Typescript ./node_modules/graphql/index.mjs 49:0-53:205 Can'；t重新导出指定的导出

我尝试使用

webpack4

将基于

typescript

的应用程序构建为

graphql

服务器

但会出现如下错误：

ERROR in ./node_modules/graphql/index.mjs 49:0-53:205

我今天使用角度通用SSR时运行的是完全相同的问题

我的解决方案是将这一行包含到我的webpack配置文件中的

externals

对象中

externals: {
  './dist/server/main': 'require("./server/main")'
},

对于那些在使用Angular 8和Apollo For Graphql时遇到相同问题的人来说，这是一个迁移指南，它让我的灵魂得到了一些启示：

在SSR模式下使用Apollo Angular时，我似乎也遇到了同样的问题。你在Edgaras Karka解决了吗？
