npm - Don't Want To List Package On devDependencies Inside package.json

Question

When I try to install npm package using command npm i -d <package-name> , it always listing the package inside dependencies instead of devDependencies . It works before, but I suddenly get this problem without knowing what is causing it.

I have tried to reset NODE_ENV (I am not sure if this is related since I use windows), deleting package.lock.json , uninstall VSCode 's extensions, cleaning npm cache reinstall the node_modules and even reinstall NODEJs , but the problem still persist.

Does anyone know the solution?

Answer 1

NPM Docs referring to this

Use -D (mind the uppercase) to save as a devDependency, as -d is the same as --loglevel info
