How to Uninstall Nuxt modules and packages - vue.js

Question

I'm on Nuxt 2.13 and I wanna remove some packages. previously I would just remove them from the package.json file and would use npm i and the package would be removed but now I get this error:
Module #nuxtjs/google-gtag not found. Please ensure #nuxtjs/google-gtag is in dependencies and installed.

I tried npm uninstall -S -D #nuxtjs/google-gtag and it worked but then when I uninstalled express i got this error again!
how can I safely remove packages from my nuxt app??

Answer 1

your approach is correct, but make sure that the module is not used anywhere.
in the case of Nuxt, besides the package.json, also check the nuxt.config.js (modules && buildModules) and also the plugins folder
