How many rake tasks can be run at once in rails?

How can I install the MySQL gem on Ruby 1.8.7 using RVM?

  • I tried to run " gem install mysql " to install the mysql adapter for ruby 1.8.7, but I get this error rake/rdoctask is deprecated.  Use rdoc/task instead (in RDoc 2.4.2+) !!! The bundled mysql.rb driver has been removed from Rails 2.2. Please install the mysql gem and try again: gem install mysql. rake aborted! no such file to load -- mysql note: I'm using rvm

  • Answer:

    The problem was that I didn't install the mysql-dev lib. Install it, then it will works fine.
