function Skylight.Plug.init/1 is undefined

[fbjork]

Getting this error when I try to boot my Phoenix 1.3 app. Any ideas?

@fbjork sorry for the delay in replying to this. I will try to investigate soon and get back to you.

Did you run:

mix deps.get
mix skylight.fetch

[fbjork]

I ran mix deps.get before. I get the same error after trying mix skylight.fetch

[wagenet]

Sorry about this. I will try to allocate some time to give it a more in-depth look soon. Once we get it sorted out, I'd be happy to reset your trial period (assuming you are on a trial right now).

I also can't compile after running mix skylight.fetch, the error is: "Run mix skylight.fetch"

I had this same issue. In looking at the compile message it was only compiling one file. I looked into it a bit more and found out a few things. The skylight package mix.exs file has a elixirc_paths call that checks SkylightBootstrap.artifacts_already_exist? Depending on that call it can compile additional files needed to boot the server. Looking into that further I found that the default path they are looking for the artifacts in the compile step are under /deps/skylight/tmp

If you run mix skylight.fetch from your root project folder the artifacts are placed under /tmp As you can see there is a directory mismatch.

I was able to get around this by:

cd deps/skylight
mix deps.get
mix skylight.fetch
cd ../..
mix deps.compile skylight
mix phoenix.server

@Dreamer009 if you're up for it, a PR to fix this would be awesome

@wagenet @Dreamer009 any update on this issue? Would love to start using this library in production to monitor our Elixir apps.

@fbjork right now we don't have any Elixir devs on our team. We'd still love to get this working, but haven't had any spare time to attempt to figure this out.
