Re: How to completely reinstall my rails environment on Mac Lion?

[Rocky]

$gem uninstall rails -a

... will un-install all versions of rails.

$gem install rails

... puts it back again.

You can check your rails version before and after by doing:

$rails -v

Hi,

I was learning rails and have completed some projects. On my laptop everything worked for quite some time. However now when I run rails new testapp, for example it doesn't generate even the first testapp. How can I completely reinstall a rails environment on my mac? I ran several step by step tutorials how to do this, but it seems that the old rails environment is conflicting. I also downloaded Xcode already, tried rvm, tried Homebrew everything seems. It just doesnt work.

Help. I want to continue developing.

I would also recommend using rvm - ruby version manager. It allows you to easily install and switch between versions of ruby and maintain multiple sets of gems...to include rails.

[hanish jadala]

gem list | cut -d" " -f1 | xargs sudo gem uninstall -aIx

 THIS COMMAND WILL UNINSTALL ALL THE GEMS IN UR SYSTEM .AFTER THAT INSTALL AGAIN WHAT YOU NEED.
