How to downgrade the Next js version from ^12.2.2 to 12.2.2?

Question

i am working on next js project and the version used is 12.2.2. mistakenly i upgraded to ^12.2.2 and now i get this warning in my terminal "You have defined experimental feature (outputStandalone) in next.config.js that does not exist in this version of Next.js". How can i work again on the previous version?

Answer 1

If it's just the package version and nothing else changed when you ran an npm upgrade, try:

1. delete the node_modules folder
2. edit package.json to set the version you want (12.2.2)
3. run npm install again

That should remove the old version and the install the specific one you want.
