@D-zilch this can happen if you have nothing for "dependencies" key in package.json. try making it blank: "dependencies": {}

Face the same issue when trying to run in lerna monorepo

This means it can not find the package in the package-lock.json file. In my case, I was using: npx patch-package History where I should have been using: npx patch-package history Yes, it is case sensitive. The error message could do with improving.

[StephenHeise]

I have a patch to improve the error message. No idea how to create a PR for it - currently I get a permission denied when I try to push my local branch. I'm a GitHub newbie and can't find anything about how contribute to this project. Any help?

In my case, I had both package-lock.json and yarn.lock files. It turns out the package-lock.json has not been updated as I have been using yarn. I had to delete package-lock.json file.
