babel 5.8.23 use script no error

but babel 6.1.19 use script error Uncaught TypeError: Cannot read property 'keys' of undefined

why error 6.1.19 yet upgrade

Answer 1

The babel-browser package has now been removed and new versions of it won't be released. There's no use case for it in Babel 6.

check this babel 6
