One such error is the “field “browser” doesn’t contain a valid alias configuration”. In this article, we will show you how to fix this error.

Fix #1: Check your import paths

You need to first go to your Webpack configuration and locate the following line:

import DoISuportIt from 'components/DoISuportIt';

Now, you need to change this line to the following:

import DoISuportIt from './components/DoISuportIt';

Now, you need to reload NPM and try again; hopefully, the error will be fixed.

Fix #2: Check the entry value

You also need to check the entry value inside your Webpack configuration to make sure that there is no problem with that.

If you see that a ./ character is missing from your entry value, then make sure to add it and see if the error is fixed.

Fix #3: Check your aliases

Users who had used the same alias already used before faced this issue.

Many users also commented that they used “redux” as an alias, and they faced this issue.

So make sure not to use the same alias you have used before and try again. This will solve the issue.

Fix #4: Check for typos in your configuration

Another possible reason for this issue is if there is a typo in your webpack configuration.

Make sure to fix any typos in the webpack configuration, which should also fix your problem.

If you don’t have an export command at the end of your config file, this error can occur, so make sure to add this line.

export default Config;

Some users also said that using exports instead of export fixed the error for them, so we suggest you try that as well.

Fix #5: Check your Case

The case you are using is also a potential issue so open your file and navigate to this line:

and change it to the following:


Reload the NPM once again, and your error should be fixed now.
