💻 Code

Consumer module:

import a from 'my-library';
import b from 'my-library/foo';
import c from 'my-library/foo:virtual';
import d from 'my-library/bar';
import e from 'my-library/colon:here';

console.log({ a, b, c, d, e });

package.json for my-library:

{
  "name": "my-library",
  "version": "0.0.1",
  "type": "module",
  "exports": {
    ".": {
      "types": "./foo.d.ts",
      "default": "./foo.js"
    },
    "./foo": {
      "types": "./foo.d.ts",
      "import": "./foo.js"
    },
    "./foo:virtual": {
      "types": "./foo.d.ts",
      "default": "./foo.js"
    },
    "./*": {
      "types": "./*.d.ts",
      "default": "./*.js"
    }
  },
  "scripts": {
    "lint": "attw --pack; pnpm publint"
  },
  "dependencies": {
    "@arethetypeswrong/cli": "^0.14.1",
    "publint": "^0.2.7"
  }
}

every imported module is supposed to resolve, and then print:

{ a: 2, b: 2, c: 2, d: 2, e: 'two' }

(pnpm start in the consumer package in the repro link shows this)

🙁 Actual behavior

Errors, cannot find module

🙂 Expected behavior

align with JS, resolve the module

Additional information about the issue

No response

StackBlitz の repro と consumer パッケージの pnpm start から始め、次に、コロンを含む、表示された package.json の exports エントリを調べます。これらのパッケージサブパスに対する TypeScript のモジュール解決の動作を追跡し、JavaScript ランタイムの結果と比較します。5 つすべての import が解決され、期待される出力が生成されれば完了です。
