Transformation error

[shannonmoeller]

Any idea what's causing this?

https://travis-ci.org/douglasduteil/study-node-path-es6/jobs/57027484#L144-L150

I get the same error when running this locally in my project.

babel-node ./node_modules/.bin/isparta cover --report text --report lcov ./node_modules/.bin/_mocha

[douglasduteil]

wow dunno... I will investigate. Thanks

Anything?

[tysoncadenhead]

I'm seeing that issue too on my project. For some reason, the _mocha script has a return inside an if statement. I'm not sure if Mocha intends for that script to be wrapped or something, but the issue is definitely with a return happening directly inside the global context.

[shannonmoeller]

The return is totally valid in a Node context. It's just weird that _mocha is being treated as ES6. Stuff in node_modules usually isn't parsed by babel-node, but in this case we're reaching into node_modules directly so it doesn't know to skip it.

following instructions in the above link and cloning latest mocha solved the problem for me (as of this post, the mochajs team has not published the hotfix to npm yet)

Hi @shannonmoeller @tysoncadenhead @thegoleffect

After some code surfing 🏄
I found out that the problem comes form the istanbul default exclusion pattern that don't match for node_modules/.bin/_mocha
