我的项目最近开始抱怨当我运行 npm run dev 脚本时它无法解析反应，即：cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules -- config=node_modules/laravel-mix/setup/webpack.config.js

好像 npm 找不到 node_modules 目录？

它在我的 Windows 机器上运行良好，但是当我将它上传到 Ubuntu 服务器时出现错误。我尝试了各种方法，比如删除 node_modules 和锁定文件，清理 npm 缓存，检查 $NODE_PATH，重新安装 nodejs 和 npm 无济于事。我不知道这是路径问题，还是我在服务器上遗漏了一些东西或什么。

我会很感激你有任何提示。

我的 package.json：

    "private": true,
    "name": "Write.nogetdigitalt.dk",
    "version": "0.0.1",
    "scripts": {

webpack.mix.js

const mix = require('laravel-mix');
const webpack = require('webpack');

mix.webpackConfig({
    resolve: {
        extensions: ['.js', 'jsx'],
        alias: {
            'react': 'React'
        }
    },
    plugins: [
        new webpack.ProvidePlugin({
            'React': 'react',
            $: 'jquery',
            jQuery: 'jquery',
            'window.jQuery': 'jquery',
            Popper: ['popper.js', 'default']
        })
    ]
})
.disableNotifications()

.react('resources/js/app.js', 'public/js')
    .sourceMaps()
.sass('resources/sass/app.scss', 'public/css');

错误信息：

您没有安装软件包依赖项。

npm install

执行后，节点模块目录已创建。并启动您的应用程序。

npm run developement

对于遇到此类问题的其他任何人，最好path从 NodeJS使用不同操作系统之间的路径定义

`const path = require('path');
[...]
resolve: {
        extensions: ['.js', 'jsx'],
        alias: {
            'react': path.resolve(__dirname, 'Path to your folder to alias')
        }
    }`
