It looks like a permissions error, but on what?

Thanks to @jordan0day I have a workaround for this issue. Modify mix.exs for the project like so:

diff --git a/blinky/mix.exs b/blinky/mix.exs
index 346429a..179312f 100644
--- a/blinky/mix.exs
+++ b/blinky/mix.exs

   defp deps do
     [{:nerves, "~> 0.3.0"},

Apparently there's a version mismatch in relx; I'm guessing it's that nerves doesn't like one that's too recent.

I'll be PRing this change soon.

@mobileoverlord - Hopefully you've seen this. I can't wait for your distillery work to get rid of the relx/erlware_commons issues, but what's the ETA on it? Should we merge @CraigCottingham's update in the mean time?

[mobileoverlord]

For backwards compatibility I think we should. The distillery branch is going to be merged soon, but will only work with the latest system_br and therefore the latest systems.

[krisalyssa]

Should I add the same dependencies to the other projects as well?

we should patch :nerves so that it does this and put out a bug fix release. I am going to move this issue over there.

[GregMefford]

@mobileoverlord Is this still an issue now that Distillery support is merged in nerves-project/nerves#59?

[mobileoverlord]

It is not an issue anymore. We should update the examples to pull in the latest versions

[GregMefford]

@CraigCottingham I believe this issue has been resolved by merging in #38.
Thanks again for taking the time to open this PR and please let us know if you still have any concerns! 🚀
