npm build issues stemming from browserlist configurations

I am encountering an issue with my create-react-app failing to build, showing the following error:

./src/index.css
Module build failed: BrowserslistError: Unknown browser query `dead`
    at Array.forEach (<anonymous>)

I have carefully reviewed my package-lock.json file and updated all packages that rely on browserslist. However, some of these packages do not upgrade to version 3 or above, which I suspect may be causing the problem. The packages in question are:

-autoprefixer -babel-preset-env -babel-preset-react-app -postcss-merge-rules

I am contemplating removing these packages, but other dependencies in my project rely on them as well. As a result, I feel a bit stuck and uncertain about what steps to take next. While the application runs without issues, it fails to build properly, making me unsure if it would function correctly on a development server.

Below is a snippet from my package.json file:

   {
  "name": "dashboard",
  "version": "0.1.0",
  "private": true,
  // Rest of the content remains the same

Answer №1

After reviewing your package-lock file and updating the versions, did you remember to execute npm install again?

Another option is to run npm update to see if that helps resolve the issue.

If the problem persists, you can use npm ls to display all packages and their dependencies. Look for the package with a dependency on an old version of BrowserList. Check if you can update that package, otherwise consider reaching out to the package owner for assistance.
