bootstrap-vue: Cannot read property 'extend' of undefined - v2.0.0-rc.17
When upgrading from 2.0.0-rc.16 to 2.0.0-rc.17 my application fails to start, and gives the following error.
TypeError
Cannot read property 'extend' of undefined
I have confirmed this by creating a brand new site by running the following command, and choosing the bootstrap framework
npx create-nuxt-app example
Application is using nuxt 2.6.1 and bootstrap 4.3.1 Nodejs is 11.9.0 and npm 6.5.0 Test in Firefox 66.0.2 and Chrome 73.0.3683.103 running Windows 10 x64

There’s a fix on the way, please use the thumbs up reaction if you have the same error instead of commenting
v2.0.0-rc.18 has been released.
We’ve also introduced a new option for the Nuxt module that will help reduce bundle size for final prod build, which allows you to choose betwen using the
/esmodules or/srcdirectly (at the expense of taking a few seconds longer for build for tanspilation).Defaults to
/esfor dev build, and/srcfor prod build.Documented in the getting started section.
Thank! Works! 2.0.0-rc.18
We’ve also pinned the issue to the top of the issues page.
I reverted verion rc.15, it worked.
