I am adding new post to my blog almost after a year and half. It's not that I was not involved in any technical work or not learned any thing during this time, but for some strange reason I could not continue writing.
Anyway, here I am trying to learn Ruby on Rails (RoR) because it's been a long time since I've involved in real programming work. For the last few weeks I've been going through articles, tutorials, etc. on Ruby (and Rails) and learned a lot about its architecture. One thing I consistently doing while going through those materials is that when it came to installation and other configuration part, I used to skip the entire chapter. I wasn't realizing what I am missing until recently I tried to install Rails framework on my Linux Mint instance.
I got the ruby installed from Software Manager and rails using the command
$ sudo gem install rails
When rails is installed, I suddenly fired a command to create new website
$ rails new my_first_site -d mysql
Rails threw few strange error messages saying that it can't install mysql gem. Thinking that installing a MySQL server and client tool will help, I fired sudo apt-get install command to get them installed. I got disappointed when I still see those strange messages again. Realizing that it's time to get help from Google and I found the solution in no time. I actually needed MySQL library for Ruby. So, here it goes with the following command;
$ sudo apt-get install libmysql-ruby libmysqlclient-dev
Now it's time to install mysql gem.
$ sudo gem install mysql2
Rails created the new site properly and when I tried to run the server, it again threw strange error message. Don't know why but I always find messages in Linux very strange and cryptic. The message was about missing JavaScript engine ( though I find messages cryptic, I always read them correctly). Now, installing Node.js is simple;
$ sudo apt-get install nodejs
Phew!
Finally, I got the Ruby on Rails framework ready and I am all set for my practice session.
Update: Linux Mint doesn't have MySQL server and client pre-installed. The following command does the trick;
$ sudo apt-get install mysql-server
