我是 Vue 的新手，我對一個插件有疑問。我正在嘗試加載 vue-sanitize（此處：https ://www.npmjs.com/package/vue-sanitize ），但出現以下錯誤：您可能需要適當的加載程式來處理此檔案型別。
main.js 中的匯入
import Vue from 'vue'
import VueSanitize from "vue-sanitize";
Vue.use(VueSanitize);

我不知道怎么了。
其他資訊：
- 節點版本 v16.15.0
親切的問候
uj5u.com熱心網友回復：
解決了：
- 將 babel-core 更新到 v6.26.3
- 將 babel-preset-env 更新到 v1.7.0
- 將 babel-plugin-transform-object-rest-spread 添加到開發依賴項
- 插件添加到 .babelrc 檔案：
{
"presets": [
["env", {
"modules": false,
"targets": {
"browsers": ["> 1%", "last 2 versions", "not ie <= 8"]
}
}],
"stage-2"
],
"plugins": ["transform-vue-jsx", "transform-runtime", "transform-object-rest-spread"]
}
- 更新了 webpack 基本配置：
{
test: /\.js$/,
loader: 'babel-loader',
include: [
resolve('src'),
resolve('test'),
resolve('node_modules/webpack-dev-server/client'),
resolve('node_modules/sanitize-html/node_modules')
]
},
但仍然出現錯誤：
未捕獲的 ReferenceError：未定義匯出 webpack:///node_modules/sanitize-html/node_modules/htmlparser2/lib/index.js?2133
編輯：將 .babelrc 中的配置更改為
"modules": "commonjs"
