3. NPM method
Due to the slow installation speed of npm, this tutorial uses Taobao’s mirror and Its command is cnpm. For installation and usage instructions, please refer to: Using Taobao NPM Image.
The npm version needs to be greater than 3.0. If it is lower than this version, you need to upgrade it:
# 查看版本 $ npm -v 2.3.0 #升级 npm cnpm install npm -g # 升级或安装 cnpm npm install cnpm -g
It is recommended to use cnpm installation when building large applications with Vue.js. cnpm can work well with Webpack or Browserify module packager is used with:
# 最新稳定版 $ cnpm install vue@next
Command line tool
Vue.js provides an official command line tool that can be used to quickly build large single-page applications.
# 全局安装 vue-cli $ cnpm install -g @vue/cli # 安装完后查看版本 $ vue --version @vue/cli 4.5.11
Note: vue-cli 3.x and vue-cli 2.x use the same vue command. If you have installed vue-cli 2.x before, it will be replaced by Vue-cli 3.x.
Install @vue/cli-int:
$ cnpm i -g @vue/cli-init
Create project
$ vue init webpack runoob-vue3-test # 这里需要进行一些配置,默认回车即可 ? Project name runoob-vue3-test ? Project description A Vue.js project ? Author runoob <test@runoob.com> ? Vue build standalone ? Install vue-router? Yes ? Use ESLint to lint your code? Yes ? Pick an ESLint preset Standard ? Set up unit tests Yes ? Pick a test runner jest ? Setup e2e tests with Nightwatch? Yes ? Should we run `npm install` for you after the project has been created? (recommended) npm vue-cli · Generated "runoob-vue3-test". # Installing project dependencies ... # ======================== ...
Enter the project, install and run:
