1. npm install --save react react-dom

⠄ Installing node dependencies…

I get the message below, i was wondering what to do about this and maybe this the cause that i fail to execute the tutorial?! , besides my little knowledge. just was interested in how to apply web visual design with icp dfinity in combination with react. if react fails. is it possible to make a tutorial without react but still possible to make something as a webdesigner?

npm WARN contacts\_assets@0.1.0 No repository field.

npm WARN contacts\_assets@0.1.0 No license field.

I really do all the steps as is written down but i keep getting some message about wasm.

Details: ReplicaError { reject\_code: 3, reject\_message: “IC0304: Attempt to execute a message on canister ryjl3-tyaaa-aaaaa-aaaba-cai which contains no Wasm module” }
