I'm trying to lookup help for Ruby methods in Textmate through the Ctrl+H shortcut, but I'm always getting this error:
/Users/tomdeleu/.rvm/rubies/ruby-1.9.2-p180/lib/ruby/site_ruby/1.9.1/rubygems.rb:388:in
bin_path': can't find gem rdoc ([">=

Platform:
MacOS X 10.6.8
RVM 1.6.20
Textmate 1.5.10 (1631)
TM_RUBY set to /Users/tomdeleu/.rvm/bin/rvm-auto-ruby
installed osx-plist update as detailed in the RVM integration docs
installed DrNic's Rails bundle
Ri works fine from the command-line (I ran "rvm docs generate" to install docs for 1.9.2).
I've searched around but can't find a solution. Can anyone help?
After a lot of searching (and asking) around, solved it by reinstalling both Textmate (including delete of all customizations), and Ruby 1.9.2 (through RVM). Afterwards I installed the osx-plist update + some bundles again. Note that the osx-plist update (as detailed here) should be done with system Ruby, not a Ruby 1.9, otherwise other errors occur. Also in Textmate make sure the PATH variable does not have a custom Ruby before your system Ruby.
With these settings, everything works fine now. Hopefully this is useful to anyone encountering this error in the future...

I was happily using Emacs's evernote-mode until stupidly removed OS X system ruby (I'm on Yosemite). Then I tried installing one via RVM (first tried 2.0 then 1.9), got all necessary gems, yet thing is still broken. Throws this message:
$HOME/.rvm/rubies/ruby-1.9.3-p551/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:54:in `require': cannot load such file -- oauth (LoadError)
from $HOME/.rvm/rubies/ruby-1.9.3-p551/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:54:in `require'
from $HOME/.rvm/rubies/ruby-1.9.3-p551/bin/enclient.rb:40:in `<main>'
Please help me to fix that
upd: I don't see the point of reinstalling system ruby (as people suggested) and then having it conflicting with those that I want to use via RVM. Ruby developers advise to use RVM. I symlinked my default Ruby to /usr/bin/ruby.
I seems that specific script uses something I don't have. I remember having hard time figuring out all dependencies and gems and installing them the first time I used that script and after hours of investigating it finally worked. But this time I got stuck.
I tried to run the script outside of Emacs and it runs with no errors (maybe that's not enough to find what's broken)
I tried to run irb and require modules one by one. It says => true until reaches require 'oauth/consumer'. I guess that's what's missing maybe? I run gem install oauth_consumer. It installed few gems, and now says => true for oauth/consumer in irb, the script though still doesn't work
i removed systems ruby once. i just had to go to the trash and put back everything i deleted and it worked for me. don't know how you "removed" your system ruby. besides, if you installed one with RVM then you have to tell RVM to choose and use/set a default ruby. because RVM won't install ruby 1.9.1 (rather a higher version which i think you did). So you have to set to that version.
Like this:
$ rvm --default use 2.1.5
don't forget to install oauth as well. Hope it helps.
After a couple of days of not doing pretty much anything on the ubuntu box, I decided to try out some ruby stuff. For this, I wanted to fire up pry. Unfortunately, I was presented with
Sorry, you can't use Pry without Readline or a compatible library.
Please gem install rb-readline or recompile Ruby --with-readline.
~/.rbenv/versions/2.1.1/lib/ruby/2.1.0/rubygems/core_ext/kernel_require.rb:55:in
`require': libreadline.so.5: cannot open shared object file: No such
file or directory -
~/.rbenv/versions/2.1.1/lib/ruby/2.1.0/x86_64-linux/readline.so
(LoadError)
Being quite new to linux in general, I figured I'd just do as it said, and install this rb-readline. The installation passes just fine, but doesnt seem to do anything at all. If I do gem list p, the package just doesn't appear.
So yeah, I just don't know what to do to get it working again, and the only thing I managed to find by searching was related to an installation without rbenv and had something to do with sudo etc.
Any ideas?
Without understanding the problem and following the advice in option 2 of the message:
Sorry, you can't use Pry without Readline or a compatible library.
Possible solutions:
* Rebuild Ruby with Readline support using `--with-readline`
* Use the rb-readline gem, which is a pure-Ruby port of Readline <==== Option 2
* Use the pry-coolline gem, a pure-ruby alternative to Readline
I added the gem into the Gemfile (as follows), bundled and pry was then available.
group :development, :test do
gem 'pry'
gem 'rb-readline'
end
I had this problem too. I am using rbenv and reinstalling ruby via
rbenv install -f 2.2.3
did fixed it for me. Of course you'd put in your respective version. -f forces the installation even though you already have that specific version installed. use rbenv global to find out what version you have installed and set.
I have some problem. But I don't want to add gem 'rb-readline'. So try it...
$ln -s /usr/local/opt/readline/lib/libreadline.8.0.dylib /usr/local/opt/readline/lib/libreadline.7.dylib
Do a sudo apt-get install libreadline-dev, seems like you're missing the readline shared library that pry is wanting. If it worked before, not sure why the library isn't there anymore.
I ended up doing rbenv uninstall, followed by rbenv install and re-installing all the gems, and got it back to working. Still no idea what caused it in the first place, but it works now.
SOLUTION:
You have the same problem, you have to compile Shoes (https://github.com/shoes/shoes/wiki/Building-Shoes-on-Linux)
if rake doesn't work, try to install ruby 1.9.2 through rvm.
I recently started to learn Ruby, and i came across this library.
I tried to install it using the .run file provided by the official site, but it seems like it's broken. If i run it, it tells me:
./shoes-3.1.0.run: 1: eval: ./shoes: not found
And yes, after extracting the file, i found a folder which didnt contain it.
The only runnable thing i find is HacketyHack, which worked, but I prefer to use my own editor.
Since I have just started to learn Ruby, I'm not comfortable with playing with the .rb files to get it working outside of HH. I also tried to install it via apt-get, but after running 'shoes', all i get is:
no such file to load -- rubygems
Compiling from source code didn't work for me. Is there anything else I can try, or am I doing something terribly wrong?
The problem seems to be your ruby version. ruby in the apt repositories is version 1.8.7 which is quite old. Try apt-get install ruby1.9.1
If that doesn't work, I would recommend using rvm. Install, then simply rvm install ruby-2.0.0 which is the latest version, then rvm use 2.0.0. If shoes doesn't work under any of these versions, it's probably a bug in shoes.
guys. I am developing a Chinese application with rails. Now I want to input some Chinese characters in rails console but cannot do that, either in irb.
Any guys who have the experience to solve this problem? I would appreciate your help!
Based on #Jimmy-Huang's answer, these are the steps I followed on Mac Leopard using rvm and ruby 1.9.2:
rvm package install readline
rvm remove 1.9.2
rvm install 1.9.2 --with-readline-dir=$rvm_path/usr
That resulted in some errors, particularly when trying bundle install:
uninitialized constant Gem::SilentUI
It turned out that's due to an older version of bundler and this gets rid of it:
gem install bundler
I found the solution for me, it need to re-compile the readline. And now I can input non-ASCII characters!
Because I am using rvm, so I found this article to teach you how to re-compile readline under rvm. http://rvm.beginrescueend.com/packages/readline/
And for someone who is not using rvm, maybe you can follow this post and have a try:
http://henrik.nyh.se/2008/03/irb-readline
By the way, ruby-1.9.2 irb already supports non-ASCII inputing.
Check out the pack method on array:
http://ruby-doc.org/core-1.8.7/classes/Array.html#M000287
I think you'd want:
[111 ,222, 333].pack(U*)
Here is an interesting discussion on the subject had with Matz:
http://www.ruby-forum.com/topic/134919
I've recently installed Ruby 1.9.1 on Windows 7, and apparently it doesn't come with the standard ri documentation. So when I do 'ri Array', I get:
C:\>ri Array
Nothing known about Array
Is there a way I can install this documentation so that the above works?
In case people on other platforms need to install their ri docs (like I did). This article gives the why and the how:
http://jstorimer.com/ri.html
The command is:
gem rdoc --all --ri --no-rdoc
If you are using rvm you should rvm docs generate (or just rvm docs generate-ri)
See this info (2011August) about rvm and ri
None of the proposed solutions worked for me. In the end the solution I found was super simple, so I'll leave it here. (I'm running ruby 2.2.4 on win7 x64 in case that's relevant)
(captain obvious alert: ruby must be installed and in your PATH)
-open cmd
-$ gem install rdoc-data
-$ rdoc-data --install
And you're set! test that it worked by running:
-$ ri Array It should give you all the lovely documentation for the class!
Hope this helps!
ps. I just noticed that this is the solution that Luis Lavena proposed in a comment, but his comment wasn't clear to me so I had continued searching. Basically this is the same solution but explained more clearly so that that doesn't happen to anyone else :)
Cheers!
Things are still largely the same with Ruby Installer 2.4.1.2 (year 2017). If I run ri Array, it shows Array < Object and nothing else. If I run ri "Array#each", I get the familiar "Nothing known..." message. In short, the ri-format documentation on Ruby core and standard libraries are missing.
Here's how I got my copy of core/stdlib ri-documentation. Of course, Ruby must be installed prior to this.
Get ruby's source code that most closely matches my version from their Github releases page.
Extract the .zip or .tar.gz archive to some folder
Open cmd.exe/Powershell, cd to that folder and run rdoc --all --ri
This command parses .c files, .rb files, and a few other file types in the current directory recursively and generates ri-documentation to ~/.rdoc directory.
Took about 5 minutes on my laptop with i7-3520M processor to complete, with no errors.
Delete the archive and the directory containing the source code because we don't need them anymore.
Now if you try running ri Array or ri "Array#each" you'll get the documentation in all its glory.
tl;dr
Run rdoc --all --ri on directory containing source code for same ruby version as your installed version.
Appendix Z: Comments on other answers
The rvm docs generate-ri could work, but you have to use Cygwin or Ubuntu on Windows (if on Windows 10) to use rvm.
gem rdoc --all --ri --no-rdoc installs ri-documentation for all your gems. It doesn't install the core/stdlib documentations.
gem install rdoc-data followed by rdoc-data --install only works for Ruby versions up to 2.3.0.
Seems you have installer Ruby 1.9.1 distributed by the RubyInstaller project.
You can use the Windows Help Files (CHM) that came with the installer instead of the ri documentation.
The problem of the RI documentation is that some versions of RDoc have problems generating it and also generated more than 10 thousands files which slowed down the installers considerably.
RVM does not automatically generate and install each Ruby's ri / rdoc documentation. You can generate using the following command:
rvm docs generate
All the Ruby Docs are at http://www.ruby-doc.org
So the array documentation is at:
http://ruby-doc.org/core/classes/Array.html
Never tried it on windows but because its saying Nothing Known about X its not that its not installed just not got anything there.
Try installing a gem as you can then ri GEM_CLASS as that should provide defentions, should let us see if its missing documentation or if ri's not looking in the right place
You might run into this issue under Docker. The official docker images come with no documentation, and apparently disable installing gem documentation.
If image's and system ruby versions match (specifically, RbConfig::CONFIG["ruby_version"], which is e.g. 2.6.0 for ruby-2.6.1), you can:
# apk add ruby-doc
# cp -r /usr/share/ri /usr/local/share/ri
