【问题描述】：

Vue-Apollo 3.04 的发行说明声明现在支持 Apollo Client 3。正如 Apollo Client 3 的文档所声明的那样，ApolloClient、InMemoryCache、HttpLink 现在都在一个 @apollo/client 包中 - 不像以前的单个包。

https://github.com/vuejs/vue-apollo/releases/tag/v3.0.4

https://www.apollographql.com/docs/react/migrating/apollo-client-3-migration/

但是，Vue-Apollo (apollo-client -> @apollo/client ?) 的文档中没有关于如何应用新更改的更改。此外，Apollo Client 3 文档指出，对于 Vue，您必须从 @apollo/client/core 导入 ApolloClient

所以我尝试了自己的方式，但我的导入似乎失败了。我从npmm run serve 收到这些错误消息。似乎他想导入一些reactstuff。

     ERROR  Failed to compile with 8 errors                                                                                                             20:25:20
This dependency was not found:

* react in ./node_modules/@apollo/client/react/context/ApolloConsumer.js, ./node_modules/@apollo/client/react/context/ApolloContext.js and 6 others

To install it, you can run: npm install --save react

vue-apollo.js（来自有效的旧项目）

---

import Vue from 'vue'
import  ApolloClient  from 'apollo-client'
import  HttpLink  from 'apollo-link-http'
import  InMemoryCache  from 'apollo-cache-inmemory'
import VueApollo from 'vue-apollo'

vue-apollo.js（带有新的 apollo 客户端 3）

---

import Vue from 'vue'
import  ApolloClient  from '@apollo/client/core'
import  InMemoryCache  from '@apollo/client/cache'
import  HttpLink  from '@apollo/client'
import VueApollo from 'vue-apollo'

package.json

     "dependencies": 
    "@apollo/client": "^3.1.3",
    "core-js": "^3.6.5",

    "subscriptions-transport-ws": "^0.9.18",

如何用vue apollo正确导入新的apollo client 3？

【参考方案1】：

好吧，休息后我尝试了这个，它成功了。

vue-apollo.js

---

import Vue from 'vue'
import  ApolloClient, InMemoryCache, HttpLink  from '@apollo/client/core';
import VueApollo from 'vue-apollo'

现在编译器找到了一切。虽然在 Apollo Client 3 文档中我只能找到一个关于新 Client 3 和 Vue 的参考资料，但似乎所有 react 的东西都来自 @apollo/client 而 Vue 和其他来自 @apollo/client/core。
