Question

I'm getting this error:
Could not find i18n-0.6.1 in any of the sources
Run bundle install to install missing gems.
When i try to run bundle install, i get this:
-bash: bundle: command not found
I have googled and tried to solve this for a while now with no hope. Please help.

Answer 1

Don't mess with your PATH.
Just use rbenv and ruby-build to manage and install your ruby version(s).
And then install the bundler gem and rehash.
Install rbenv (if you haven't already) as follows:
$ brew update
$ brew install rbenv ruby-build
Initialize rbenv as follows:
$ rbenv init
Install ruby-build to compile and install different versions of Ruby on UNIX-like systems:
brew install ruby-build
Install a specific ruby version, e.g., 1.9.3-p551:
$ RUBY_VERSION=1.9.3-p551
$ ruby-build $RUBY_VERSION $HOME/.rbenv/versions/$RUBY_VERSION
Verify it worked:
$ ruby --version
ruby 1.9.3p551 (2014-11-13 revision 48407) [x86_64-darwin14.0.0]
Set that version to be the global/default Ruby version:
$ rbenv global 1.9.3-p551
Install bundler:
$ gem install bundler
Fetching: bundler-1.7.11.gem (100%)
Successfully installed bundler-1.7.11
1 gem installed
Update rbenv:
$ rbenv rehash
Now, bundler will be available in the version of Ruby (1.9.3-p551) that you just installed.
Verify RubyGems Environment:
$ gem env

Answer 2

try to run
gem env
and then you will get something like this:
RubyGems Environment:
- RUBYGEMS VERSION: 1.8.23
- RUBY VERSION: 1.9.3 (2013-06-27 patchlevel 448) [x86_64-darwin12.5.0]
- INSTALLATION DIRECTORY: /usr/local/Cellar/ruby193/1.9.3-p448/lib/ruby/gems/1.9.1
- RUBY EXECUTABLE: /usr/local/Cellar/ruby193/1.9.3-p448/bin/ruby
**- EXECUTABLE DIRECTORY: /usr/local/Cellar/ruby193/1.9.3-p448/bin**
- RUBYGEMS PLATFORMS:
- ruby
- x86_64-darwin-12
- GEM PATHS:
- /usr/local/Cellar/ruby193/1.9.3-p448/lib/ruby/gems/1.9.1
- /Users/madhava/.gem/ruby/1.9.1
- GEM CONFIGURATION:
- :update_sources => true
- :verbose => true
- :benchmark => false
- :backtrace => false
- :bulk_threshold => 1000
- REMOTE SOURCES:
- http://rubygems.org/
Just add the executable directory to your PATH variable like this:
echo PATH=/usr/local/Cellar/ruby193/1.9.3-p448/bin:$PATH >> ~/.bash_profile
Reload your terminal to apply the changes and you will be set!

Seems with Sierra, you need to use this to get bundler installed:
sudo gem install bundler -n /usr/local/bin
Reference here refers to how El Cap introduced "SIP (System Integrity Protection)."

Answer 4

I am on Mac OS X Maverics (10.9.2)
Currently my ~/.profile file reads as follows:
# MacPorts Installer addition on 2014-02-23_at_17:28:39: adding an appropriate PATH variable for use with MacPorts.
export PATH=/opt/local/bin:/opt/local/sbin:$PATH
# Finished adapting your PATH environment variable for use with MacPorts.
source /usr/local/bin/virtualenvwrapper.sh
. /sw/bin/init.sh
And my PATH variable ($PATH) is set to
/sw/bin:/sw/sbin:/opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin
This is what worked for me.
First I installed bundler using:
gem install bundler
However I got error:
ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory.
Hence I ran sudo gem install bundler and that installed bundler successfully
After that when I ran gem env I got the Executable Directory set to /usr/bin which is already part of my PATH variable. Hence I didn't make any changes to ~/.profile file.
and now I am successfully able to run bundle install.
If the path listed in Executable Directory is not included in your $PATH variable or ~/.profile file, you will have to include it.

Note that if you're using rbenv, you should probably just rbenv rehash and not mess with your PATH
