I installed RVM with a few versions of Ruby-interpreters some time ago.
How I can to update it, because new versions are already released?
I found only one way:
rvm install 1.9.2-rc1 && rvm remove 1.9.2-preview1, but my gems are lost.
Can I update branches time to time? I haven’t found any tips in the documentation.
Current rvm version provides an easier way to do this. The ‘upgrade’ option will migrate gem sets, wrappers and environment files –
$ rvm upgrade 1.9.2-p136 1.9.2-p180
To find out if there is a more recent stable version of a ruby implementation for you to upgrade to, first get the latest version of RVM and then enumerate the known versions of Ruby.
$ rvm get stable $ rvm list known
You can compare this the ruby versions installed on your system
$ rvm list rubies
rvm upgrade 1.9.2-preview1 1.9.2-rc1 command or watch this screencast
AFAIK, there is no automatic way to do this at the moment, but something like this enables you to keep your gems:
rvm use 1.9.2-preview1 rvm gemset export rvm install 1.9.2-rc1 rvm use 1.9.2-rc1 rvm gemset import rvm remove 1.9.2-preview1
Now, for automating updates, you would have to detect version changes, that is easy, as you can simply use the return value of
rvm use 1.9.2. Finding out what the new version is (
1.9.2-rc1) is unnecessary, as it is aliased as 1.9.2. The trick is to find the latest installed version of 1.9.2. You could do something like this in a cron job:
# make sure you source rvm first rvm update --head rvm reload if [ ! rvm use 1.9.2 ]; then for ruby_version in `rvm list strings`; do # find the latest version of 1.9.2 case $ruby_version in ruby-1.9.2-*) latest192=$ruby_version;; esac done rvm use $latest192 rvm gemset export 192.gems rvm install 1.9.2 rvm use 1.9.2 rvm gemset import 192 rvm remove $latest192 fi
Did not try that, but I have similar code in my update script. I also slipped in a
gem update and other stuff.
Feel free to visit the #rvm IRC channel on Freenode.
you can install latest rvm and ruby by :
$ \curl -L https://get.rvm.io | bash -s stable –ruby
and check all the ruby version with stability
$ rvm list known
can also check details here : http://www.ruby-lang.org/en/downloads/
$ rvm install ruby 2.0.0-p247
Use when you want to download specific version or know this is stable.
There’s a fantastic RVM GUI called JewelryBox that I use to manage my Ruby versions
I think that is:
rvm all do gemset update
