[Vuejs]-How to access per project / per preset configuration data in vue-cli 3.x?

So your problem is that you can’t find ~/.vuerc?
I had the same issue and I found the solution here.
The solution is to use the command line

vue config

to see .vuerc, and then use

vue config –delete presets.yourPresetName

to delete your preset.
As well, if you can’t type in your preset name in the terminal because it contains a space or an apostrophe, you can use

vue config –edit

to open .vuerc with a text editor and just edit it there
