I wish to use Qt on Windows 10 and am currently trying to use the qtbindings gem.
When trying to require 'Qt' I get the following error:
C:/Ruby26-x64/lib/ruby/gems/2.6.0/gems/qtbindings-4.8.6.5-x64-mingw32/lib/Qt4.rb:25:in `require': cannot load such file -- 2.6/qtruby4 (LoadError)
I tried uninstalling the gem and reinstalling it just in case but no luck.
I am using Ruby 2.6.5p114 and qtbindings 4.8.6.5. I made sure that Ruby and the gems are all in the path environment variable.
Am I missing a step or am I using out of date versions?

I am using Apache with FastCGI to run a ruby application. I have installed the apache fcgi module and also the Ruby fcgi gem.
When I run the fcgi script 'search.fcgi' like so
ruby search.fcgi
It runs successfully. However when starting Apache I get the following error in my log file when it tries to run the same script:
/usr/local/rvm/rubies/ruby-2.1.8/lib/ruby/site_ruby/2.1.0/rubygems/core_ext/kernel_require.rb:54:in `require': cannot load such file -- fcgi (LoadError)
from /usr/local/rvm/rubies/ruby-2.1.8/lib/ruby/site_ruby/2.1.0/rubygems/core_ext/kernel_require.rb:54:in `require'
from /home/user/fcgi/search.fcgi:13:in `<main>'
Line 13 in search.fcgi is simply
require 'fcgi'
It appears as though when running through Apache it is unable to detect the installed gem. I have loaded irb and and run require 'fcgi' which returns true.
Am I missing something here? Some path or config item I need to set?
My problem was caused by the fact that Ruby was installed using RVM. There was some issue with the script from apache accessing some parts of the RVM instillation. The solution was to remove the RVM ruby install and reinstall ruby from source.
I'm new to ruby. I removed ruby 1.9 with sudo apt-get purge ruby and then
I installed ruby 2.3.0 using ruby-install. But I got the following error
<internal:gem_prelude>:4:in `require': cannot load such file -- rubygems.rb (LoadError)
from <internal:gem_prelude>:4:in `<internal:gem_prelude>
when running rspec my_script.rb.
Still can't fix this after googling! Anyone can help me out?
It seems that the rspec binary was only installed for your previous ruby version. Therefore it is found, but not guaranteed to work.
I'd recommend to use something like rvm (https://rvm.io/) or rbenv (https://github.com/rbenv/rbenv). Both of them can easily handle different ruby versions while maintaining dependencies (e.g. different load paths, different gem versions, etc.). I'd even use rvm if there is only one single ruby version installed on a system.
I'm new on Rails and Ruby
I install Ruby with the tool provided by rubyInstaller and it work fine
Then i used gem to downlaod Rails 4
I tried to downlaod it
gem install rails
and it work
Then my prompt windows ask me to write this:
bundle install
And it downloaded a lot of new gem
I maked a new app called "App" with rails with this command
rails new App
And it worked.But when a point the directory of this new app and write this command
rails server
It give me this error:
C:/Ruby22/lib/ruby/gems/2.2.0/gems/nokogiri-1.6.6.2-x86-mingw32/lib/nokogiri.rb: 29:in `require': cannot load such file -- nokogiri/nokogiri (LoadError)
there are a lot of other thing but i think that this is the problem.
What i can do?
WIndows 8.1 x64
Ruby 2.2.2 x32
You need to include nokogiri in your Gemfile
I'm having trouble understanding the following error with Ruby's Rake.
C:\>gem install rake
Successfully installed rake-0.8.7
1 gem installed
Installing ri documentation for rake-0.8.7...
Installing RDoc documentation for rake-0.8.7...
C:\>rake
C:/Ruby192/lib/ruby/1.9.1/rubygems.rb:340:in `bin_path': can't find executable r
ake for rake-0.8.7 (Gem::Exception)
from C:/Ruby192/bin/rake:19:in `<main>'
Running Ruby 1.9.2 for Windows.
Edit: Installing from source yields:
C:\Documents and Settings\XPherior\Desktop\rake-0.8.7\rake-0.8.7>ruby install.rb
<internal:lib/rubygems/custom_require>:29:in `require': no such file to load --
ftools (LoadError)
from <internal:lib/rubygems/custom_require>:29:in `require'
from install.rb:3:in `<main>'
The second error, where you have installed into C:\Documenets And Settings\ is occurring because you cannot install ruby into a folder with a space in the path. It should be installed into c:\Ruby\ c:\Ruby#.#.#\ if you want the version # in the path, or something along those lines.
for the first error: there is a bug in the rubyinstaller.org version of ruby 1.9.2, which is causing this by running "gem install rake".
you can read about the error you're getting, here: http://redmine.ruby-lang.org/issues/show/3677
there are a couple of ways to fix this error:
re-install ruby v1.9.2 and don't run "gem install rake". rake v0.8.7 is built into the ruby v1.9.2 installation, so you don't need to re-install it.
if you do want to manually install it, you can delete the ruby.gempspec file from your ruby installation. this file is located at (rubyinstalldir)\lib\ruby\gems\1.9.1\specifications
either of these options will fix the problem for you.
i'm not sure which is "better" off-hand... it may be necessary to delete the gemspec file and reinstall rake, to support updates and new versions in the future. i'm not sure, though. we'll find out once rake is updated and we need to install a new version. or, perhaps, the issue will be fixed in the ruby installation by then, and we'll just need to update our ruby install.
I've run into your both errors.
For the first one. Try the solution post at here http://betterlogic.com/roger/2010/11/ruby-1-9-2-rake-woe/.
And for the second error, it's causes by a library update by the ruby 1.9. From the Programming Ruby 1.9, "ftools have been removed (and replaced by fileutils)." I'm not pretty sure but at least that's an explanation.
I am just starting to learn ruby. It seems that the default gems install path is not part of Ruby. Is this normal behavior? How can I set the default ruby path? Example:
[11:53:33]wuntee:/Library/Ruby/Gems/1.8/gems/packetfu-1.0.0/examples$ sudo ruby arphood.rb
Fetching the oui.txt from IEEE, it'll be a second. Avoid this with arphood.rb <filename>.
arphood.rb:30:in `require': no such file to load -- packetfu (LoadError)
from arphood.rb:30:in `arp_everyone'
from arphood.rb:51
As you can see packetfu is installed in /Library/Ruby/Gems/1.8/gems/, but ruby cant find it...
that's because you're not in the directory where packetfu.rb file lies and there's no require 'rubygems' to add the gems paths in your script
