【问题描述】：

我不知道为什么总是出现这个错误，尝试了很多次绕过它。也许谁知道解决方案并出现此错误？

app.module

NgxMapboxGLModule.withConfig(
      {token added..
          }),

包装

【解决方案1】：

来自ngx-mapbox-gl README的解决方案：

将此添加到您的 polyfill.ts 文件中 (https://github.com/Wykks/ngx-mapbox-gl/issues/136#issuecomment-496224634):

(window as any).global = window;

ngx-mapbox-gl 依赖于 sha.js，它调用在浏览器中不可用的“全局”（它是一个 Node.js 变量）。上面的代码将 'global' 填充为 'window'（在浏览器中可用）。 Angular 6 及更高版本为 Node.js 特定变量和库（加密、http 等）删除 webpack 的 polyfill 导致的更广泛问题的一部分

Angular 6 many Can't resolve errors (crypto, fs, http, https, net, path, stream, tls, zlib)
