Troubleshooting Next.js Deployment Failure on Vercel with Emotion Package Missing

I’m experiencing a deployment issue with my Next.js project on Vercel. When I attempt to build and deploy my application, I encounter a module resolution error specifically related to the @emotion/styled package.

Error Details

  • The build process fails with a ModuleNotFoundError
  • The error suggests that the @emotion/styled module cannot be resolved
  • This occurs during the webpack compilation stage

Potential Causes

  • Incomplete package installation
  • Incorrect package dependencies
  • Version compatibility issues

My current setup:

  • Next.js version: 10.0.8
  • Trying to use Material-UI with Emotion styling

Has anyone encountered a similar problem and found a solution? I would appreciate any guidance on resolving this webpack build error.

I went through something similar last month and found a simple fix. First, double-check your package.json and make sure you've explicitly added both `@emotion/react` and `@emotion/styled` as dependencies. Sometimes Vercel can be picky about package resolution.

What worked for me was running a clean install - delete your node_modules folder, clear npm cache with `npm cache clean --force`, then do a fresh `npm install`. This often resolves weird dependency conflicts. Also, consider updating to the latest stable versions of Next.js and Emotion packages to ensure compatibility.

If that doesn't work, try adding a `.npmrc` file in your project root with `auto-install-peers=true` to help Vercel resolve peer dependencies more smoothly. Hope this helps you troubleshoot the deployment issue!

Hey there! I've dealt with similar Emotion and Next.js deployment headaches. From my experience, the issue often stems from how Vercel handles package dependencies. Instead of just reinstalling, try configuring your `next.config.js` to explicitly handle the Emotion setup.

Add a webpack override in your configuration that ensures Emotion's babel plugin is properly recognized. Something like this usually does the trick: set up a custom webpack config that includes the necessary babel plugin for Emotion. This helps Vercel understand how to compile and bundle your styled components correctly.

Also, make sure you're using the latest versions of Next.js and Emotion packages. Compatibility can be tricky, so staying updated is crucial. If all else fails, a minimal reproduction of your project might help pinpoint the exact dependency conflict.

hey, tryd this b4 - u might wanna add babel config in ur next.config.js file. specificly configr emotion webpack plugin. alsp chek ur dependencies r exactly right. vercel can b weird smtimes w/ module resolution

If you're struggling with Emotion package resolution on Vercel, my recommendation is to use the `babel-plugin-emotion` explicitly in your configuration. I've resolved similar issues by adding a custom babel configuration that ensures proper transpilation of styled components.

Try creating a `.babelrc` file in your project root with specific Emotion plugin settings. Add `@emotion/babel-plugin` to your babel presets and make sure it's correctly configured. This approach helps Vercel understand how to process your Emotion styles during the build process.

Additionally, verify your package versions - sometimes mismatched package versions can cause unexpected build failures. A clean install and careful version checking might save you hours of debugging. Good luck resolving your deployment headache!

From a different perspective, I recommend examining your webpack configuration in the `next.config.js` file. Vercel can sometimes struggle with module resolution for Emotion packages, so a custom webpack configuration might be necessary. Try adding a specific webpack override that explicitly handles Emotion's babel plugin and ensures proper transpilation.

In my experience, the key is creating a detailed webpack configuration that tells Vercel exactly how to process your styled components. This might involve adding custom babel settings, specifying module resolution rules, and ensuring all peer dependencies are correctly recognized during the build process.

Additionally, consider using Vercel's build logs and error messages as diagnostic tools. They often provide nuanced insights into exactly where the module resolution breaks down. If possible, try creating a minimal reproduction of your project to help isolate the specific dependency conflict causing the deployment failure.
