Elastic Beanstalk上传和部署错误：错误：找不到模块“ semver”

Question

This is my first time uploading a Node.js/Express app to Elastic Beanstalk/AWS. The server folder uploaded fine. But on another environment, my client folder failed to load.

module.js:478
throw err;
^

Error: Cannot find module 'semver'
    at Function.Module._resolveFilename (module.js:476:15)
    at Function.Module._load (module.js:424:25)

    at Module.load (module.js:494:32)
    at tryModuleLoad (module.js:453:12)
    at Function.Module._load (module.js:445:3)

I don't understand this error or the cause. Can anyone help?

It prompts to reinstall/upgrade node, but I don't believe I can do so on AWS ...

Answer 1

The problem was my own lack of knowledge about Node deployments. I was trying to upload my entire client folder.

What I should have done is run npm run build to create a dist file (using a long webpack script) and uploaded that to AWS. In that case, none of these dependencies are required as the files are served statically.
