Developer FAQs

How do I fix the error Unchecked dependencies for environment dev?

$ mix -h
Unchecked dependencies for environment dev:
 * nerves (Hex package)
  the dependency is not available, run "mix deps.get"
 * nerves_system_qemu_arm (Hex package)
  the dependency is not available, run "mix deps.get"
** (Mix) Can't continue due to errors on dependencies

If you receive an error similar to the aforementioned when running a mix task, you are missing some required dependencies. Execute mix deps.get to fix this.
