So I was trying to install redmine on an apache2 server on Ubuntu.
Between multiple atemps to install a plugin, I "accidentaly" deleted /usr/bin/ruby1.8.
Now I get this error when I try to launch redmine with ruby2.0 (even after a rvm install 1.8) :
*** ERROR ***: Cannot execute /usr/bin/ruby1.8: No such file or directory (2)
What should I do to have this executable back ?
Thanks for your help
I suspect ruby1.8 was the already installed system ruby; can check with dpkg --get-selections | grep ruby . If this is the case, I would uninstall ruby 1.8 from rvm and then reinstall the system ruby through apt.
Once that's been cleared up, and you have a /usr/bin/ruby1.8 again, check/manage your available rubies through rvm:
rvm list
rvm use <ruby version>
etc.

First of all, I doubt that RVM may not be updated to support this version of Ruby. As I know the following version is supported, you can version by following command and response should match.
rvm --version
1.29.7
If you have updated version then I will do the following to check if RVM has also the same version of ruby installed.
I will check the content of my project root folder's following file
cat .ruby-version
If it has mention same, as rvm is also complaining that I will run the following command on rvm to check if this ruby is really installed in RVM
rvm list
It will show a list of rubies installed and it should include 2.6.1 in the end. If you can't see this list then you probably need to install using the following command
rvm install "ruby-2.6.1"
If it is showing than can you try the following command and see what result comes
rvm use 2.6.1
If all good, then try the following command to see which ruby is being used
which ruby
response must include .rvm/rubies/ mean you are using .rvm ruby otherwise, you may using the system built in ruby.
Just wrote may help you to diagnos issue.
Are you using rbenv? If so, I'd recommend running rvm implode as described here.
if you are using rbenv
see if you have it available in your list :
rbenv install --list | grep 2.6.1
if not, fetch it
cd ~/.rbenv/plugins/ruby-build && git pull && cd -
now if you try again
rbenv install -l | grep 2.6.1
so just run the installation command:
rbenv install 2.6.1

I installed ruby and rails and other gems in ubuntu via terminal using rvm
After installation i checked the version of ruby and rails.
Later i closed the terminal. now I am not able to find ruby in it.
I am new to ruby and ubuntu as well. I am sure its installed . But after closing the terminal when I open it again and type "ruby -v"
I get this :
ubuntu#ubuntu:~$ ruby -v
The program 'ruby' can be found in the following packages:
* ruby
* ruby1.8 (You will have to enable component called 'universe')
Try: sudo apt-get install <selected package>
ubuntu#ubuntu:~$
I would highly suggest using rbenv instead of rvm for Ruby these days.
A guide on how to install it is located here: https://gorails.com/setup/ubuntu/14.10
The Ruby will then be installed in the .rbenv directory that is located in your $HOME folder.
To answer your question on where rvm installs it, it is installed into .rvm folder in your $HOME
I'm trying to get ruby 2.1.4 installed via rbenv for a client project.
Though previously I've been able to install ruby versions through rbenv, after upgrading to Yosemite, I keep getting the following error:
rbenv: no such command 'install'
After digging around, I saw lots of tips about how "install" comes from the ruby-build plugin, which is installed via homebrew:
which ruby-build
/usr/local/bin/ruby-build
I installed rbenv via Homebrew, but when I try use which rbenv, I get:
rbenv () {
typeset command
command="$1"
if [ "$#" -gt 0 ]
then
shift
fi
case "$command" in
(rehash|shell) eval `rbenv "sh-$command" "$#"` ;;
(*) command rbenv "$command" "$#" ;;
esac
}
I have run brew update and brew upgrade rbenv ruby-builder, and it tells me everything is up to date.
Below is my full $PATH:
zsh: no such file or directory: /usr/local/var/rbenv/shims:/usr/local/var/rbenv/shims:/usr/local/bin:/usr/local/sbin:/Users/dannycox/.rbenv/shims:/Users/dannycox/.rbenv/shims:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/usr/local/go/bin:/Users/dannycox/.rbenv/shims:/Users/dannycox/.rbenv/bin
UPDATE: Found another answer with a little deeper digging on github that showed signs of promise, but failed to solve the issue with rbenv. https://github.com/sstephenson/rbenv/issues/610#issuecomment-56240018
I believe 2.1.4 is now installed on my machine, but it installed here:
Successfully installed ruby 2.1.4 into /Users/dannycox/.rubies/ruby-2.1.4
As a result, my bundler won't work with the new ruby 2.0 version and I get the following error when I try to gem install bundle:
Fetching: bundler-1.7.6.gem (100%)
ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory
Still need help to identify why ruby-build isn't playing nice with rbenv...
Make sure to install optional step 5 in the instructions:
git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
Install ruby-build, which provides the rbenv install command that simplifies the process of installing new Ruby versions.
I had similar problem, and trace the problem to ruby-build. So i updated the homebrew and reinstall the ruby-build
> brew update
> brew reinstall ruby-build
Find the ruby version
> brew ls -v ruby-build | grep 2.1.4
then install intended version ruby again
> rbenv install 2.1.4
From your perms error I think you are trying to install to the system ruby, which is the one that comes with Apple OSX. You want to use rbenv to install your own ruby and install gems into that.
Read - https://github.com/rbenv/ruby-build#readme
And use the
rbenv versions
command to show what instance of ruby you are about to install the gems into. If it's system then you need to install your own ruby instance and then use that ruby for gems.
I have had rails installed and almost working. Was working on a solution to another problem with I accidentally closed the bash window. So I reopened it, and now I am unable to use rails at all and it's telling me that rails isn't installed. So I ran gem install rails --no-ri --no-rdocand now I get the following:
ERROR: While executing gem ... (Errno::EEXIST)
File exists # dir_s_mkdir - /usr/local/Cellar/ruby/2.1.1_1/lib/ruby/gems`
How do I correct this error?
I just removed the broken gems, site_ruby and vendor_ruby symlinks from the /usr/local/Cellar/ruby/2.1.1_1/lib/ruby/ folder and now everything seems to work fine.
I just added a gems/ directory here /usr/local/lib/ruby/ and that solved the issue.
for a temporary solution, you can mkdir -p /usr/local/Cellar/ruby/2.1.1_1/lib/ruby/gems/2.1.0 to solve.
When you open your bash window (called the "terminal window" or "console"), what folder ("directory") are you in? Find out with:
$ pwd
Navigate to the folder where you created your Rails project using the Unix cd command, for example:
$ cd workspace/learn-rails
If you are using RVM, make sure you have selected the correct gemset:
$ rvm gemset list
gemsets for ruby-2.1.1 (found in ...)
(default)
global
=> learn-rails
Then see if Ruby and Rails are installed:
$ ruby -v
ruby 2.1.1p76 (2014-02-24 revision 45161) [x86_64-darwin13.0]
$ rails -v
Rails 4.1.0
Refer to the article Install Ruby on Rails for help. If you haven't followed all the steps in the article, you may have problems, especially if you followed some of the inaccurate instructions found elsewhere on the web.
I was recently in this wormhole. It seems like Homebrew's ruby installation has an issue with soft links and uses version 2.1.1. I couldn't "gem install" anything without getting the annoying "File exists # dir_s_mkdir" error. Even tried MacPort and that was a nightmare.
First uninstall ruby via
brew uninstall ruby
or
port uninstall ruby
And follow the instruction on https://rvm.io/rvm/install to install ruby
\curl -sSL https://get.rvm.io | bash -s stable --ruby
It might then complain about ruby-2.0.0-p353 not installed
To install do:
rvm install ruby-2.0.0-p353
Then run the rvm install script. Your "gem install << whatever >>" should now work
This fixed the issue for me (Homebrew on a Mac, Ruby 2.1.3):
$ brew reinstall ruby
$ brew unlink ruby && brew link ruby
the same issue. I just remove dir_s_mkdir, then pod install. it works for me!
My environment is rails 3.1, ruby 1.9.2, rvm, Xubuntu 11.10.
When I try to run the rails console within an app, I am getting require errors pointing at readline.
So I am trying to install readline as a package within RVM, but this is the error I am getting:
Applying patch '/home/rob/.rvm/patches/readline-6.2/patch-shobj-conf.diff'...
ERROR: Error running 'patch -p0 -f < /home/rob/.rvm/patches/readline-6.2/patch-shobj- conf.diff', please read /home/rob/.rvm/log/readline/patch.log
ERROR: Patch /home/rob/.rvm/patches/readline-6.2/patch-shobj-conf.diff did not apply cleanly... back to the patching board :(
The log contains

patching file support/shobj-conf
Hunk #1 FAILED at 157.
1 out of 2 hunks FAILED -- saving rejects to file support/shobj-conf.rej
I've tried
$ rvm pkg install readline
$ rvm remove 1.9.2
$ rvm install 1.9.2 --with-readline-dir=$rvm_path/usr
And
$ cd $HOME/.rvm/src/ruby-1.9.2-p0/ext/readline
$ ruby extconf.rb
$ make install
The latter gives me
checking for tgetnum() in -lncurses... yes
checking for readline/readline.h... yes
checking for readline/history.h... yes
checking for readline() in -lreadline... no
checking for readline() in -ledit... no
checking for editline/readline.h... no
Running 'rails server' works, so I think the problem is just with readline.
Can anyone point me in the right direction.
Ran into the same problem on Ubuntu 10.0.4 and managed to fix it with:
rvm uninstall 1.9.2
sudo apt-get install libreadline-dev
rvm install 1.9.2 --with-readline-dir=/usr/include/readline
I've reinstall ruby 1.9.2 pointing at my system version of readline using this command:
rvm install 1.9.2 --with-readline-dir=/usr/include/readline
That seems to have fixed my problem and everything is now working.

Also worth noting that a matching issue exists on the rvm github site and it should be fixed soon:
https://github.com/wayneeseguin/rvm/issues/515
Ubuntu 11.10.
For me the following worked:
First install rvm.
Then install everything from rvm requirements
Then install 1.9.3 or whatever.
