Deno run resulting in loads of errors with third party module

[Tobi696]

(This is my first time using Deno, please don't flame me for beginner mistakes.)

When I run a simple file with no dependencies (e.g. console.log("Hello")), everything works fine.

As soon as I import a third-party library, I get loads of errors.

Script using third-party library:

import { opine, json } from "https://deno.land/x/[email protected]/mod.ts";

const app = opine();

app.listen(3000, () => {
    console.log('Server is listening on port 3000')
});

Output:

Found 34 errors.

[crowlKats]

You are using an extremely outdated version of opine

[shadowtime2000]

Yeah, use the latest which I believe is 1.1.0 with the same code and it works.

[Tobi696]

@crowlKats @shadowtime2000 Thank you, you solved my issue for opine module.

However, I still get 3 errors for using the bcrypt module:

import * as bcrypt from "https://deno.land/x/bcrypt/mod.ts";

console.log(await bcrypt.hash("toEncrypt"));

Found 3 errors.

[crowlKats]

Seems like that module is quite outdated

[Tobi696]

@crowlKats Yes, but I think it's the latest version available.

[shadowtime2000]

@Tobi696 I think what @crowlKats meant is that the module is very old and you probably shouldn't use it because it may be incompatible with latest deno versions.

[magician20]

@Tobi696 @shadowtime2000 I had the same problem ([email protected])
Is there any alternative for solving it or another third-party library?
Thanks.
Update:
as all mention top bcrypt quite outdated.
I tired different libs and all of them work good.

[bakasmarius]

I also got the same error and the only thing that helped me was running deno with --unstable flag.
