Hi All, Yesterday I have spent whole day installing Rails 3.0 in a virtual machine and then installing them side by side on a development machine, which runs Linux Mint 8. I already had Ruby 1.8.7 and Ruby 1.9.1p243 installed from packages and Rails 2.3.5 installed from gems. To install Rails 3.0 I have used gem1.9.1, so I have environment almost totally depending on Ruby1.9.1. The problem was having to use Ruby1.9.1 commands as follows: sudo gem1.9.1 install tzinfo builder memcache-client rack rack-test rack-mount erubis mail text-format thor bundler i18n sqlite3-ruby sudo gem1.9.1 install rack-mount—version=0.4.0 sudo gem1.9.1 install rails --pre I also have installed using gem1.9.1 usual database gems that I will need Now I had gem binaries in two directories: /var/lib/gems/1.8/bin/ and /var/lib/gems/1.9.1/bin/ The 1.8 version was already in the $PATH so I could generate applications as usual but to use Rails Beta I had to do following: /var/lib/gems/1.9.1/bin/rails Beta -d mysql same with commands like rake etc. My solution was to create /home/user/bin directory, add it to the $PATH, and put there symbolic links to gems1.9.1 bin directory naming them like rails3, rake3 etc. So far it seems to work I can get welcome pages from both versions displaying correct Ruby version, and other environment data. I am wondering if there’s a better way to set-up described above. Best Regards, Jack
