Nx.dev错误：无法在webpackEmptyContext

问题描述

我使用nx.dev monorepo，节点插件和阿波罗联盟
我使用CLI创建了一个库：nx generate @ nrwl / node：library acl-directive
一切看起来都很不错，但是当我尝试使用require（__ dirname +“ /assets/roles.json”）文件时，
会给我控制台错误，
Error: Cannot find module 'C:\Users\Desktop\monorepo\dist\apps\apollo/assets/roles.json' 问题是，当我使用polyrepo时，一切正常，但是在此monorepo中，一切都崩溃了，我不知道原因。
我的设置和代码：

// libs/acl-directive 

import { SchemaDirectiveVisitor,AuthenticationError } from 'apollo-server'
import { defaultFieldResolver } from 'graphql'
import * as fs from "fs"

// worked with this approche
// const data = fs.readFileSync(__dirname + '/assets/roles.json','utf8')
// const roles = JSON.parse(data)

// not work: error
const roles = require(__dirname + '/assets/roles.json')

export class aclDirective extends SchemaDirectiveVisitor {

  // directive on FIELD_DEFinitioN
  visitFieldDeFinition(field){

    const { resolve = defaultFieldResolver } = field

    field.resolve = async (...args) => {
      
      const [,context] = args

      // get role from context.user
      const user = JSON.parse(context.user)
      const { role } = user

      // get permissions for that specific role (user,vip,admin...)
      const permissions = roles[role]

      // check if in permissions we have field.name  (users,me,...)
      if (!permissions.includes(field.name)) throw new AuthenticationError(`Can Not Access To ${field.name}`)

      // allow to access to that resolver
      return await resolve.apply(this,args)
    }
  }
}

// libs/acl-directive/tsconfig.lib.json
// also i add this two lines to apps/todo/tsconfig.app.json
// and in tsconfig.base.json
...
"resolveJsonModule": true,"esModuleInterop": true
...

完全错误：
