Hello I am having trouble running the command "bundle exec rspec" in vscode. Every time I run the command I get an output of "No examples found". I have two files in a lib folder and two files inside spec folder. I have updated my bundle and have "_spec" in all my spec files. First time debugging no idea what I am doing.

In my project, I have a Gem that contains a shell script in its bin folder, let's call the script do_something.sh.
do_something.sh actually executes a ruby script using Jruby command, the script is called ruby_script.rb.
I am trying to call do_something.sh from my project using:
bundle exec do_something.sh
it keeps throwing errors for all shell commands in the script. I erased all the contents of the script and added only one line "echo 'Hello'" and it is still throwing the following error
NoMethodError: undefined method echo' for main:Object
/usr/local/rvm/gems/ruby-2.1.1#projectName/gems/gemName/bin/do_something.sh:10:in'
/usr/local/rvm/gems/ruby-2.1.1#projectName/bin/do_something.sh:23:in load'
/usr/local/rvm/gems/ruby-2.1.1#projectName/bin/do_something.sh:23:in'
Edit#1
All the files has execute permission.
I also tried to put ruby_script.rb in the bin directory where are files are executables (according to a rule in the gemspec file) and tried calling
bundle exec ruby_script.rb
I get the error "bundler: command not found: ruby_script.rb"
bundle exec ruby ruby_script.rb
I get the error "ruby: No such file or directory -- ruby_script.rb (LoadError)"
Why am I getting this error and how can I solve it? I want to be able to either run do_something.sh or ruby_script.rb. Right now, ruby_script.rb is not recognised and do_something.sh does not recognise the commands.
Ok, finally after two days, I was able to make it work.
bundle install installs my GEM and creates a ruby wrapper by default to sh files in the 'bin' directory. So, when I call my script using bundle exec the ruby wrapper gets called first and it calls my script using a ruby 'load' function. This load function expects a ruby file and that is why all my shell script in the file threw errors, because they were expected to be in ruby.
A workaround to this is installing my gem before 'bundle install' using the following command:
gem install --no-wrapper my-gem
Apparently this command disabled creating the ruby wrapper and I was finally able to call the script using bundle execute do_something.sh
Try specifying sh when you run bundle exec. The NoMethodError is from the script being executed in ruby and not sh.
bundle exec sh do_something.sh
In order to make it work. Setting_up_permissions_on_a_script
First: you have to change the mode for the file using chomd +x file_path
Second: Now you can call either by bundle exec file_path or ./file_path
N.B
1: Don't forget to add #!/bin/sh on top of the file.
2: And do check with deploy-a-shell-script-with-ruby-gem-and-install-in-bin-directory will definitely help you.
Hope this help you!
According to Rubygems Specification Reference, executables included in the gem
... must be executable Ruby files. Files that use bash or other interpreters will not work.
In order to to add an executable to a gem please make sure to read the Adding an executable section on Rubygems Guide.
Eventually you'll be able to run the executable like this:
bundle exec do_something
where bundle exec part is optional.
Without cd-ing into the root directory of my Rails application, how can I execute a Rails or Rake command for that application.
I tried:
bundle exec rake my_tasks:do_stuff BUNDLE_GEMFILE=/PATH/TO/RAILS_APP/Gemfile
among other combinations, to no avail.
[Update]
The issue is actually two-fold, bundle doesn't know where the gemfile is and rake doesn't know what to run.
To use Bundler:
BUNDLE_GEMFILE=/PATH/TO/RAILS_APP/Gemfile bundle exec ...
Note that BUNDLE_GEMFILE has to go before 'bundle exec'.
To use Rake:
rake -f /PATH/TO/RAILS_APP/Rakefile my_task:do_stuff
To use Rails console:
????
Have yet to figure out how to enter the Rails console from another directory. Looking at the source, I think it may not be possible, because it eventually does File.join('script','rails') to kick off the rails process.
Without you showing the error message you are getting, I'm assuming it has less to do with Bundler than it does Rake. When the rake command is run, it searches for a Rakefile starting in the current directory and traversing up the tree until it finds one. You can override this behavior by explicitly specifying a Rakefile in the options to the rake command. This is done using the -f <RAKEFILE> option.
eg.
bundle exec rake -f /PATH/TO/RAILS_APP/Rakefile my_task:do_stuff
Bear in mind that your Rake tasks have to be "CWD agnostic". Most tasks and scripts are as they tend to get the project directory based on a path relative to a known file in the directory tree. You probably already understand that, but it's worth mentioning in case the tasks are expecting the current working directory to actually be the rails root. That would be a case where running them from outside the project could potentially be dangerous.
I am executing a command rails new sample_app. After creating a project sample_app, I executed bundle show command but it Could not locate Gemfile.
I Google and found stackoverflow solutions 1 2 3 in which they didn't find gemfile whereas in my case i have. Suggest some solutions.
I think you should be in sample_app directory. For this run on command prompt cd sample_appthen execute bundle installthen bundle show
Hi cloned a simple app ( https://github.com/cfx/twix) on github that allows me to send Twitter messages from the console, but I'm not sure how to run it.
I now have a folder in my users/name director called Twix. Inside twix, I have these folders created by the app.
README Rakefile bin lib test
The readme doesn't provide a lot of instruction to get things started. It just tells you what to do after the program's running (see below).
Questions: What command do I use to get this started? What folder do I need to be in?
The README
Twix 0.0.1
Simple twitter client for console
Keys:
q - quit
t - write new message
If you want to post your twit, finish you message with !SEND
If you want abort and back to your feed, finish your message with !EXIT
new features soon
This program is packaged as a gem. The following command will install the gem (run it in the Twix directory):
rake package && gem install pkg/twix-0.0.1.gem
You can now run the program from anywhere with the twix command.
Edit
The first thing I saw in the repository was the Rakefile, meaning there were some rake tasks defined. When you find yourself in this case, running rake -T is your best bet as it will show you the rake tasks available. Its output was the following:
(in /home/benoit/code/clones/twix)
rake clobber_package # Remove package products
rake gem # Build the gem file twix-0.0.1.gem
rake package # Build all the packages
rake repackage # Force a rebuild of the package files
I picked the command that would be the most likely to build the gem: the package one. I guess the gem task would have worked as well.
Running rake package gave me the following output:
(in /home/benoit/code/clones/twix)
mkdir -p pkg
WARNING: no homepage specified
Successfully built RubyGem
Name: twix
Version: 0.0.1
File: twix-0.0.1.gem
mv twix-0.0.1.gem pkg/twix-0.0.1.gem
All that was left was to install the pkg/twix-0.0.1.gem created by the previous command:
gem install pkg/twix-0.0.1.gem
There's another case you could have encountered: the presence of a twix.gemspec in the root directory of the application. In this case, running:
gem build twix.gemspec
would have built the gem, the installation step remains the same.
ruby ./bin/twix
or
ruby -I lib ./bin/twix
I'm trying to get started with RSpec. I already had Ruby 1.8.7 installed on my Windows 7 machine.
So I typed gem install rspec and that seemed to work. But if I type spec in the command line, the command is not found. My path currently includes the bin folder in my RUBY_HOME.
If I look into the C:\Users\Eric\.gem\specs\rubygems.org%80\quick\Marshal.4.8 directory, I do see four RSpec files such as rspec-core-2.5.0.gemspec. Nevertheless, the spec command fails even in this directory.
What needs to be done to install RSpec correctly? It would seem like a path issue, but I have been unable to find a directory where the spec command works, so I can't figure what to add to my path.
On Windows, try this bundle exec rspec spec
There's no spec command in RSpec 2. Try rake spec or rspec spec.
