重复的"graphql"不能使用模块 [英] Duplicate "graphql" modules cannot be used

问题描述

我发现 graphql-js 库不允许依赖项也使用graphql.

I have found that the graphql-js library does not allow dependencies to also use graphql.

您将收到以下错误

重复的"graphql"模块不能同时使用，因为不同版本可能具有不同的功能和行为.来自一个的数据在另一个函数中使用的版本可能会产生混淆，并且虚假结果.

来自以下代码

const express = require('express');
const graphqlHTTP = require('express-graphql');
const { GraphQLSchema } = require('graphql'); 
// the module graphql-test-mod-obj-type' has 
// graphql as a depenedency
const myType = require('graphql-test-mod-obj-type');

const app = express();

const schema = new GraphQLSchema({ query: myType })

app.use('/graphql', graphqlHTTP({
  schema,
  graphiql: true
}));

app.listen(4000);

我创建了一个小型的repo和一个小型的公共npm软件包来演示这一点 repo-with-npm-dependency-on-graphql

I created a small repo and a small public npm package to demonstrate this repo-with-npm-dependency-on-graphql .

通过不使用graphql模块作为模块中的依赖项，可以很容易地解决此问题.但这肯定是一个问题吗?还是这是众所周知的事情?

This can be quite easily worked around by not having the graphql module as a dependency in the module. But surely this is an issue? Or is this a well known thing?
