问题
I am in the process of installing Ruby on Rails on windows 7. I installed ruby-1.9.2 (in c:\ruby) and I've installed rails using the gem install rails command (doing this from c:\ruby\bin since this is the only place i can call the command). I've then run rails new my_app command.
The problem that I have is trying to run the rails server command from inside the apps folder (c:\ruby\bin\my_app) I get the message: 'rails' is not recognized....
What have I done wrong?
回答1:
On Windows you need to set your system PATH variable (My Computer -> Properties -> Advanced -> Environment Variables -> System variables)
Append the PATH Variable value:: c:\ruby\bin;

I'm a windows 7 user, and I was able to get rails working by following this guide: http://www.wiki.devchix.com/index.php?title=Windows_-_Rails_3 I know linking is frowned upon, but the windows 7 installations is quite detailed, and the devchix guide is excellent. I store my apps on the desktop in a folder called 'rails' not in the ruby bin.
