laravel - Laravel Mix 和 VUE，未找到 VUE

问题描述

所以我一直收到这个 NPM 错误，我无法弄清楚为什么只是 VUE 无法解决。我正在使用 Laravel 5.6。这是 Laravel 的新安装，带有一些轻量级的 webpack 配置。我已将 webpackConfig 中的路径解析为 VUE，我相信它在 webpack.mix.js 中的提取步骤中失败了

Vue 安装在 node_modules/vue

使用 npm run dev 和 npm run prod 生成错误

require('./bootstrap');

window.Vue = require('vue');

/**

解决方案

在您的 webpack.mix 文件中，您有以下行：
path.resolve(__dirname, 'node_modules/vue'),

只要确保这是正确的，可能您需要定位一个 dist 文件夹或类似文件夹，例如

path.resolve(__dirname, 'node_modules/vue/dist'),
