我在 Angular 13 上，我正在尝试使用反射元数据包，但我得到奇怪的模块未找到错误：无法解析 '*\node_modules\reflect-metadata' 中的 'Crypto'。我已经尝试了堆栈溢出中列出的所有解决方案，但它对我不起作用。
我得到的实际错误 ./node_modules/reflect-metadata/Reflect.js:840:35-52 - 错误：找不到模块：错误：无法解析 'C:\Users\monke\Documents\Epicon\ 中的 'crypto' esb-ui\node_modules\reflect-元数据'
重大变化：webpack < 5 用于默认包含 node.js 核心模块的 polyfill。这已不再是这种情况。验证你是否需要这个模块并为它配置一个 polyfill。
如果你想包含一个 polyfill，你需要： - 添加一个后备 'resolve.fallback: { "crypto": require.resolve("crypto-browserify") }' - 安装 'crypto-browserify' 如果你不想要包含一个 polyfill，你可以使用这样的空模块：resolve.fallback: { "crypto": false }
这是我的包 JSON 依赖项。
