Unable to import dependency in deno dep.ts file in another class

问题

I have mentioned the dependency in dep.ts file and I want to import the reference in another file. But I am getting the following error. Please help me to resolve. I was following the link as mentioned below.

https://deno.land/manual/linking_to_external_code#it-seems-unwieldy-to-import-urls-everywhere

My simple code goes here.

dep.ts

export {
    log
  } from "https://deno.land/std/log/mod.ts";

Test3.ts

import { log } from "./dep.ts";

export class Test3 {

    public show() {
        log.debug("Exploring deno ...");

    }

}

const test = new Test3();
test.show();

While executing the command deno run Test3.ts, I get the following error.

error: Uncaught NotFound: Cannot resolve module "file:///C:/javascriptdev1/deno-test1/deps.ts" from "file:///C:/javascriptdev1/deno-test1/Test3.ts"

回答1:

error: Uncaught NotFound: Cannot resolve module

That error means you're importing the wrong file (does not exist).

You're importing deps.ts instead of dep.ts

Aside from that, what you want is to:

export * as log from "https://deno.land/std/log/mod.ts";

// you can have other exports too
export {
  assert,
  assertEquals,
  assertStrContains,
} from "https://deno.land/std/testing/asserts.ts";

Otherwise you'll get:

Module '"./deps"' has no exported member 'log'

回答2:

You're importing from "deps.ts" but the file name is "dep.ts". Make sure everything is spelled correctly.
