you need to call rails with a project name: $ rails --help Usage: /opt/local/bin/rails /path/to/your/app [options] Options: -r, --ruby=path Path to the Ruby binary of your choice (otherwise scripts use env, dispatchers current path). Default: /opt/local/bin/ruby -d, --database=name Preconfigure for selected database (options: mysql/oracle/postgresql/sqlite2/sqlite3/frontbase/ ibm\_db). Default: sqlite3 -f, --freeze Freeze Rails in vendor/rails from the gems generating the skeleton Default: false Rails Info: -v, --version Show the Rails version number and quit. -h, --help Show this help message and quit. General Options: -p, --pretend Run but do not make any changes. –force Overwrite files that already exist. -s, --skip Skip files that already exist. -q, --quiet Suppress normal output. -t, --backtrace Debugging: show backtrace on errors. -c, --svn Modify files with subversion. (Note: svn must be in path) -g, --git Modify files with git. (Note: git must be in path) Description: The ‘rails’ command creates a new Rails application with a default directory structure and configuration at the path you specify. Example: rails ~/Code/Ruby/weblog ``` This generates a skeletal Rails installation in ~/Code/Ruby/ ``` weblog. See the README in the newly created application to get going. $ ---
