API Error: Error: connect ECONNREFUSED 127.0.0.1:389 Apollo-React MongoDB

Question

我正在尝试在 Windows 环境中运行使用 Apollo(GraphQL)、React、Webpack 和 MongoDB 的 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
node 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
mongodbv^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…

Answer 1

可能这个地址正在使用：127.0.0.1:389，更改端口。

Answer 2

确保 MongoDB 服务器在 windows 环境中启动，方法是使用管理员权限打开 cmd 并通过写入

启动 MongoDb 服务器

net start MongoDB

API Error: Error: connect ECONNREFUSED 127.0.0.1:389 Apollo-React MongoDB

API Error: Error: connect ECONNREFUSED 127.0.0.1:389 Apollo-React MongoDB
