I have a clean install of mountain lion 10.8.2 and have installed rbenv and gem installed wkpdf. When I try and run wkpdf, I get the following message:
xxxx-MacBook-Pro:~ xxx$ wkpdf --help
Cannot load RubyCocoa library
wkpdf requires that RubyCocoa is installed, which is shipped by default since
Mac OS X 10.5. If you use Mac OS X 10.4, you have to install RubyCocoa
yourself from http://rubycocoa.sourceforge.net/HomePage
Is possible to run wkpdf in the rbenv environment? (I have posted a similar question on rbenv github but have not yet had a response)
It's possible that you have installed wkpdf in a Ruby version other than "system" one. Check your active version with rbenv versions.
When installing and using wkpdf, ensure that you've selected the "system" version:
RBENV_VERSION=system gem install wkpdf
Also when using the gem, you must use "system" version as well for executing code in your project, or the gem won't be found.
It seems that because of the nature of how wkpdf works, it relies on executing within system Ruby on OS X.

When I want to install compass with gem install compass, I occurred with this error:
YAML safe loading is not available.
Please upgrade psych to a version that supports safe loading (>= 2.0).
what The cause of this error and how can I solve the problem?
It sounds like the psych gem needs to be updated. Try running gem install psych and then gem update psych.
Suggested by looking at the psych readme file here: https://github.com/ruby/psych/blob/master/README.md
EDIT: you might also have to update your version of ruby. This depends on how you have installed ruby, but #ewerx has one suggestion in their answer.
To resolve this I first upgraded Ruby from 2.0.x to 2.4.2 (https://gorails.com/setup/osx/10.12-sierra):
rbenv install 2.4.2;
rbenv global 2.4.2
Then updated gems:
sudo gem update --system;
gem update
It may be sufficient to just update gems.
The following part of the post on https://gorails.com/setup/osx/10.12-sierra solved my issue.
We will be setting up a Ruby on Rails development environment on macOS 10.12 Sierra.
Older versions of OS X are mostly compatible so follow along as far as you can and then Google search for any problems you run into. There are plenty of people who have documented solutions for them.
Installing Homebrew
First, we need to install Homebrew. Homebrew allows us to install and compile software packages easily from source.
Homebrew comes with a very simple install script. When it asks you to install XCode CommandLine Tools, say yes.
Open Terminal and run the following command:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Installing Ruby
Choose the version of Ruby you want to install:
Now that we have Homebrew installed, we can use it to install Ruby.
We're going to use rbenv to install and manage our Ruby versions.
To do this, run the following commands in your Terminal:
brew install rbenv ruby-build
Add rbenv to bash so that it loads every time you open a terminal
echo 'if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi' >> ~/.bash_profile
source ~/.bash_profile
Install Ruby
rbenv install 2.5.1
rbenv global 2.5.1
ruby -v
I have been having some issues with my Ruby and Gem environments and wanted to clean them all out and start over. So I removed all my ruby's in rvm (rvm 1.13.8 (stable)) which left me with the stock Ruby 1.8.6 and Gem 1.0.1. I thought about removing these as well but everything I read said they should be fine. Anyway I went to install Ruby 2.0 but RVM has 1.9.3 as the most current and I was wondering if its because I am running 10.5.8 on a G4 MDD and if there is a possibility of being able to install it. My MacBook Pro running 10.8 was able to install it.
$ rvm list known
# MRI Rubies
[ruby-]1.8.6[-p420]
[ruby-]1.8.7[-p358]
[ruby-]1.8.7-head
[ruby-]1.9.1[-p431]
[ruby-]1.9.2-p180
[ruby-]1.9.2-p290
[ruby-]1.9.2-p318
[ruby-]1.9.2[-p320]
[ruby-]1.9.2-head
[ruby-]1.9.3-preview1
[ruby-]1.9.3-rc1
[ruby-]1.9.3-p0
[ruby-]1.9.3-p125
[ruby-]1.9.3-[p194]
[ruby-]1.9.3-head
ruby-head
You need to update RVM, the versions are part of the update:
rvm get head
rvm list known | grep 2.0.0
which gives:
[ruby-]2.0.0-rc1
[ruby-]2.0.0-rc2
[ruby-]2.0.0[-p0]
rbx-2.0.0-rc1
I installed ruby-1.9.3 by my homebrew, so it locate on /usr/local/Cellar/ruby/1.9.3-p286/.
After installed Rails by rvm, I do command bundle install but the bundles were all installed to the /Library/Ruby/Gems/1.8/gems which is an old-version ruby installed with my OS X.
What can I do to let the bundles install in the right place?
Try this
$ rvm use 1.9.3--system
Use either rvm or rbenv to manage different versions of ruby. You could also consider JewelryBox, which does pretty much the same thing, but with a prettier GUI.
I want to use rails console and I'm using ubuntun 11.10 currently I have found the issue
error is something :
completion.rb:9:in `require': no such file to load -- readline (LoadError)
and I found a way to solve it:
http://blog.jasonmeridth.com/2010/11/25/readline-error-with-rvm-and-rails-3.html
but seems in ubuntu 11.10 the libreadline5-dev is missed and it is replaced with version 6
I installed version 6 and also I get the version 5 from
https://launchpad.net/ubuntu/oneiric/i386/libreadline-gplv2-dev/5.2-9ubuntu1
but yet if I try to run following code :
ruby extconf.rb
I'll get following lines :
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
the "no"s part is my problem , so how can I solve this problem?
Ubuntu 11.10 uses newer readline library which not in sync with the readline package offered by rvm
To solve this (assuming you use single-user installation of rvm) do:
1) ensure you have installed ubuntus readline and editline dev packages
sudo apt-get install libreadline6 libreadline6-dev
2) configure ruby's readline extension to use the systems libs, not rvm's packages
rvm pkg uninstall readline
cd ~/.rvm/src/ruby-1.9.2-p290/ext/readline
ruby extconf.rb --with-editline-dir=/usr/ --with-readline-dir=/usr/
make
make install
3) go to your project and start up the rails console
Tip: You can call
rvm requirements
to see what ubuntu packages should be installed to use rvm ruby
You have to install the readline development packages before compiling ruby. Just run
sudo apt-get install libreadline6-dev
Alternative (as suggested in the article you linked) you can use RVM to get the appropriate readline sources by running
rvm package install readline
Edit: Once you've installed the readline packages from source, you can install your rubies like this
rvm install 1.9.3 --with-readline-dir="$rvm_path/usr"
If you alredy have installd a specific ruby, just use reinstall instead on install.
I'm a beginner programmer and I'm trying to get the rails server to run on OS X Lion. When I type "rails server" into the command line, I get this error:
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems.rb:777:in `report_activate_error': Could not find RubyGem rails (>= 0) (Gem::LoadError)
from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems.rb:211:in `activate'
from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems.rb:1056:in `gem'
from /usr/bin/rails:18
What do you think a solution to the problem is? Any help you can provide would be greatly appreciated. Thanks!
You need to install the rails gem. You could probably do this by running bundle install inside that project.
Have you installed the Rails Gem?
gem install rails
Then do a gem list to see if Rails is in there.
It's also important that you be in the proper directory. So if you keep all of your apps in /apps/ make sure you are in /apps/my_app before calling the server command.
The Ruby bundled with OS X is too old for Rails 3.
I would recommended using 'rvm' to install the latest stable version of ruby-1.9.2-p260
Since installing ruby requires some compilation, make sure you have a gcc installed. You can install XCode to get an usable gcc.
To install rvm, you need bash, git and curl.
RVM: http://beginrescueend.com/
After that, you can use
gem install rails
Enjoy!
The Lion Server looks at a non-default path for the gem file
For example have a look at the first line of /usr/share/devicemgr/backend/devicemgrd:
#!/usr/bin/env GEM_HOME=/usr/share/devicemgr/webserver/gems GEM_PATH=/usr/share/devicemgr/webserver/gems RAILS_ENV=production /usr/bin/ruby
So to install the missing gems, make sure to install them at the required path:
sudo GEM_HOME=/usr/share/devicemgr/webserver/gems gem install rails
