问题现象

需要从github.com下载，在生产环境（有npm镜像，但无法直接连外网）情况下无法使用

解决方案：去掉使用Squire的MarkDown编辑器tui-editor

准备：全局安装sass
1、下载sass包
这里以4.12.0版本为例
npm install时会提示地址，4.12.0版本在64位linux下链接地址如下所示：
https://github.com/sass/node-sass/releases/download/v4.12.0/linux-x64-64_binding.node
上传到服务器的/tmp目录
2、全局安装
export SASS_BINARY_PATH=/tmp/linux-x64-64_binding.node
npm cache clear --force
npm install -g node-sass@4.12.0

在vue-element-admin模板中去掉tui-editor
1、修改package.json
删除包括tui-editor的1行

2、删除tui-editor相关文件

rm src/components/MarkdownEditor/index.vue
rm src/views/components-demo/markdown.vue

vi src/router/modules/components.js   删除@/views/components-demo/markdown相关内容，如下所示：
    {
      path: 'markdown',
      component: () => import('@/views/components-demo/markdown'),
      name: 'MarkdownDemo',
      meta: { title: 'Markdown' }
    },

3、安装saas包
npm cache clear --force
rm -rf package-lock.json
npm install --unsafe-perm

4、运行和打包
npm run dev 
npm run build:prod
