Mix igniter.install hangs

Hi all,

I am creating a package and wanted to add igniter for the basic setup.
It isn’t yet published, but is at Faulty.

I tried using the igniter installer with the mix igniter.new test_app --install faulty@github:Hermanverschooten/faulty and that worked nicely.
I then made some changes and ran mix igniter.install faulty@path:../faulty to use my local dev version and that too works. Nice!

Now I wanted to test it against one of my real apps, I added {:igniter, "~> 0.4"} to mix.exs and ran mix deps.get and mix compile.

But when I run mix igniter.install faulty@path:../faulty, I get a list of applications analyzed and then it just hangs. When I run it with MIX_DEBUG=1 I get this at the end

==> admin
-> Running mix will_recompile (inside Admin.MixProject)
<- Ran mix will_recompile in 0ms
<- Ran mix deps.compile in 4181ms
-> Running mix igniter.install faulty@github:Hermanverschooten/faulty (inside Admin.MixProject)
-> Running mix compile --no-compile (inside Admin.MixProject)
-> Running mix loadpaths --no-deps-loading --no-compile (inside Admin.MixProject)
<- Ran mix loadpaths in 0ms
-> Running mix compile.all --no-compile (inside Admin.MixProject)
<- Ran mix compile.all in 5ms
<- Ran mix compile in 8ms

and then it hangs.
I have tried cleaning, even removing the whole _build folder.
Every time, it just hangs, and I don’t know why.
