Webpack配置vue打包環境時報錯

Webpack配置vue打包環境時報錯，大片飄紅 頭都大了…

解決方法

• 刪除node_modules文件夾
• 重新配置一下 cnpm install
• 然後再打包然後它好了

看見錯誤的時候一直在想是因爲入口和出口文件不能用嗎，但是不加vue-loader的時候也可以，然後又想是App.vue的錯，代碼重新敲了兩三遍，依然報錯，百度了，最有可能的是node的版本問題，正準備更新的時候，刪除了node_modules 然後重新下載了一下 可以了，啊對 沒有刪除的時候，cnpm install 了但是沒有解決問題。 不知道還有多少坑等着我嗚嗚嗚又是酸菜魚太南了的一天
