AWS Elastic Beanstalk无效的二进制软件包 [英] AWS Elastic Beanstalk invalid binary packages

问题描述

我正在将项目从Heroku迁移到AWS.部署后，我一直收到错误消息:无效的ELF标头".使用AWS Lambda时，我发现有类似问题的帖子，但是我不明白为什么我在Elastic Beanstalk中的二进制软件包会遇到问题.

I am working on migrating a project from Heroku to AWS. I keep getting an error after deployment saying: 'invalid ELF header'. I have found posts with similar issues when using AWS Lambda, but I do not understand why I would have an issue with binary packages in Elastic Beanstalk.

Elastic Beanstalk不能提供一个配置好的环境来运行我的类似于Docker的代码吗?我觉得这个问题必须更加复杂，因为在Elastic Beanstalk中找不到其他人遇到这个问题.

Doesn't Elastic Beanstalk provide a configured environment to run my code similar to Docker? I feel like this problem must be more complex as I cannot find anyone else with this issue in Elastic Beanstalk.

这是我得到的确切错误:

Here is the exact error I am getting:

我在Mac上工作，我的代码包含用React，node.js和SQL编写的客户端和服务器代码.我正在通过包含多个文件夹(包括node_modules/)的ZIP文件上传代码.

I am working on a Mac, my code contains both client and server code written in React, node.js, and SQL. I am uploading my code via a ZIP file containing multiple folders, including node_modules/.

推荐答案

某些库对构建它们的操作系统和/或CPU体系结构很敏感.对于以低级语言或链接到系统库的模块实现的情况尤其如此.在这种情况下，您似乎正在使用 bcrypt ，即

Some libraries are sensitive to the operating system and / or CPU architecture on which they are built. This is especially true of modules implemented in low-level languages, or that link to system libraries. In this case, you appear to be using bcrypt which is largely written in C++.

这是您上传到Elastic Beanstalk的zip文件不应包含您的node_modules/文件夹(或Git忽略的其他任何文件)的原因之一.创建要上传到Elastic Beanstalk的zip的最简单方法是

This is one reason that the zip file you upload to Elastic Beanstalk shouldn't include your node_modules/ folder (or anything else that Git is ignoring). The easiest way to create a zip for uploading to Elastic Beanstalk is probably to use git archive:

 git archive -v -o myapp.zip --format=zip HEAD

这将尊重您的无视，而手动压缩将包含它们.

This will respect your ignores, whereas manually zipping will include them.

您的归档文件的根目录中应包含package.json和package-lock.json. Elastic Beanstalk 将从这些文件中安装其自己的node_modules/ (如果存在).这应该确保所有库与其操作系统兼容.

Your archive should include package.json and package-lock.json in its root. Elastic Beanstalk will install its own node_modules/ from these files if they are present. This should ensure that all libraries are compatible with its operating system.
