Hi, guys,
I successfully installed the rvm but the rvm command is unavailable ,
the installation message as the following :
dengx@dengx-desktop:~$ gem -v
1.8.5
dengx@dengx-desktop:~$ sudo gem install rvm
Fetching: rvm-1.6.20.gem (100%)
This gem contains only the Ruby libraries for the RVM Ruby API.
In order to install RVM please use one of the methods listed in the
documentation:
https://rvm.beginrescueend.com/rvm/install/
such as,
bash < <(curl -s -B https://rvm.beginrescueend.com/install/rvm)
followed by placing the sourcing line in your ~/.bash_profile or
wherever may
be appropriate for your setup (example, .zshenv, /etc/profile, …):
# Load RVM into a shell session *as a function*
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"
After completing setup please open a new shell to use RVM and be
sure to run
‘rvm notes’ to gain a list of dependencies to install before
installing the
first Ruby. You can read more details about this process on the
above
mentioned install page as well as the basics page:
https://rvm.beginrescueend.com/rvm/basics/
Enjoy!

No, you didn’t . Did you even read the message that you pasted into
your email???
rvm: command not found
No kidding. Try following the directions from the output of the gem
install.

Really? On my system, rails -v shows me something like
22:08 ~ $ rails -v
Rails 3.0.7
or
22:09 ~ $ rails -v
Rails 2.3.11
depending on which Ruby version and (more particularly) gemset I’ve
selected.

That is truth, look my message …

Rails 3 doesn't officially support Ruby 1.9.1 since recent stable

Can you paste the output of “rvm list” here?
You have to make sure that you using correct ruby before you install
anything. Did you make the changes to your profile (~/.bashrc or
~/.bash_profile) as instructed by rvm?

Most likely the case is that it is picking up the rails version
installed on
your system ruby.
Try installing rails again on your rvm ruby
Use ‘gem install rails’, if you use ‘sudo’ then it will install to
system
ruby.

After installing rvm, you should close the current terminal window and
open
a new one. You do not need to install the rvm gem (it is not recommended
either.)
I will assume you are using ubuntu. To install rvm, you need to have
curl
and git installed. (run “sudo apt-get install curl git” if you don’t.)
run in the terminal “bash < <(curl -s
https://rvm.beginrescueend.com/install/rvm)”
After it is complete, you can close that terminal window and open a new
one.
run in the terminal “type rvm | head -1”
if you see “rvm is a function” then everything went well.
https://rvm.beginrescueend.com/rvm/install/
dengx@dengx-desktop:~$ type rvm | head -1
rvm is hashed (/usr/local/bin/rvm)
What is that mean about above ? a hashed function ?

It will make a error if i using the sudo to install it,
something like this as you said ,
dengx@dengx-desktop:~$ rvm use ruby-1.9.2
Using /usr/local/rvm/gems/ruby-1.9.2-p180
dengx@dengx-desktop:~$ gem install rails
ERROR: While executing gem … (Gem::FilePermissionError)
You don’t have write permissions into the /usr/lib/ruby/gems/1.9.1
directory.

BTY, i want to install it again, and i will get a question.
“The file ‘lib’ not found .” , i googled it and saw a post that says add
a
directory “/lib/ruby/gems/ … …”
i did it as that post, but it still not works.

Try this:
rvm use ruby-1.9.2
gem install rails
