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/

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"
  ]
}

成功:
