javascript - Angular 库导入 *

Question

所以我在库中使用的模块之一是 sha256。必须这样导入:

import sha256 from 'sha256';

现在我读到了这个问题: Errors when using MomentJS in Angular Typescript library

编译时需要采取不同的做法:

所以一开始我把它改成了:

import * as sha256_ from 'sha256';
const sha256 = sha256_;

但是这些引发了相同的错误:

ERROR: Cannot call a namespace ('sha256')
An unhandled exception occurred: Cannot call a namespace ('sha256')

然后我尝试编辑我的 tsconfig.json:

  "angularCompilerOptions": {
    "allowSyntheticDefaultImports": true,
    "fullTemplateTypeCheck": true,
    "strictInjectionParameters": true
  }

但是没有任何成功。

谁能告诉我如何使用这样的导入正确构建我的库？

编辑

我还将它添加到 compilerOptions 中:

    "compilerOptions": {
    "outDir": "../../out-tsc/lib",
    "target": "es2015",
    "declaration": true,
    "inlineSources": true,
    "allowSyntheticDefaultImports": true,
    "types": [],
    "lib": [
      "dom",
      "es2018"
    ]
  },

试试这个..

npm install --save @types/sha256

然后

import sha256 from 'sha256';

or

import * as sha256_ from 'sha256';
