I'm working on a project that depends on react-native-gifted-chat. I want to customize react-native-gifted-chat so I clone it. I do the change. I runnpm i; npm run build. I use watchman to copy the files to my project's node_modules. I run my project, and I get an error about react versions not matching. I understand that react was installed in the react-native-gifted-chat clone. My thing is.. how do I uninstall it? I understand that react is in the devDependencies of react-native-gifted-chat, and I don't need it after doing the build. npm prune --production doesn't remove the devDependencies. How to remove them?

I am not looking for an answer like "Just do npm uninstall react". I am looking to uninstall all devDependencies as I do not need them anymore.

EDIT: OR! Maybe I just don't understand the flow of editing an npm package to my needs?
