Script interpreter can't add extra-deps to snapshot

[bitemyapp]

Following does not work:

#!/usr/bin/env stack
-- stack --resolver lts-7.10 --install-ghc runghc --package turtle --package FailureT-15778.1

{-# LANGUAGE OverloadedStrings #-}

import Turtle

main = echo "Hello World!"

FailureT-15778.1 isn't on that Stackage LTS, so this is expected?

[bitemyapp]

That's my point, I specified the version. That's why I said extra-deps in the title.

The issue is actually that the script interpreter was running things with silent verbosity. I've changed it to output error logging, so now the following is outputted:

Error: While constructing the build plan, the following exceptions were encountered:

In the dependencies for FailureT-15778.1:
    mmtl must match -any, but the stack configuration has no specified version (latest applicable is 0.1)

You may also want to try the 'stack solver' command
Plan construction failed.

@mgsloan eggscellent, thank you!
