Question

我是React-Native的新手，我想安装yarn 以下命令是我初始化yarn start后收到的错误我还提供了我安装的npm和nodejs的版本

PS E:\Native\confusion> node -v    
v12.18.1
PS E:\Native\confusion> npm -v
6.14.5
PS E:\Native\confusion> yarn -v     
1.22.4
PS E:\Native\confusion> yarn start                                                               
yarn run v1.22.4
error Command "start" not found.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.

这是我的package.json文件

{
  "name": "confusion",
  "version": "0.1.0",
  "private": true,
  "devDependencies": {
    "react-native-scripts": "2.0.1"
  }
}

Answer 1

问题是，在package.json中没有为start命令定义任何内容。为了对其进行修复，您必须像这样创建一个新的json-node，并用您希望启动脚本执行的任何命令填充它：

{
  "name": "confusion",
  "version": "0.1.0",
  "private": true,
  "scripts": {
    "start": "COMMAND WHICH SHOULD GET EXECUTED GOES HERE"
  }
  "devDependencies": {
    "react-native-scripts": "2.0.1"
  }
}

定义此命令后，可以执行yarn start，它将运行您的命令。
