我正在开发一个 Angular6+实体应用程序（代码库）。应用程序本身取决于：

"crypto-js": "^3.1.9-1",
"rdflib": "^0.19.0",
"solid-auth-client": "^2.2.6",
"stream": "0.0.2",
"webcrypto": "^0.1.1",
"zone.js": "^0.8.26"

我正在尝试使用以下方法删除 RDF 资源rdflib.UpdateManager.update()：

$rdf.UpdateManager(this.store).update(toBeDeleted, [], (uri, ok, message, response) => {
  if (ok) {
    console.log('DELETED')
  } else {
    console.warn(message)
  }
})

UpdateManager 你可以在这里找到更多关于 JSDoc和 rdflib.js 的介绍。

现在，使用 Firefox 63.0b12 (64-bit)，我不断收到以下错误，我认为这可能与访问WebCrypto API 应限制在安全来源（即https://页面）有关。使用 Opera 时会触发相同的错误。

我是否缺少 npm 依赖项？这个问题的根本原因是什么？

调用此代码时出现相同的错误：

import auth from 'solid-auth-client';

// for example in a button click handling, this gives me the error:
auth.logout();

使用 yarn、webpack 4 和 babel 7

依赖项：

"@material-ui/core": "^3.2.0",
"rdflib": "^0.19.0",
"react": "^16.5.2",
"react-dom": "^16.5.2"

“@trust/webcrypto”模块（0.9.2 版）处理其他模块动态加载的方式会在我的构建中触发警告：

WARNING in ./node_modules/@trust/webcrypto/src/algorithms/SupportedAlgorithms.js 84:22-60

听起来有点相关...

Dmitri Zagidulin 在这里回答了我的问题（以及我认为是解决方法的请求）：https ://github.com/anvilresearch/webcrypto/pull/80#issuecomment-431115569

该@trust/webcrypto模块仅用作后端的 NodeJS 模块。要将其从 webpack 捆绑中排除，可以将其替换为外部模块（由浏览器提供），例如：

externals: {
  '@trust/webcrypto': 'crypto',
  'text-encoding': 'TextEncoder',
}

PS：他还建议外部化text-encoding模块，这也是一个浏览器可用的模块。
