大家好 本人是剛學Vue不久的新手

有寫好幾個vue Component，目前想要輸出到npm給其他專案使用
如果只輸出一個的Component index.js 可以成功給其他專案使用
1.但是如果是輸出多個Component的index.js要怎麼寫?
嘗試了好幾天 找不到可以用的寫法

2.其他專案怎麼套用原本Component原有的CSS?

index.js(嘗試過失敗的寫法)

import Env from './views/Env.vue';
import Hello from './views/HelloWorld.vue';

const Components = [
    Env, Hello
]
const install = function (Vue, opts = {}) {
    Components.forEach(component => {
        Vue.component(component.name, component)
    })
}
export default {
    install
}

package.json

{
  "name": "test",
  "private": false,
  "main": "./dist/base.common.js",
  "files": [
    "dist/*",
    "src/*",
    "public/*",
    "*.json",
    "*.js"
  ],
  "scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
    "lint": "vue-cli-service lint",
    "build_lib": "vue-cli-service build --target lib --name base './src/index.js'",
    "build_wc": "vue-cli-service build --target wc  --name base './src/views/*.vue'"
  },
...

請求各位Vue高手幫忙指點迷津 謝謝!!
