I installed the ruby-processing gem using:
$ sudo gem install ruby-processing
When I try to run ruby-processing's rp5 command, this is the output I get:
rp5 run twitter_emotion_graphs.rb
No command 'rp5' found, did you mean:
Command 'rpm' from package 'rpm' (main)
Command 'rpl' from package 'rpl' (universe)
rp5: command not found
Here's the context for more information (have a look at the README) :

On some systems (e.g., Debian) the path where the gem executables are installed to are not in the $PATH. Dependingmon your distribution, that path is on a different location, on Debian with the system Ruby, it is at /var/lib/gems/1.8/bin. To add that to the system's $PATH, put something like this into a new file in /etc/profile.d/rubygems.sh
export PATH="$PATH:/var/lib/gems/1.8/bin"
Make sure the executable is on your path. You may have to restart your terminal for everything to refresh.

I have installed GO, setup the paths but when i run a file i get this error:
error!! exec: "sqlboiler": executable file not found in $PATH
exec: "sqlboiler": executable file not found in $PATH
exec: "sqlboiler": executable file not found in $PATH
exit status 3
What is going wrong?
The installation instructions are good, https://go.dev/doc/install. However, for me un Ubuntu 20.4 in wsl2, the suggested path for the binaries wasn't enough. Only go and gofmt are added to /usr/local/go/bin.
I did add the below to my .bashrc, since go install puts the binaries in this location on my system.
export PATH="$HOME/go/bin:$PATH"
Note, that the path to the binaries may differ on your system, so you have to adjust it accordingly.
Any binary you install with go install that is added to this path will be available to your shell afterwards.
For example:
$ go install github.com/volatiletech/sqlboiler/v4#latest
$ go install github.com/volatiletech/sqlboiler/v4/drivers/sqlboiler-psql#latest
$ whereis sqlboiler
sqlboiler: /home/blue/go/bin/sqlboiler
Potentially, you also need some database packages to your system. I am not sure on this any more. For example, you could add some Postgres libs if you are using Postgres. You have to see if it works without.
apt-get install postgresql-client-common postgresql-client-12
How to properly install GO with paths and all?
Install Go with the installer (Windows) or archive (extract into /usr/local on Linux/Mac).
When installing from archive, manually add the directory path where the go binary is located (/usr/local/go) to PATH.
Set GOPATH to a directory path wherein to contain bin, pkg and src sub-directories.
Add ${GOPATH}/bin to PATH.
What is going wrong?
The program you are running is trying to run the executable sqlboiler, which cannot be found in any of the directories specified in PATH.
I have a Ruby Script that when I run in the shell it works (as user):
/home/user/wpscan/$ ruby ./wpscan.rb -u www.mysite.com
However, I'd like to automate this with a function that I created with Python. Here is the python script:
#!/usr/bin/python
import os
wpscan_env = "/wpscan/"
os.chdir(os.environ['HOME'] + wpscan_env)
os.system("ruby ./wpscan.rb -u www.mysite.com")
Notice that the Python script is in a different folder, home/user/python/first.py and this is why I do the os.chdir() function. When I go back to the shell and type:
/home/user/python/$ python first.py
This is the output I get:
Could not find addressable-2.4.0 in any of the sources
Run `bundle install` to install missing gems.
I am using Ubuntu 14.04 and in order to get wpscan to work, it asked me to install Ruby 2.3.0. I did this via RVM.
wpscan.rb has a few dependencies and it seems it's not instantiating them. Also if I'm inside the wpscan folder and do ruby ./wpscan.rb ... it will work. However if I try to do this from the home directory: ruby wpscan/wpscan.rb ... it throws an error:
[ERROR] cannot load such file --typhoeus
[TIP] try to run 'gem install typhoeus' or 'gem install --user-install typhoeus'. If you still get an error, Please see README file or https://github.com/wpscanteam/wpscan
I have no knowledge of Ruby, this is my first real Python script, and I just installed wpscan 2 nights ago. I'm way out of my league here and I need help. Any further question can be elaborated per request.
Most probably, ruby in your python script is not the same as ruby in your shell. This can happen if you e.g. have a default system ruby installed (e.g. from the system packages) and you install another ruby version via RVM.
When using shell, the RVM automatically loads it's environment from the shell init scripts (e.g. ~/.bashrc) and knows which ruby to use from its settings. Whereas your python script does not load any rvm environment (it's not a login shell) and calls the default system ruby.
In that case, you need to explicitly call the correct ruby from the RVM in your python script. You can to it by calling the RVM wrapper:
browse directories under ~/.rvm/wrappers/ and find the correct ruby version and gemset that you want to use
in your python script, call the ruby command from this wrapper directory instead of the plain `ruby, something like:
rvm_ruby = os.environ['HOME'] + "/.rvm/wrappers/ruby-2.3.0-p100#myproject/ruby"
os.system(rvm_ruby + " ./wpscan.rb -u www.mysite.com")
This should fix your problem.
Thats so simple to execute ruby scripts from python...
import os
os.system('ruby filename.rb')
#if you want to store the output in seperate file
os.system('ruby filename.rb > outfilename.txt)
I have installed ruby 1.9.3, with RubyInstaller and DevKit. I installed the required gem I'm looking forward to use, but no matter what I do i can't get it working. I run my program and i get the following runtime erro:
C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/gnuplot-2.6.2/lib/gnuplot.r
b:59:in `gnuplot': gnuplot executable not found on path (RuntimeError)
from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/gnuplot-2.6.2/
lib/gnuplot.rb:74:in `open'
from cluster.rb:182:in `<main>'
What have i done wrong? I did try to add require rubygems, run :cmd>> ruby -rubygems ...(params)..., I installed the gem via gem install gem_name in the curent working directorie, but i can't make it find my gems.
PS: I encounter this problem on windows OS.
Solution addition: the path C:....\gnuplot.exe must be added to the PATH variable
The gnuplot gem is just a wrapper for the actual gnuplot application. This means that the application needs to be installed in order for the gem to work.
Your error mentions line 59 of /lib/gnuplot.rb which is an error raised when the gem attempts to find your system's installation of gnuplot. For Windows, it is looking in your PATH system variable.
If you do not have gnuplot installed prior to using the gem, you can download and install it from its SourceForge files page.
From Gnuplot's Rubyforge site:
"If the gnuplot executable for your system is called something other than simply 'gnuplot' then set the RB_GNUPLOT environment variable to the name of the executable. This must either be a full path to the gnuplot command or an executable filename that exists in your PATH environment variable."
I'm guessing the problem is that executables in Windows end with an .exe extension, so the program is looking for something just called 'gnuplot' and isn't finding it. You can try to set RB_GNUPLOT to the full path of the executable on your system. I've had to set environment variables in Windows before, it's possible; just google the solution for you particular OS.
I am trying to get RubyTest to work in Sublime Text 2. I followed the Instruction on the Github Readme and get the following error. Does anyone know how I could fix this?
/bin/sh: rspec: command not found
To get this to work you only need to change one setting in the RubyTest package in sb2.
If you are using rvm, your rspec gem is installed through rvm and is not found in /bin/sh
So you need to set the RubyTest package for Sublime Text 2 to automatically check for your rvm environment variables.
What to change:
1) In Sublime Text 2, go to Preferences|Browse Packages. This will open up your packages directory.
2) Open the 'RubyTest' directory and look for the file 'RubyTest.sublime-settings'.
3) find the line that says:
"check_for_rvm": false,
and change it to:
"check_for_rvm": true,
save the change.
4) That's it. It should now work.
Good Luck
This worked for me:
If you're using RVM, open a project with command line from the project's folder:
subl .
Then, it'll hook the ruby version and gems.
This is most likely due to using RVM. What is the output of
which rspec
on your command line?
Also of note, just because you've included rspec-rails in a Gemfile, does not mean that 'rspec' is an executable program that your system knows about.
You can edit the RubyTest.sublime.settings to refer to your particular path to the rspec executable and it should work.
Unfortunately, this has the nasty side effect of being tied to one particular version of Ruby. If you're using RVM to switch between versions, you'll have to update your sublime.settings.
One work around, is to run Sublime from the command line.
Running Sublime Text 2(2165) with RubyTest plugin. Ruby and Gems managed with rbenv (0.3.0).
First attempt to use RubyTest gave the following error:
/bin/sh: rspec: command not found
From the command line I ran
which rspec
and it returned no results.
After some digging, I read that bundle install does not put the executables in your $PATH.
Alternative executable paths not picked up by shims sometimes
In order to use the executible outside the app, I had to delete the gem installed by bundler and then install it manually.
gem uninstall rspec
gem install rspec
followed by
rbenv rehash (Note you will need to run bundle inside your app so it updates the location of the gem)
This had to be performed for each version of ruby I have under rbenv control.
Now when I run
which rspec
it is found in the path and RubyTest is able to grab it without any problems.
fwiw, I had to repeat the steps for cucumber as well. To use all of RubyTests' features, ruby, cucumber and rspec executables need to be in your $PATH (for rbenv it is ~/.rbenv/shims/).
Try change the path to usr/local/bin/
I wrote a post on Sublime Text Build Scripts which should show you how to do this.
http://wesbos.com/sublime-text-build-scripts/
Same issue for me. With rspec 1.3.2 what I just did to fix it is to edit the RubyTest.sublime.settings file in the plugin folder, changing the "ruby_rspec_exec" key from:
"ruby_rspec_exec": "rspec"
to
"ruby_rspec_exec": "spec"
It really depends on the location where you have your rspec executable file...
I had the same problem after installing RubyTest by cloning from the repo. I simply uninstalled and reinstalled the package inside Sublime using Package Control, then everything worked fine.
You can see a summary of this issue here: https://github.com/maltize/sublime-text-2-ruby-tests/issues/36
Essentially, what Jim said was correct, you're running RVM or some other ruby vm manager that similarly monkeys with your PATH. Following the directions from this issue I did the following:
Install the binaries in my project
bundle install --binstubs
Add the path to my .bashrc and source it
echo 'export PATH="./bin:$PATH"' >> ~/.bashrc
source ~/.bashrc
Open the sublime project from the command line (so that PATH is available in Sublime Text 2)
subl .
The following steps worked for me (I encountered the same error as OP):
Install the RubyTest plugin through the package control manager.
Note* If you don't have the package manager installed - I highly recommend it for managing sublime plugins - more info here.
Be sure to add the code here to your RubyTest.sublime-settings file.
This file can be found at (from the menu): Preferences -> Package settings -> RubyTest -> Settings User
Save file, close Sublime and restart Sublime from the terminal in your project's folder using (so PATH is available in Sublime): subl .
No, you don't need to change paths, run sublime from command line etc.
If you are using RVM, you only have to do this:
Go to Sublime Text 2, go to
preferances-> package settings -> RubyTests
and pick settings-user or settings-default (depending what you are using) and change line:
"run_rspec_command": "rspec {relative_path}"
to
"run_rspec_command": "bundle exec rspec {relative_path}"
And so forth - add bundle exec to all commands
I spent many hours struggling with this same problem! I could not get rspec to run within Sublime Text 2, using the Michael Hartl "Ruby on Rails Tutorial." It kept saying:
/bin/sh: rspec: command not found
I finally realized that the RubyTest package (https://github.com/maltize/sublime-text-2-ruby-tests) was looking in the WRONG PLACE for my RVM!
On my Mac, the path for RubyTest is /Library/Application Support/Sublime Text 2/Packages/Ruby Test
First, to make RubyTest seek the RVM, I changed the parameter in RubyTest.sublime-settings from
"check_for_rvm": false, to "check_for_rvm": true,
Then I dug into the Python code of run_ruby_test.py: https://github.com/maltize/sublime-text-2-ruby-tests/blob/master/run_ruby_test.py
At line 151, inside class BaseRubyTask, it had the wrong path for my RVM:
rvm_cmd = os.path.expanduser('~/.rvm/bin/rvm-auto-ruby')
I changed it to the full correct path: rvm_cmd = os.path.expanduser('/usr/local/rvm/bin/rvm-auto-ruby')
If this is not your path, find the correct path by typing
$ which rvm-auto-ruby and substitute that instead.
After saving run_ruby_test.py, I went to Terminal, cd to my Rails application directory, and ran spork
Finally, I opened static_pages_spec.rb in Sublime Text 2. Now all the tests work from it!
I'm using rbenv and found that adding the following to my .bashrc did the trick
/Users/user/.rbenv/shims/rspec
I have not found a tab-completion script for RubyGem in Bash/Zsh.
Where can you get the tab-completion script for RubyGem in Bahs/Zsh?
Executable RubyGem commands are installed into /usr/bin or /usr/local/bin or whatever prefix Ruby is found under. Tab completion for commands should just work just like any other executable file in your PATH. If it's not working, verify that the directory RubyGems installs commands into is in your PATH.
There is currently no official method of doing tab completion for the parameters to any of these commands. If you need tab completion for a command installed via RubyGems, you'll need to write and/or install it yourself. See the Bash reference manual for details. There may already be a completion system for the specific command you're interested in, so be sure to google for it, but most commands installed via RubyGems do not have any auto-complete written for them.
Try:
http://github.com/oggy/ruby-bash-completion
To install it just copy gem file to /etc/bash_completion.d/
I had errors when trying to tab:
gem install
Because I didn't have some cache files in .gem directory. So I simply disabled it by editing gem file. I changed _gem_all_names function:
function _gem_all_names {
echo ""
}
That github-hosted bash completion is now part of Ubuntu Lucid Lynx. Sweet! If you apt-get install rubygems1.8 then the completion (commands and options!) should just work.
Unfortunately, as installed, it will only complete if it sees invocation of gem1.8, and not the more conventient gem. You can fix that manually if so inclined by extending the last line of /etc/bash_completion.d/gem1.8 to include gem as part of the complete name list. I'm sure there's a cleaner way, but that works.
This is (years) late, but as I was highly unsatisfied with the various completion scripts for gem that seem to be floating around the net, I decided to write my own based (somewhat) on the rather nice git completion script available in git-sh.
