mongodb - API 错误 : Error: connect ECONNREFUSED 127. 0.0.1:389 Apollo-React MongoDB

Question

我正在尝试在 Windows 环境中使用 Apollo(GraphQL)、React、Webpack 和 MongoDB 运行 API 服务。服务启动成功，但是当我发送第一个请求时服务崩溃了。

我正在使用这个版本:

• npm v5.6.0
• 节点 v8.9.4
• webpack v3.8.1
• webpack-dev-server v3.0.0
• apollo-server v^0.3.3
• apollo-upload-server v^4.0.0-alpha.3
• mongodb v^2.2.33

这是服务启动时的输出:

C:\test-dev3\name_app\api>npm run start

Webpack is watching the files…

可能这个地址正在使用:127.0.0.1:389，换个端口
