在Ubuntu上安装graphql-yoga时引发的错误

Question

Errors after installing GraphQL Yoga

我试图按照Edureka https://www.youtube.com/watch?v=rpJO0T08Bnc的教程视频学习，并使用其他说明在Ubuntu上进行安装。发生了严重错误，因为我无法在localhost：4000上访问该应用程序。 任何帮助将不胜感激。

Answer 1

您创建服务器了吗？让我跟随。

1. yarn add graphql-yoga或npm install graphql-yoga --save
2. 创建'.babelrc'，然后写入{ "presets": [ "env", "stage-3" ] }
3. 纱线添加全局babel-cli，纱线添加babel-cli babel-preset-env babel-state-3 如果您想使用es6，请安装这些。您可以安装它。

4. create the index.js并添加

   `import { GraphQLServer } from 'graphql-yoga';
    import resolvers from './graphql/resolvers'
   
     const server = new GraphQLServer({
         typeDefs: "./graphql/schema.graphql",
         resolvers: resolvers
   }); 
   
   server.start(() => console.log("Graphql Server Running "));`
   

5. 这是我的package.json。遵循此“脚本”

   { "version": "1.0.0", "main": "index.js", "license": "MIT", "dependencies": { "graphql-yoga": "^1.16.7" }, "scripts": { "start": "nodemon --exec babel-node index.js" }, "devDependencies": { "babel-cli": "^6.26.0", "babel-preset-env": "^1.7.0", "babel-preset-stage-3": "^6.24.1" } }

6. 制作schema.graphql，resolvers.js
