Can't Install Ruby on Rails with Rvm on Ubuntu 13.04

Can't install Ruby on Rails with RVM on Ubuntu 13.04

There are some important packages your system needs before install rvm. Run at the terminal:

sudo apt-get install build-essential openssl libreadline6 libreadline6-dev \
curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-dev \
sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake \
libtool bison subversion nodejs

Then install rvm with:

curl -L https://get.rvm.io | bash -s stable --ruby

Now you need to put a setting in your .bashrc to add rvm to PATH for scripting. Run:

echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"' >> ~/.bashrc

Open a new terminal and test rvm.

Unable to install Ruby on Rails on Ubuntu 16.04 LTS

If you install rvm without sudo privileges, everything else should work as expected

If you have rvm installed, remove it using

rvm implode

or

rm -rf ~/.rvm

Then install rvm using

gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3
\curl -sSL https://get.rvm.io | bash -s stable

Then install ruby with

rvm install 2.3.0

Use whichever version you wanna install.

Now go ahead and install rails

gem install rails

Error on installing ruby rvm

You're trying to install it with apt-get. You probably installed ruby-rvm but since it's outdated it was installed broken. You probably have to delete it using synaptic or via sudo apt-get purge ruby-rvm command. You should NOT install rvm via apt-get. Read post from Ryan more careful. Correct command to install rvm is:

curl -L https://get.rvm.io | bash -s stable

Facing difficulty in Installation of Interactive Ruby shell and ruby in ubuntu 13.04 and getting started with rails

to use a gemset try writing
rvm use ruby_gemset_version

to check the rails version try to type rails -v

Using RVM on Ubuntu 12.04 to use Rails. The program 'rails' is currently not installed

You need to type source ~/.rvm/scripts/rvm before attempting to use Rails.

I believe the RVM installation suggests putting this line (or something similar) in your .bashrc.

Run the following command in Terminal:

echo "source \$HOME/.rvm/scripts/rvm" >> ~/.bashrc

This appends the line source \$HOME/.rvm/scripts/rvm to the end of the .bashrc file.

Doing so ensures that RVM is properly loaded each time you open up a terminal.

Can't find Ruby 1.9.2 after installing RVM

RVM is a version manager which enables you to decide which of multiple installed Ruby versions you want to use in your current shell session. RVM does this by providing a shell function named rvm which can be used to switch between versions in the current session. This changes environment variables, especially the GEM_HOME and PATH, to match the currently selected Ruby installation.

Every installed Ruby version can be selected by a specific identifier string. If you had a system-wide Ruby installation already before you installed RVM, that one should be referenced by the string system. The newly installed version in your case should be called 1.9.2.

To make RVM work as intended, it is necessary to load the rvm shell function into your shell. How to do this is described in the RVM Installation Documentation in section 2 - "Load RVM into your shell sessions as a function".

You can see if the shell function is correctly loaded when the command type rvm | head -n1 responds with:

rvm is a shell function

If not correctly loaded it will tell you something like this:

rvm is /home/someone/.rvm/bin/rvm

If you finally have it working you can switch your active Ruby version with commands like rvm 1.9.2 or rvm system. You can get a list of all Ruby versions and their identifier strings recognized by RVM by the command rvm list.

You can also specify which Ruby version shall be enabled in all new shell sessions from the beginning by issuing the following command once:

rvm --default 1.9.2
