导入关键包

 npm install @antv/x6 --save

npm install @antv/x6-vue-shape 

保存插件 (可选)

npm install --save @antv/x6-plugin-clipboard @antv/x6-plugin-history @antv/x6-plugin-keyboard @antv/x6-plugin-selection @antv/x6-plugin-snapline @antv/x6-plugin-stencil @antv/x6-plugin-transform insert-css

写好的组件直接导入即可
