在生产中运行 npm run prod 时出错

Question

当我在 VPS 中运行 npm run prod 时，我一遍又一遍地遇到相同的错误。我的本地开发机器没有问题：

这是错误消息，我的应用程序是带有 Vue 的 Laravel 应用程序，我用它laravel-mix来编译我的资产，我的生产开发人员是带有 Ubuntu 和 LEMP 堆栈的 DigitalOcean VPS：

$ npm run prod

> @ prod /var/www/dtcburger.es
> npm run production


> @ production /var/www/dtcburger.es
> cross-env NODE_ENV=production node_modules/webpack/bin/webpack.js --no-progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js

    throw errnoException(err, 'spawn');

如果您的 Digital Ocean Droplet 只有 1GB 内存，则在运行 npm 生产脚本时可能会遇到内存问题。要解决此问题，您可以尝试将 Droplet 扩大到更大的 Droplet 或使用以下标志运行生产脚本--silent：

npm run production --silent
