I’m currently working on a project that requires me to takeover an existing Ruby on Rails website and to finish it. I’m very new to this, and have some problems.<\/p>\n
I can’t even start the server from the terminal, I suspect it is a version related problem, since I’ve just configured my computer to work with Ruby on Rails, and the website development begun a year or two ago. If I create and work on a project myself, everything works fine. I’m on MacBook under OSX Mavericks.<\/p>\n
Here are some specifics:<\/p>\n
To start the server I go into the project directory with my terminal and type:<\/p>\n
rails server\n<\/code><\/pre>\nThis command gives me the following error message:<\/p>\n
