“意外令牌导入”错误与Angular4 +通用+ NG

所以我升级到角4+只是让我可以利用通用软件包服务器端渲染引擎优化的目的。我实现了，在我现有的角度2+项目通过将其升级到角4+和。

只有一个区别，我使用NG-引导（V1.0.0-alpha.22）。但是，当我使用NPM运行启动-U-dev的运行的节点服务器我得到这个错误在NG-引导进口的关键字。

更新：此前我删除angular2，烤面包机，但后来我再次添加它只是为了确保它不是抛出同样的错误只是烤面包机模块。事实证明，无论是angular2，烤面包机和NG-引导抛出了同样的错误。

更新2：当我使用NG服务器上运行的服务器，它做工精细，用NG-引导和angular2，烤面包机与角度没有问题4+

有什么建议么？提前致谢。

对于那些试图了解该解决方案是什么，你基本上要使用白名单和angular2-toaster等模块给这个问题。

1. 如果使用角CLI中，使用ng eject创建webpack.config.js
2. 通过webpack-node-externals安装npm install依赖，并在webpack.config.js文件中添加以下行 const nodeExternals = require('webpack-node-externals'); module.exports = { ... target: 'node', externals: [nodeExternals({ whitelist: [ /^@ng-bootstrap\/ng-bootstrap/, /^angular2\-toaster/, ] })], ... }
