I installed Aptana, and i want to try Coffeescript. When I try to "Compile and display JS" it won´t work - console shows:
....xyz.sh: line 3: coffee: command not found
....xyz.sh: line 3: pre: command not found
I don´t get it - how do i get it to run?
Thank you!
Edit:
Since yesterday I managed to get compass/sass running in Aptana (yeah!) - so i realized that my question might be wrong: Do i have to tell Aptana (Windows?) where to find the compiler?
Edit 2:
Realized: The problem is - how can this gem be installed (in Aptana if possible):
via https://github.com/netzpirat/guard-coffeescript
I get an error when installing the guard gem:
ERROR: Error installing guard:
The 'ffi' native gem requires installed build tools.
After trying some stuff here is a litte tutorial to setup compass and coffeescript for a project in Aptana:
(Info: I know very little about coding or ruby, so please be patient :) )
Create project ( i choose basic web template)
Terminal:
$ gem install compass
$ compass create myProject --using blueprint
check:
http://compass-style.org/reference/blueprint/
You also have to setup some other stuff:
I found this page and followed it through..
https://github.com/netzpirat/guard-coffeescript
Install bundle:
$ gem install bundle
$ bundle init //to create the gemfile
Install guard:
You need to install Ruby Devkit before - check this links:
http://rubyinstaller.org/downloads/
https://github.com/oneclick/rubyinstaller/wiki/Development-Kit
If you did so
$ gem install guard
$ gem install guard-coffeescript
I also installed a JS-Engine as recommended here:
https://github.com/netzpirat/guard-coffeescript#javascript-runtimes
$ gem install therubyrhino
For Coffeescript:
$ gem install coffee-script
$ gem install coffee-script-source
Then you have to edit the gemfile, mine looked like this:
# A sample Gemfile
source "https://rubygems.org"
# gem "rails"
group :development do
gem 'guard'
end
group :development do
gem 'guard-coffeescript'
end
group :development do
gem 'therubyrhino'
end
run bundle
$ bundle
create guardfile
$ guard init
edit the guardfile
# A sample Guardfile
# More info at https://github.com/guard/guard#readme
guard 'coffeescript', :input => 'myProject/coffeescript', :output => 'myProject/javascript'
you can start the guard with
$ guard start
This worked for me! If you see any mistakes please let me know!

I just installed Ruby and Middleman for the first time and I cannot get past the very first "$ middleman init my_new_project" step. I have tried Googling for solution to my problem but unfortunately I couldn't find anything that looks like the error I'm encountering.
I hope someone can help me out.
OS: Windows 10 |
Ruby: 2.2.3 (x64) (tried Ruby 2.1.7 first) |
Middleman: 4.0.0
This is the error message I'm getting when I try to create a new project in a folder I created to try out Middleman:
run git clone --depth 1 git://github.com/middleman/middleman-templates-default.git C:/Users/Lenovo/AppData/Local/Temp/d20160120-1612-c2sqbk from "."
exist new_project_test
run bundle install from ".new_project_test"
Could not locate Gemfile or .bundle/ directory
This just creates an empty "new_project_test" folder.
Screenshot of the command prompt: middleman init not working (alt. image link)
What happens if you just run 'middleman init'?
You can also try to create the Gemfile manually, if it's not getting created on the first step, then run init again. The default one would look like this:
# If you do not have OpenSSL installed, update
# the following line to use "http://" instead
source 'https://rubygems.org'
gem "middleman", "~>3.4.1"
# Live-reloading plugin
gem "middleman-livereload", "~> 3.3.0"
# For faster file watcher updates on Windows:
gem "wdm", "~> 0.1.0", :platforms => [:mswin, :mingw]
# Windows does not come with time zone data
gem "tzinfo-data", platforms: [:mswin, :mingw, :jruby]
awesome_print looks like a pretty nice gem, so I wanted to try it out.
I went to one of my projects and did:
gem install awesome_print
and it says one gem installed, documentation installed, etc.
Then, while I am in that project, I went to my Rails console to try it out, but when I did a require "awesome_print" as their help file says, I get a "cannot load such file".
Has anyone got this to work?
gem install will put the gem code on your computer, but unless the gem's source code files are on your load path, require won't be able to find them. bundle exec looks at the nearest Gemfile.lock and adds the source code for all the gems listed there to your load path. Rails initialization includes getting Bundler to do this for you.
One solution is to add awesome_print to your Gemfile. However, this will cause your application to have awesome_print as a dependency. Alternatively you can manually add the awesome_print library to your load path after starting up the Rails console and then requiring it:
$ rails c
> $LOAD_PATH << path/to/awesome_print-x.x.x/lib
> require 'awesome_print'
> ap {foo: {bar: {baz: :qux}}}
If you're using RVM, the path is likely to be something like:
~/.rvm/rubies/ruby-x.x.x-pxxx#your_gemset_name/gems/awesome_print-x.x.x/lib
Add it to your Gemfile like this:
gem 'awesome_print', :require => 'ap'
I add it to the development group, since that's the only time I need it. The gem doesn't have any other gem dependencies, so I routinely add it to my Gemfile.
Also, add these two lines to your ~/.irbrc file to set ap to be your default pager:
require "awesome_print"
AwesomePrint.irb!
Note that if you use this, however, any projects where awesome_print is not installed in its Gemfile will raise this error when you run rails c:
cannot load such file -- awesome_print
Depending on whatever else you may have in your ~/.irbrc file, this can cause other side effects, such as messing up your prompt. To avoid these, simply add the two lines to the very end of that file.
install it :
$ gem install awesome_print
include it in you GemFile, if you want :
gem 'awesome_print', :require => 'ap'
add this line to the file ~/.irbrc :
require 'awesome_print'
AwesomePrint.irb!
restart your shell!
just a note: I did this and it didnt work right away, probably need to restart the computer... or I just needed to close all shell tabs and open the terminal again!
Install the gem on your machine
gem install awesome_print
Get the path to which it has installed
gem which awesome_print
Add the following configuration to your ~/.irbrc and ~/.pryrc. This will load Awesome Print whenever you fire an IRB or a pry session.
*Remember $LOAD_PATH will hold whatever you got from typing gem which awesome_print
# ~/.irbc and ~/.pryrc
$LOAD_PATH << "~/.asdf/installs/ruby/2.6.3/lib/ruby/gems/2.6.0/gems/awesome_print-1.8.0/lib/"
require "awesome_print"
AwesomePrint.irb!
If you are looking to install it without having it in your Gemfile, this is how to do it:
$ gem install awesome_print
I was running into an issue where it was installing successfully but it not in the right directory.
In that case just put this in your .bashrc, this will set the load path:
export PATH="/home/user/.gem/ruby/2.3.0/bin:$PATH"
PATH="`ruby -e 'puts Gem.user_dir'`/bin:$PATH"
replace 2.3.0 with the version of ruby you are working with.
replace user with your username or if you are using vagrant then replace with vagrant
reload your .bashrc or exit the Terminal to reload changes, then install the gem again.
In my case, I struggled with PATHs and such, while missing something obvious!
# which ruby

There is probably something I could have told brew to do to fix things, but I was impatient. :-)
I just installed Ruby 1.9.3 on Windows 7 and I also installed rubygems. I'm trying to work with rspec so I ran:
gem install rspec
It seemed to work well and everything installed. SO I went on to try the example on this page. But anytime I run the rspec command I get this error message:
"Could not locate Gemfile".
According to the example, I should get: "./bowling_spec.rb:4:
uninitialized constant Bowling"
I've googled it and it was suggested I try bundle exec rspec but it still yielded the same results.
I have also tried the suggestion on this page but it yields the same results. What am I doing wrong? Thanks
Create the Gemfile with this content. Gemfile can have no extension or .gem extension
source 'https://rubygems.org'
gem 'rspec'
so you have
app/
Gemfile or Gemfile.gem
spec/
bowling_spec.rb
Also you might need to execute this commands after
gem install bundler
and then, in the app directory
bundle install
gem install rspec in the same directory as your app and
change require statement to require './bowling.rb'
I'm sure this question is an easy one for Ruby users. However for me this is a issue I can't figure out by myself.
My goal is to use a script included in the Puppet archive (ext/nagios/check_puppet.rb) on a Ubuntu-10.4 system.
I try to launch the script:
$ sudo ./check_puppet.rb
./check_puppet.rb:4:in `require': no such file to load -- sys/proctable (LoadError)
from ./check_puppet.rb:4
Ok so there's something missing. I fount out I need some library called sys-proctable available at http://raa.ruby-lang.org/project/sys-proctable/
wget http://rubyforge.org/frs/download.php/65609/sys-proctable-0.9.0-x86-linux.gem
[...]
sudo apt-get install rubygems
[...]
$ sudo gem install sys-proctable-0.9.0-x86-linux.gem
Successfully installed sys-proctable-0.9.0-x86-linux
1 gem installed
Installing ri documentation for sys-proctable-0.9.0-x86-linux...
Installing RDoc documentation for sys-proctable-0.9.0-x86-linux...
Everything looks pretty good so far! Time to launch the script again
$ sudo ./check_puppet.rb
./check_puppet.rb:4:in `require': no such file to load -- sys/proctable (LoadError)
from ./check_puppet.rb:4
the gem listoutput tells me this:
$ gem list
*** LOCAL GEMS ***
sys-proctable (0.9.0)
Where has this gem been installed?
Why can't the script load the sys-proctable lib?
What the %&$# am I doing wrong?
Where's the official doc of gem?
The gem is installed - but in Ruby 1.8 you need to have the line:
require 'rubygems'
To use rubygems. This changes the 'require' function so it will pull in rubygems when you ask it to.
So in the script:
https://github.com/puppetlabs/puppet/blob/master/ext/nagios/check_puppet.rb
Just add the require near the top and try again.
For instructions on other ways to use rubygems, consult the Rubygems documentation:
http://docs.rubygems.org/read/chapter/3#page70
this is what i am getting on centos 6.4
sudo ./check_puppet.rb
./check_puppet.rb:75:in `-': no implicit conversion to float from nil (TypeError)
from ./check_puppet.rb:75:in `check_state'
from ./check_puppet.rb:122
i added require 'rubygems'
and installed sys-proctable
I'm running ruby 1.9.2 on Windows and am trying to port code that worked in Ruby 1.8. The code uses Open4.popen4 which previously worked fine. With 1.9.2 I have done the following:
Installed POpen4 via gem install POpen4
Required POpen4 via require 'popen4'
Attempted to use POpen4 like:
Open4.popen4("cmd") {|io_in,io_out,io_er| ... }
When I do, I get the error:
no such file to load -- win32/open3
If I try and install win32-open3 (gem install win32-open3) I get the error:
win32-open3 requires Ruby version < 1.9.0
Does anyone know how I get around this problem?
Haven't used it, but this might work: https://github.com/matschaffer/win32-open3-19
Adding
gem "win32-open3-19", :platforms => :mingw, :git => "github.com/matschaffer/win32-open3-19.git"
to my Gemfile didn't exactly work.
Here are the steps that solved this for me:
Add this to the Gemfile -> gem 'win32-open3-19', :platforms => :mingw
Run bundle to install win32-open3-19
That was it. For me the git location was unncessary and didn't work.
