当我在控制台中键入$npm build时，bash脚本并没有运行

Question

我想写一个批处理脚本(build.sh(来安装依赖项，同时运行前端和后端

package.json文件

"scripts": {
"dev": "nodemon server.js",
"client": "cd client && npm start",
"start": "concurrently "npm run dev" "npm run client" ",
"build": "chmod +x ./build.sh"
},

build.sh文件

#!/bin/bash
npm run build
npm i aws-sdk body-parser concurrently cors dotenv express joi mongoose multer multer-s3 
cd client
npm i axios bootstrap config jquery node-modules react react-bootstrap react-dom react-scripts redux redux-form redux-thunk web-vitals 
cd ..
npm start

我不确定我错过了什么才能让它正常运行？提前感谢！

当我在命令行(当然是在应用程序的目录中(中键入$ npm build时，我得到的是：

Answer 1

build不是npm的有效CLI命令。要运行在package.json中定义的build脚本，请执行$ npm run build。

Answer 2

"build": "chmod +x ./build.sh"

应该是：

"build": "./build.sh"

chmod +x只是使build.sh文件可执行，它实际上并没有运行它

然后，要从npm运行build命令，您必须像另一个答案所说的那样使用npm run build。
