This experimental syntax requires enabling one of the following parser plugin(s) with Babel

I’m working on a ember app where I use decorators. I want to use es5-getter-ember-codemod so I did :

jscodeshift -t https://rawgit.com/rondale-sc/es5-getter-ember-codemod/master/es5-getter-em
ber-codemod.js --babel --parser babel ./app/ 
ERR app/models/user.js Transformation error

With --parse babylon I have no errors but nothing is modified.

I tried to add a .babelrc file with :

{
  "plugins": ["transform-decorators-legacy"],
}

But it doesn’t worked.

It works when I use babel ./app.

This can be related to #252

Do you have a clue?

I ended up doing the same as @loopmode above, but got it working by tweaking some different settings in that block.

I eventually just switched to using --parser flow to avoid the problem entirely.

Uh, I didn’t even try --parser flow - if it works, that’s awesome. Will check.
