Webpack build error

[knagyorg]

Hi, I set up empty vuejs webpack project and add vue2-simplert component. But when I build project, I get error:
ERROR in static/js/vendor.9cdb516fd1e83e5588b9.js from UglifyJs
Unexpected token: operator (>) [./node_modules/vue2-simplert/src/main-dist.js:4,0][static/js/vendor.9cdb516fd1e83e5588b9.js:27114,16]

How to reproduce:

vue init webpack my-project
cd my-project
npm install
npm install vue2-simplert --save

use simplert in App.vue

npm run dev   -> app works

npm run build  -> build fails

Can you share version you used ?
I suggest to use latest version.

[knagyorg]

Yes, it's the latest version.
I include my package.json file for clear

Can you upgrade to 0.5.8 ?

[knagyorg]

Yes, now it works
Thanks a lot

[Irfan Maulana]

Have you try this repo : https://github.com/mazipan/vue2-simplert-plugin
It's easier to use in complex project.
All migration process also have been documented there

Thanks for the link - I'll take a look at it.
