  Log:
    Try disabling Travis cache on darwin
    
    to check if it resolves "Permission denied" problem.

    TBH I'm not exactly sure why it happens, but I don't have infinite time
    to understand this. It would be appreciated to identify the root cause
    and remove `DISABLE_CACHE` again if you're sure your patch fixes the problem.
