Bug Report

Current Behavior

Module build failed: TypeError: Cannot read property 'auxiliaryCommentBefore' of null

beble-generator/lib/index.js line:47 and line:76

for unknown reason, soametimes Generator arguments:opt can be 'null', so when the code is running in line 76 when we need read some options by using opts.auxiliaryCommentBefore,the exception is happend.Maybe we should add some judgement of the arguments 'opt' with the type 'null'?

Environment

  • babel-generator version(s): [6.26.1]
  • Node/npm version: [8.11.3/5.6.0]

Hey @chlshown! We really appreciate you taking the time to report an issue. The collaborators
on this project attempt to help as many people as possible, but we're a limited number of volunteers,
so it's possible this won't be addressed swiftly.

If you need any help, or just have general Babel or JavaScript questions, we have a vibrant Slack
community
that typically always has someone willing to help. You can sign-up here
for an invite.
