cannot find module vue/ref-transform-CodePudding

I have a freshly created project in vue.js, everything worked(homepage). Then I installed bootstrap-vue with these steps.

$ yarn add bootstrap bootstrap-vue.
$ npm install bootstrap bootstrap-vue --save.

But after installing bootstrap I'm getting stuck with this error: -Error: Cannot find module '@vue/ref-transform'

any tips what can I do please?

this is my package.json

CodePudding user response：

Bootstrap Vue is not compatible with Vue 3.

You need to use Vue 2.
