While trying to install rvm and ruby on ubuntu, curl is not recognized but is installed

Question

I'm installing rvm/ruby onto ubuntu 12.04 but I'm running into an issue. rvm successfully installs, but afterwards when I try to do `rvm install ruby` I get this output: ``` RVM requires 'curl'. Install 'curl' first and try again. Warning, new version of rvm available '', you are using older version '1.24.7'. You can disable this warning with: echo rvm_autoupdate_flag=0 >> ~/.rvmrc You can enable auto-update with: echo rvm_autoupdate_flag=2 >> ~/.rvmrc /usr/local/rvm/scripts/functions/utility_system: line 21: awk: command not found /usr/local/rvm/scripts/functions/utility_system: line 22: dpkg: command not found /usr/local/rvm/scripts/functions/utility_system: line 191: tr: command not found /usr/local/rvm/scripts/functions/utility: line 210: head: command not found /usr/local/rvm/scripts/functions/utility: line 204: sort: command not found /usr/local/rvm/scripts/functions/utility_system: line 21: awk: command not found /usr/local/rvm/scripts/functions/utility_system: line 22: dpkg: c…

If you'are trying to install RVM system wide, preferred is to use a normal user (not root) for RVM installation.

```
$ curl -L get.rvm.io | bash -s stable
$ source ~/.rvm/scripts/rvm

$ rvm requirements
$ rvm install 2.1.3
$ rvm use --default 2.1.3
```

Also, perhaps off-topic, for a prod server and to replace default 1.8.7 (system wide) you could do it without RVM:

```
$ git clone https://github.com/sstephenson/ruby-build.git
$ cd ruby-build
$ ./install.sh

$ ruby-build 2.1.3 /usr/local
```
