打字稿错误在 tsconfig.json 中将模块更改为“umd”或“amd”时找不到模块“typescript-Collections”

Question

I am using VS17 Enterprise. I can easily import " typescript-collections " (as instructed on this page) if I had set my module option to commonjs in my tsconfig.json .

However, as soon as I change it to "umd" or "amd" , I get error (see the screenshot please) saying that Cannot find module 'typescript-collections' and therefore, the two variables queue and queue1 will be of type any . I have also attached my tsconfig.json .

Any help will be greatly appreciated.

Answer 1

As of today this problem with this package remains and my solution was to use es6 as my module

{
  "extends": "../tsconfig.json",
  "compilerOptions": {
    "outDir": "../out-tsc/app",
    "types": [],
    "module":"es6"
  },
  "exclude": [
    "test.ts",
    "**/*.spec.ts"
  ]
}

and then import the classes using the notation below -

import * as Collections from 'typescript-collections/src/lib';

It seems there is an issue with this dependency packaging.

Answer 2

I fixed a similar problem by explicitly specifying the moduleResolution compiler option.

{
    "compilerOptions":
    {
        "moduleResolution": "node"
    }
}

Apparently the moduleResolution is set to "node" automatically, if module is set to "commonjs" . The Typescript compiler seems to use another resolution strategy otherwise.

A post in a GitHub issue thread led me to this idea.
