So, the error is pretty clear - you are trying to open '/cache/parks_extended_info.csv', and that fails with permission denied (errno 13). It's not clear what mode you are opening it with - for reading or for writing? Some wild speculation - are you really intending to open '/cache/parks_extended_info.csv' or should that path be prepended with your project path? When you run it in development, your working directory is probably '/path/to/project', and so when you open 'cache/parks_extended_info.csv', it correctly opens '/path/to/project/cache/parks_extended_info.csv'. When you run it in production, working directory is probably '/', so when you open 'cache/parks_extended_info.csv', it tries to open '/cache/parks_extended_info.csv', which probably doesn't exist. On the other hand, if you are really trying to open '/cache/parks_extended_info.csv', then you just need to make sure that you have appropriate read permissions on the file, and execute permissions on any intermediary directories, for the user that your code is running as. If you run these commands, it should be clear why you are denied: ls -ld /cache ls -l /cache/parks_extended_info.csv If you intend to write to the file - or open the file in write or append mode - you must also have write permission to the directory, and to the file if it already exists.
