@lifeart - The nested try catch seems fine, wanna send a PR?

[lifeart]

 try {
    fs.symlinkSync(canLinkSrc, canLinkDest)
  } catch (e) {
    fs.unlinkSync(canLinkSrc) // error from this point
    return false
  }

win 10, node 10.15, ember-cli 3.7

 try {
    fs.symlinkSync(canLinkSrc, canLinkDest)
  } catch (e) {
    try {
       fs.unlinkSync(canLinkSrc) // error from this point
    } catch (err) {

    }
    return false
  }

works for me
