Problems when adding via 'vue add bootstrap-vue'

[MakiRollDev]

So i tried installing bootstrap-vue via vue/cli and it worked fine until it asked me:
Use babel/polyfill? Yes
after wich it threw TypeError: range.split is not a function i did have some problems before with package.json but i thought i fixed them by renaming package-lock.json (Ithought i might have shut down my pc at the wrong time)

Hi @CuteNickychan. Did you attempt to install on a new project, or an existing one? What options did you choose during the plugin installation?

I'd suggest creating a fresh vue app via the cli and then trying the plugin:

vue create testapp
vue add bootstrap-vue

If you are able to successfully install the boostrap-vue plugin on a new project, I'd suggest using the changes made in the new project as a reference. You can simply add the changes detected by git to your existing project, and boostrap-vue should be usable.
