Creation of vue scaffolding

1. Set the default warehouse of npm to the domestic Taobao mirror, 2 methods:

  ① Method 1:

npm config set registry https://registry.npm.taobao.org

  After execution, confirm whether the setting is successful: npm config get registry

  If you see the return to Taobao mirror image, it means success!

  ② Method 2: Alternatives

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

  Confirm whether the installation is successful: cnpm -v

  Seeing the version number indicates success!

2. Use npm or cnpm to install a command-line tool that repeatedly generates scaffolding projects:

//用 npm 安装：
npm i -g @vue/cli 
// 如果说 FEXIST 错误，也可以换成 
npm i -g @vue/cil  --force
//如果 npm 出错，可换成：
cnpm i -g @vue/cli

3. Verify that vue/cli is installed successfully: vue-V

    Seeing the version number indicates that the installation was successful!

4. Emphasis: on a computer, no matter how many projects will be done in the future, vue/cli only needs to be installed once when it is used for the first time!

5. Create a vue project:

    ①Find the folder location of the project to be created, vue create custom project name;

    ② Enter vue ui on the command line to create a Vue project visually;
