Hi @Arpita

There is a webpack version conflict where one version is found, while a different version is required as a dependency of another package.

The fix is provided:

Either upgrade/downgrade the dependencies you are using in order to satisfy all packages, otherwise you can use NPM_FLAGS environment variable to pass either --force or --legacy-peer-deps to work around the dependency issue.

I’m sorry , but couldn’t understand your response because I just started to use that.
so could you please describe this bit more.
Thank you :blush:

Hi @Arpita,

You need to follow this to declare a variable:

The variable name would be NPM_FLAGS and value would be --force or --legacy-peer-deps.
