Install node, vue and other environment configurations in MAC environment

Web development generally involves some environment configuration. The last two articles I wrote were about the configuration of the back-end environment. Next, I would like to introduce the configuration of the front-end environment. Hope it can help Xiaobai.

1. Node installation configuration

1. Download the installation version of node: https://nodejs.org/en/download/ Just "Next".

After the installation is completed, the page prompts:

This package has installed:

• Node.js v14.17.4 to /usr/local/bin/node

• npm v6.14.14 to /usr/local/bin/npm

Make sure that /usr/local/bin is in your $PATH.

1) After the installation is complete, use the command to test and check the node version: node - v

2) Since the new version of node will be installed together with npm, there is no need to install npm deliberately

Test whether npm is installed and check the version npm -v

3) If the installed version is an old version, you can use the npm command to upgrade:

$sudo npm install npm -g

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

（1)$sudo npm install    
（2) $sudo npm run dev  #注意每次都要运行这行命令

2. Vue installation configuration

 $sudo npm install -g vue-cli

not command found Just wait for the words [After the installation is successful, you can use the vue -V command to check whether the installation is successful. If the installation is successful, the version number of the currently installed scaffolding will be displayed]
