运行npm Start时，启动脚本丢失错误

当我试图用npm start命令调试我的节点应用程序时，我收到了这个错误。

Error:

检查包装。Json文件有“脚本”属性是否存在。如果不这样更新脚本属性

{
  "name": "csvjson",
  "version": "1.0.0",
  "description": "upload csv to json and insert it into MongoDB for a single colletion",
  "scripts": {
    "start": "node csvjson.js"
  },

其他回答

试试下面这些步骤:

NPM rm -g create-react-app NPM install -g create-react-app create-react-app my-app

这绝对有用!!

如果您正在使用babelify和watchify，请转到:

package.json

并在“脚本”中添加这个:

"scripts": {
    "start": "watchify the-path-to-your-source-jsx-file -v -t [ babelify --presets [ react ] ] -o the-path-to-your-output-js-file"
}

一个例子是:

"scripts": {
    "start": "watchify src/main.jsx -v -t [ babelify --presets [ react ] ] -o public/js/main.js"
}

我只是偶然发现了这个问题。我重新安装了NPM，创建了一个新的React应用程序(所以基本上是一个干净的安装)，仍然没有运气。终于弄明白了:

我的终端机不在正确的位置。

我必须将directory更改到我的应用程序更深一层。所以我的终端在“projects”文件夹里，而不是“my-app”文件夹里

路径:/文件/项目/ app的

请在package.json中的script object中使用下面这行代码

"scripts": {
    "start": "webpack-dev-server --hot"
}

对我来说，它运行得非常好。
