我的项目
大家好
此错误显示。。接下来我要做什么？？？您应该在package.json中将react脚本作为devdependences
{

"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"start": "react-scripts start",
"build": "react-scripts build"

},
"devDependencies": {
"react-scripts": "^1.1.1"
}
}
npm install --save-dev react-scripts
应该更好启动简单项目的最佳方式 首先安装nodejs（您需要一台服务器在本地运行您的应用程序） 打开命令提示符 1:npm安装-g创建反应应用程序 2：创建react应用程序您的应用程序名称 转到目录路径（例如：cd您的应用程序名称） 最后：npm开始
就是这样尝试npm安装--保存开发反应脚本这里是添加在下面的
index.html
