Parser "babylon" deprecated error - webpack build
The problem comes from vue-loader 13.x.x and 14.x.x
Version 15.x.x seems to be fine, but I cannot update my project to 15.x.x without breaking everything. (I guess you'll have the same issue)
I'll log an issue in the project repo and with a bit of lucky they'll release a fix.
EDIT:
For the time being, you can use a forked version of 14.2.2 that I have created to get rid of the message. Not sure if it would be compatible with your build.
Try to replace:
"vue-loader": "13.7.2",
with
"vue-loader": "https://github.com/graux/vue-loader#a0d6b77",
