Can not install Jruby using RVM

Question

When I run one of the following commands:

rvm install jruby-1.7.3

or

rvm install jruby

I get the following message:

Searching for binary rubies, this might take some time.

Installing requirements for ubuntu, might require sudo password.

Running 'apt-get --quiet --yes update' would require sudo.

Cowardly refusing to continue, please read 'rvm autolibs'.

Updating repositories

Missing required packages: git-core.

Cowardly refusing to continue, please read 'rvm autolibs'.

and

rvm --version

gives me

rvm 1.19.0 (latest) by Wayne E. Seguin , Michal Papis [https://rvm.io/]

Could anyone advise how to fix this?

Answer 1

The issue was fixed with just running:

rvm autolibs enabled

When I firstly run

rvm autolibs status

and the output was "disabled", where allowed modes are as follows:

• 0, disable, disabled - Limit RVM automation as much as possible.
• 1, read, read-only - Allow RVM to use package manager if found but do not install or fail if dependencies are missing.
• 2, fail, read-fail - Allow RVM to use package manager if found, fail if dependencies are missing. This is default.
• 3, packages, install-packages - Allow RVM to use package manager if found, install missing dependencies.
• 4, enable, enabled - Allow RVM to use package manager if found, install missing dependencies, install package manager (only OSX).
• brew, homebrew, osx_brew - Like 4 but forces use of Homebrew.
• port, macports, osx_port - Like 4 but forces use of MacPorts.
• fink, osx_fink - Like 4 but forces use of Fink.
• smf - Like 4 but forces use of SM Framework.

Answer 2

Looks like you might need to install git sudo apt-get install git

Answer 3

I got similar error when installing ruby

Missing required packages: git.

Cowardly refusing to continue, please read 'rvm autolibs'.

Take a look at the instructions on the following link, it may help you.

https://www.digitalocean.com/community/articles/how-to-install-ruby-on-rails-on-centos-6-with-rvm

Note that after installing rvm you probably have to install additional dependencies using following command before you install ruby (this is listed in the link)

yum install -y gcc-c++ patch readline readline-devel zlib zlib-devel libyaml-devel libffi-devel openssl-devel make bzip2 autoconf automake libtool bison iconv-devel

NOTE: For centos >= 5.4 iconv-devel is provided by glibc
