使用 element-plus

之所以 element-plus 展示错误是因为 css 没加载完，可以用如下方式加载，完整 demo 在我写的插件模板 https://github.com/1226085293/cc-plugin-template

interface css_info {
  /** css 路径 */
  url_s: string
  /** 挂载节点 */
  parent: ParentNode
}

const option: vue.Component = {
  template: fs.readFileSync(`${__dirname}/container.html`, 'utf-8'),
  methods: {
    /** 动态加载 css */
    load_css(info_as_: css_info[]): void {
      info_as_.forEach((v) => {
        let css = document.createElement('link')
        css.rel = 'stylesheet'
        css.href = v.url_s
        v.parent.appendChild.call(v.parent, css)
      })
    },
  },
  data() {
    return {}
  },
  watch: {},
  created() {},
  mounted() {
    this.load_css([
      {
        parent: document.head,
        url_s: config.path_s + '/node_modules/element-plus/dist/index.css',
      },
      {
        parent: this.$el,
        url_s: config.path_s + '/node_modules/element-plus/dist/index.css',
      },
    ])
  },
}
