: pallet_balances,
  329 | |
  330 | |         /*** Add This Line ***/
  331 | |         Nicks: pallet_nicks,
  332 | |     }

You are just meant to add this line to it

     Nicks: pallet_nicks,

So it should look like this:

  construct_runtime!(
    pub enum Runtime where
        Block = Block,
        NodeBlock = opaque::Block,
        UncheckedExtrinsic = UncheckedExtrinsic
    {
        System: frame_system,
        RandomnessCollectiveFlip: pallet_randomness_collective_flip,
        Timestamp: pallet_timestamp,
        Aura: pallet_aura,
        Grandpa: pallet_grandpa,
        Balances: pallet_balances,
        Nick: pallet_nicks,   <== Add this to it.
        TransactionPayment: pallet_transaction_payment,
        Sudo: pallet_sudo,
        // Include the custom logic from the pallet-template in the runtime.
        TemplateModule: pallet_template,
    }
);

Hope this helps

Hey,

thank you very much, it helped. At first it showed another error. I closed the Terminal and reopened. Then the next Error was:

`~/substrate-node-template$ cargo check -p node-template-runtime Compiling node-template-runtime v4.0.0-dev (/home/robert/substrate-node-template/runtime) warning: unused doc comment --> runtime/src/lib.rs:251:1	251	/// Add this code block to your template for Nicks:	^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ rustdoc does not generate documentation for macro invocations

I assume, that /// and // are comments and can be put at will.

Thanks so far for your help!
