Cannot find module '@date-fns/upgrade/v2'

I got this to work with Yarn by installing it explicitly and then running the command with Yarn. I also needed to install the upgrade package as mentioned as well as a package called "transform-imports". Then I found out that the codemod does not work on files that use decorators.

Hi @danieldunderfelt! Thank you for reporting this one.

It's not clearly stated in README, but @date-fns/upgrade/v2 has to be installed as dependency for your project, the one that you're updating.

1. Install @date-fns/upgrade/v2 as dependency for your project
2. Run codemod

The codemod should not be a dependency in your project.

Regarding not working on files with decorators - that's something I have missed.

I use npm, installed @date-fns/upgrade --save and transform-imports --save but still get the same cannot find module when running the npx codemod

I got it to work by installing this repo locally and running the bin directly
cd node_modules/@date-fns/upgrade-codemod/bin
./date-fns-codemod.js projectdir

After further reconsideration @danieldunderfelt is actually correct :)
I'll merge his PR and publish new lib.
