Every vue component returning Cannot read property 'parseComponent' of undefined

I had exacly the same problem and just figured it out, I hope this helps someone. First I changed the vue template compiler to:

"vue-template-compiler": "2.6.11"

and the I also had to change the vue version to the latest realese, in my case:

"vue": "2.6.11"

Try running this command

npm update vue-template-compiler
