Julia: ERROR: LoadError: Failed to precompile a module after loading another one

I was using Gadfly in Julia, then I added the packages StatsModels and GLM and got this error at the line using Gadfly:

INFO: Precompiling module Gadfly.
ERROR: LoadError: LoadError:

The whole message has 400 lines and the stacktrace is 200 levels deep, so I pasted the most relevant bits for brevity. I restarted Julia, removed StatsModels and GLM with Pkg.rm(), then also removed and added Gadfly, and got exactly the same error. How can I fix it?

After hours of searching and trying, I talked to a Julia expert. This looks like a compiler error. Although it's undesirable to reset all Julia packages, the only solution was to move ~/.julia to a backup:

mv ~/.julia ~/.julia_backup

Then restart Julia and run

Pkg.add.(["Gadfly", "StatsModels", "GLM"])
using Gadfly, StatsModels, GLM
