Using RVM in eshell of Emacs

Using RVM in eshell of emacs, I am not able to set the ruby version. Why? Environment : Ubuntu 9.10

/media/Work/rubyworkspace $ ruby -v 
ruby 1.8.7 (2009-06-12开发者_如何学Python patchlevel 174) [i486-linux]
/media/Work/rubyworkspace $ rvm use 1.9.2
Using /usr/local/rvm/gems/ruby-1.9.2-p180
/media/Work/rubyworkspace $ ruby -v
ruby 1.8.7 (2009-06-12 patchlevel 174) [i486-linux]

As far as I can tell, RVM relies on the shell being a "regular" UNIX shell. Selection of the correct interpreter etc. is done using shell variables and these don't apply to eshell which has it's own way of configuring stuff.

One solution is to use M-X term and then use a regular shell inside that. The other is to give rvm.el a shot. I personally have not tried either.

You also can write

[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"

to your .bashrc

good luck
