【中文标题】使用 ZIP 将 nodejs 应用程序部署到 Elastic BeanStalk => 找不到本地包

【英文标题】：nodejs app deployment with ZIP to Elastic BeanStalk => can't find local package

【发布时间】：2020-09-02 02:02:01

【问题描述】：

在 Elastic Beanstalk 上，我想使用 zip 功能而不是使用命令 eb deploy 的 EB CLI 上传我的应用程序

不幸的是，我收到以下错误，服务器在子目录./src/server/ 中找不到本地模块。

提前感谢您的建议

我做了什么实验

用我的代码测试eb deploy=>成功 压缩我的代码并将其加载到 Elastic Beanstalk => 失败 比较从第 1 步和第 2 步创建的 zip => 找不到任何差异

代码在我的本地机器上始终运行良好！

module.exports=

【参考方案1】：

无需深入研究问题，试试这个 zip app.zip -r * .[^.]* -x *.git* *.env*

我也遇到了同样的问题，但是成功了
