Uncaught TypeError: Cannot read property 'setEncoding' of undefined

[dniku]

Steps to reproduce: no idea. I had a somewhat broken compilation cache (see atom-haskell-archive/haskell-ghc-mod#212) and I was issuing commands like stack clean. After I switched back to the Atom window, I had this error.

Uh. My response would be pretty much the same as in atom-haskell-archive/haskell-ghc-mod#211... Frankly, I would suspect faulty RAM, but that's baseless conjecture of course. Also might be a bug in Atom, but don't quote me on that.

I will point out that the error is thrown from the depths of Atom internals, so not much I could possibly do, even if I knew what.

Just installed ide-haskell-hasktags, and having the same. Can the missing hasktags be the cause?

[lierdakil]

@cblp, generally, you would expect something like this from missing hasktags:

Since the code base changed a lot since this was last reported, I would appreciate it if you'd provide a complete report. There's a clipboard icon on the big scary error message that should copy the Markdown-formatted report into the clipboard:

[Enter steps to reproduce:]

1. Edit stack.yaml
2. Very big extra-dep library takes too long to build

@cblp, thanks.

It looks like process dies before Atom sets up event handlers... Which I honestly have no explanation for.

So... I've released v0.0.14, which uses node's child_process directly without Atom's wrappers. Let's see if that helps.
