问题描述

参照官方安装文档安装vue-advanced-chat组件后，即使运行最简单的组件测试用例，也会抛出如下编译错误：

error  in ./node_modules/vue-advanced-chat/dist/vue-advanced-chat.common.js

Module parse failed: Unexpected token (17025:3)
You may need an appropriate loader to handle this file type.

|           ...skinTonedUnicode && { unicode: skinTonedUnicode },
|           ...emojiSummary.name && { name: emojiSummary.name }
|       });

初步判断问题与依赖版本兼容性相关，报错项目的package.json完整配置如下：

报错原因

报错位置的...skinTonedUnicode && { unicode: skinTonedUnicode }属于ES2018标准的对象条件展开语法，当前项目使用webpack3 + babel6的老旧构建栈，存在两个核心问题：

默认配置下babel-loader会直接排除node_modules目录下的所有文件，不会对第三方依赖做语法降级转译
安装的vue-advanced-chat@1.5.5版本打包产物中包含未转译的高版本ES语法，webpack3原生无法识别该语法，直接抛出模块解析失败错误。

解决方案

两种方案二选一即可，优先选择第一种，改动量最小：

方案1：降低组件版本适配现有构建环境
卸载当前安装的高版本组件，安装适配webpack3、Vue2.5.x环境的兼容版本，执行以下命令：
```
npm uninstall vue-advanced-chat
npm install vue-advanced-chat@0.8.6 --save
```
方案2：修改构建配置转译第三方依赖语法
如果必须使用1.5.5版本的组件，可修改构建配置让babel转译该组件代码，补全对应语法转译能力：
1. 打开build目录下的webpack.base.conf.js文件，找到babel-loader的规则配置，修改路径匹配逻辑，将vue-advanced-chat加入babel转译范围，参考配置如下：
```
{
  test: /\.js$/,
  loader: 'babel-loader',
  include: [
    resolve('src'),
    resolve('test'),
    resolve('node_modules/vue-advanced-chat')
  ]
}
```
1. 安装支持对象展开语法转译的babel插件：
```
npm install babel-plugin-transform-object-rest-spread --save-dev
```
1. 打开项目根目录的.babelrc配置文件，在plugins数组中新增刚安装的插件：
```
{
  "presets": [
    ["env", { "modules": false }],
    "stage-2"
  ],
  "plugins": [
    "transform-runtime",
    "transform-vue-jsx",
    "transform-object-rest-spread"
  ]
}
```

注意：所有操作完成后，必须删除node_modules/.cache目录再重启开发服务，否则babel-loader的缓存会导致旧错误持续出现。
