Module imports function '__wbg_now_2e07eedfb4ac9dbe' from '__wbindgen_placeholder__' that is not exported by the runtime

Hi, @Severin.
Nice to meet you.

I am a new developer fascinated by internet computer.
I’m implementing json-web-token(JWT) in Canister using Rust.

The project compiled successfully, but this error occurred during canister deployment.

Error: Failed while trying to deploy canisters.
Caused by: Failed while trying to deploy canisters.
  Failed while trying to install all canisters.
    Failed to install wasm module to canister 'local_user_index'.
      Failed during wasm installation call: The replica returned a replica error: Replica Error: reject code CanisterError, reject message Wasm module of canister bkyz2-fmaaa-aaaaa-qaaaq-cai is not valid: Wasm module has an invalid import section. Module imports function '__wbg_now_2e07eedfb4ac9dbe' from '__wbindgen_placeholder__' that is not exported by the runtime., error code None
