Question

我不知道为什么每次都会收到此错误，并尝试多次绕过它。也许谁知道解决方案并遇到了这个错误？

app.module

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

包装

    "ngx-mapbox-gl": "^3.0.1",
    "@types/mapbox-gl": "^0.51.4",
    "@mapbox/geojson-area": "^0.2.2",

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）：

（任意窗口）.global = window;

ngx-mapbox-gl依赖于sha.js，后者调用的“全局”在浏览器中不可用（这是一个Node.js变量）。上面的代码将'global'填充为'window'（在浏览器中可用）。 Angular 6和更高版本所引起的一系列问题中的一部分，它删除了针对Node.js特定变量和库（密码，http等）的webpack的polyfills

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