TypeError: core.initializeAsyncOps is not a function

When I follow the tutorial, this error occurs during runtime：

$ cargo run
   Compiling runjs v0.1.0 (D:\projects\rust\runjs)
    Finished dev [unoptimized + debuginfo] target(s) in 3.12s                                                                                                                                   
     Running `target\debug\runjs.exe`

When I remove initializeAsyncOps, calling op_write_file will report this error：

cargo run

    Finished dev [unoptimized + debuginfo] target(s) in 4.70s                                                                                                                                   
     Running `target\debug\runjs.exe`

    at Object.writeFile ([runjs:runtime.js]:22:29)
    at file:///D:/projects/rust/runjs/example.js:11:13

How should I solve this problem? This is my code.

Just update deno_core to the latest version, no need to call initializeAsyncOps.
