Why vue.js needs to be mirrored

vue.js needs to be mirrored because the NPM installation method will be slower when building large-scale applications with Vue.js, so you can use Taobao's cnpm mirror to install vue.

Why is vue.js installed using cnpm mirror?

When building large-scale applications with Vue.js, it is recommended to use the NPM installation method. NPM can be used well with module packagers such as Webpack or Browserify. But since npm is foreign, it is relatively slow to use; you can use Taobao's cnpm image to install vue.

First we need to download npm, install node.js, and then install npm. Then, use npm to install the cnpm of the Taobao image.

1. Open cmd and enter the command

npm install -g cnpm —registry=https://registry.npm.taobao.org

Installing Vue requires npm version greater than 3, so we first upgrade npm, enter the command

cnpm install cnpm -g

to install vue, enter the command

cnpm install vue

Install vue-cli and enter the command

cnpm install —global vue-cli

At this time, the environment has been set up.
