Javascript 解构导入失败，所有键未定义

我有一个

index.js

文件，该文件具有以下导出：

const mainPipe = require('./mainPipe')
const mongooseDriverPipe = require('./mongooseDriverPipe')
const neo4jDriverPipe = require('./neo4jDriverPipe')
const postgreDriverPipe = require('./postgreDriverPipe')
const redisDriverPipe = require('./redisDriverPipe')

exports.mainPipe = mainPipe
exports.mongooseDriverPipe = mongooseDriverPipe
exports.neo4jDriverPipe = neo4jDriverPipe
exports.postgreDriverPipe = postgreDriverPipe
exports.redisDriverPipe = redisDriverPipe

然后我导入：

const { mongooseDriverPipe } = require('../../pipes')
console.log(mongooseDriverPipe) // undefined

如果我：

const pipes = require('../../pipes')
console.log(pipes) // Logs an object with the above five keys
console.log(pipes.mongooseDriverPipe) // Logs the expected result

这也会返回未定义的

：

const test = require('../../pipes').mongooseDriverPipe
console.log(test) // undefined

我的所有路径都是正确的，我可以在不分解结构时看到导出对象及其所有关键点，但当我尝试分解结构时，所有分解的关键点总是
未定义

我不明白为什么这些键被解构为
未定义的
 尝试将这一行添加到index.js文件的顶部

module.exports = exports = {};

Require返回module.exports值

你可以在这里查看更多信息

如果愿意，也可以这样定义它们

module.exports = exports = {
    mainPipe : require('./mainPipe'),
    mongooseDriverPipe : require('./mongooseDriverPipe'),
    neo4jDriverPipe : require('./neo4jDriverPipe'),
    postgreDriverPipe : require('./postgreDriverPipe'),
    redisDriverPipe : require('./redisDriverPipe'),
}

看起来不错，您的文件中是否有任何循环依赖项？检查这个
