Vue脚手架部署问题总结

我所遇到的一共两大问题
只有先执行npm install之后才能run serve
否则会报错 vue-cli-serve不是内部或者外部的命令，也不是可运行的程序或者批处理文件的错误

1. 运行npm install会报错

2. 运行npm run serve报错

nodejs官网为 https://nodejs.org/en/

在这里插入图片描述
选择推荐用户最多的使用版本

关于第一次下载nodejs需要注意
最好是按照默认提示一步步按部就班的下载，放到C盘即可

配置环境变量

结果：

项目终端里查看
大家可以使用VScode的CMD终端

一般package.json文件

{"name": "hello-world","version": "0.1.0","private": true,"scripts": {"serve": "vue-cli-service serve","build": "vue-cli-service build","lint": "vue-cli-service lint"},"dependencies": {"core-js": "^3.6.5","vue": "^2.6.11","vue-router": "^3.2.0","vuex": "^3.4.0"},"devDependencies": {"@vue/cli-plugin-babel": "~4.4.0","@vue/cli-plugin-eslint": "~4.4.0","@vue/cli-plugin-router": "~4.4.0","@vue/cli-plugin-vuex": "~4.4.0","@vue/cli-service": "~4.4.0","babel-eslint": "^10.1.0","eslint": "^6.7.2","eslint-plugin-vue": "^6.2.2","less": "^3.0.4","less-loader": "^5.0.0","vue-template-compiler": "^2.6.11"},"eslintConfig": {"root": true,"env": {"node": true},"extends": ["plugin:vue/essential","eslint:recommended"],"parserOptions": {"parser": "babel-eslint"},"rules": {}},"browserslist": ["> 1%","last 2 versions","not dead"]
}

问题一

运行npm install会报错

reason: certificate has expired
：原因：证书失效

解决：

npm config get registry//获得镜像

是以http开头的，淘宝镜像

//清理缓存
npm cache clean --force

//撤销密钥

npm config set strict-ssl false

再次执行

npm install

出现node_modules:结点模块

问题二：

npm run serve

报错：

解决方式（仅限 windows）:

在项目中 package.json 的 scripts 中新增
SET NODE_OPTIONS=–openssl-legacy-provider

{"name": "hello-world","version": "0.1.0","private": true,"scripts": {"serve": "SET NODE_OPTIONS=--openssl-legacy-provider && vue-cli-service serve","build": "SET NODE_OPTIONS=--openssl-legacy-provider && vue-cli-service build","lint": "vue-cli-service lint"},"dependencies": {"core-js": "^3.6.5","vue": "^2.6.11","vue-router": "^3.2.0","vuex": "^3.4.0"},"devDependencies": {"@vue/cli-plugin-babel": "~4.4.0","@vue/cli-plugin-eslint": "~4.4.0","@vue/cli-plugin-router": "~4.4.0","@vue/cli-plugin-vuex": "~4.4.0","@vue/cli-service": "~4.4.0","babel-eslint": "^10.1.0","eslint": "^6.7.2","eslint-plugin-vue": "^6.2.2","less": "^3.0.4","less-loader": "^5.0.0","vue-template-compiler": "^2.6.11"},"eslintConfig": {"root": true,"env": {"node": true},"extends": ["plugin:vue/essential","eslint:recommended"],"parserOptions": {"parser": "babel-eslint"},"rules": {}},"browserslist": ["> 1%","last 2 versions","not dead"]
}
