I've gone through hours of tutorials and stackoverflow articles and still haven't found a solution.
Ruby is installed and it works fine.
I ran the command gem install rails and it went through the gem installation process; I watched as my C:\ruby\lib\ruby\gems\2.4.0\gems directory was updated with rails dependencies. The funny thing is I don't actually see a gem called rails? I only see rails-dom-testing-2.0.3 and rails-html-sanitizer-1.0.3
I close the terminal and reopened and it doesn't recognize the rails command at all.
I checked that my PATH c:/ruby/bin matched the executable directory listed in the command gem environment.
Still no dice.
Anyone have any suggestions?
The problem was with msys/mingw, I didn't have them installed so rails was failing to install.

I'm trying to create my first rails app. I'm on a Macbook Pro, so macOS.
I've been following this guide setting up rbenv, rails etc.
https://www.digitalocean.com/community/tutorials/how-to-install-ruby-on-rails-with-rbenv-on-macos
Then I'm following a crash course on YouTube. In the terminal I try to create a new rails app
rails new foodlog
It starts to set up in the folder I made for it, but the following happens during setup
Bundler::PermissionError: There was an error whle trying to create
'/Users/myusername/.rbenv/versions/2.7.5/lib/ruby/gems/2.7.0/extensions/arm64-darwin-21/2.7.0/racc-1.6.0'.
It is likely that you need to grand executable permissions for all parent directories and write permissions for
/Users/myusername/.rbenv/versions/2.7.5/lib/ruby/gems/2.7.0/extensions/arm64-darwin-21/2.7.0'
This error continues repeating the same thing with things such as "strscan".
Then after it says
In gemfile:
rails was resolved to 7.0.3.1, which depends on
actionmailbox was resolved to 7.0.3.1, which depends on
net-imp was resolved to 0.2.3, which depends on
stscan

Run 'bundle install' to install missing gems.
rails turbo:install stimulus:install
Could not find gem 'sprockets-rails' in locally installed gems.

I've tried looking online, coming across similar but not exact issues. For example, one solution suggested doing bundle install in this directory, versus where the guide says do it in the home directory. So I do that and get
Bundle complete! 0 gemfile dependencies, 1 gem now installed.
Still doesn't do anything. I think the main culprit is the permissions error it mentions above? This is my first time trying to really do any development on the macOS and I'm sure there's just a misunderstanding somewhere regarding permissions, so if anyone can help that would be appreciated!

Your question does not mention, so I think you might have missed this suggestion. Make sure all directories have the executable permission
I'm following Michael Hartl's Ruby on Rails tutorial, and I got stuck at trying to start rails server on my Windows 7 machine.
I'm trying to do this by following instructions in Chapter 1.2.5., i.e. by typing
rails server
However, instead of booting WEBrick, this returns the instructions for usage of 'rails' command. I've been googling this for a while, and some of the answers seem to have implied that something is wrong with the rails gem.
Now, I've found the rails gem folder ("C:\RailsInstaller\Ruby1.9.3\lib\ruby\gems\1.9.1\gems\rails-3.2.3"), and it's empty!
Also when I try
rails -v
it returns "Rails 3.2.16", although I've removed this version of the gem; if I try
gem list
it kept telling me that the version is 3.2.3.
This persisted until I deleted railties version 3.2.16, which resulted in
rails -v
returning 'Rails 3.2.3', but I still can't boot WEBrick.
Any help would be appreciated.
Did you run the installer?
At the time of this writing, I recommend using the Ruby 2.0.0-p353.
http://dl.bintray.com/oneclick/rubyinstaller/rubyinstaller-2.0.0-p353.exe?direct
Save yourself some future gem headaches and install the DevKit too.
http://rubyinstaller.org/downloads/
It should create a folder at C:\Ruby200. Start a new command prompt for the new paths to take affect.
Once Ruby is install, gem install Rails. From your other post, I recommend gem install rails -v 3.2.16
Then execute rails new project_name, then cd project_name. Then run rake db:migrate to create the initial database. At this point, you should be able to run rails server and visit localhost:3000 in your browser.
OK, I've managed to solve my problem.
I've seen a few more people having the same issue, but none of the solutions that I've found helped me, so here's what did it for me, though I'm not 100% sure what exactly was that one thing that actually did it...
I've followed the advice #scarver2 gave in response to my other question, and uninstalled both Rails and Railties gems from my crispy fresh installation of Ruby 1.9.3. (I've installed it using RailsInstaller). Then I've installed Rails 3.2.16 gem by typing
gem install rails -v 3.2.16
and this also installed the corresponding Railties 3.2.16 gem without my intervention.
Then I followed steps from chapters 1.2.3. and 1.2.5. of the tutorial, but making sure that line referencing ruby version in my Gemfile actually corresponds to the version of Ruby that I have installed.
I typed
ruby -v
in the console, to make sure that I have version 1.9.3. indeed. Confirming this, I've edited the Gemfile in my app so it says
ruby '1.9.3'
instead of ruby '2.0.0' line that's used in Listing 1.5. of the tutorial.
After that I've simply went to my app folder, and typed
bundle update
bundle install
in the console, and this time it did not return any errors as it did in my previous attempts. After that, typing
rails server
did what it should have, and my WEBrick server booted, allowing me to access my app on localhost. Yay!
Now, what I think may have gone wrong the last time was either me screwing up the Gemfile, so the gem versions and their dependencies got messed up. I also assume that ineptly trying to fix this by installing and uninstalling different versions of various gems did not quite help. What may have helped was uninstalling Rails and Railties gems, and installing Rails gem again.
I am super, super new at programming and I have been trying to get everything set-up on my computer. I have installed RailsInstaller, go to >railsinstaller_demo, and type in rails s. I get the following error though could not find gem 'uglifier <>= 1.0.3> x86-mingw32'
I looked through the forum and found how to do a gem list and i noticed it was not there. I then went to gembundler and ran $ gem install bundler. I tried again but it did not work.
I am sure the answer is on this site, but i am so new that i see all these lines of code I actually have no idea where to type it in.. I am running Windows 7.
thanks for taking the time to help out a real beginner.
Have you gone to the $ railsinstaller_demo directory and run the bundle install command? This will install the gem dependencies for the application; you will not be able to run the server until you've bundled the gems. Additionally, if you're still having issues with the uglifier gem, go ahead and remove the line in the Gemfile and then run bundle install
If you need further help with the Command Prompt, you an find out more at http://bit.ly/ZajVeW.
Thanks,

Bit of a strange question, but here goes.
I'm a relative beginner to rails, and I've just started working on my second app locally. However, after each install I'm getting the following problem - that several gemfiles are missing (railties being the most obvious).
So, I deleted the install, re-ran it and listed the gemfiles - they are all there. However, after initializing a git repo and pushing the project up to my GitHub a gem list command shows that a number of gems are now missing - at this point I can't run any rake commands or for example rails server.
So I cleared the repo and re-installed. gem list says the gems are all present, server and rake commands work; but push the repo and it subsequently packs up - gem list shows only a handful of gems remain.
Bearing in mind my experience, I'm prepared to believe I'm missing something very obvious, but any advice would be appreciated.
welcome ;-)
I suppose you want to create a Rails 3 application. So first make sure you have installed bundler.
gem install bundler
The steps for creating the application are:
rails new your_app
Then run bundler in the applications folder:
cd your_app
bundler install
Now you should be able to run the application:
rails s
Go and visit localhost:3000. If that does not work, you have other problems. Paste the stack trace then ...
The problem was I forgot that I had two versions of Ruby installed and I had not properly set a default with rvm for some reason. Specifying the default then checking the gems were present for that version of Ruby fixed it.
Before i get into whats wrong, I have tried tutorials and looked at stackoverflow questions, including this one, so I don't think this is a duplicate answer.
I am using Aptana 3.0.4, Rails 3.14, and ruby 1.9.2.
I can start the server normally just fine through aptana or the command line. When i try to run in debug mode i get this: http://i.imgur.com/vYKuY.jpg
However, i have installed the ruby-debug-ide gem, have it listed in my gem file, and bundle installed. I have also tried using ruby-debug19 and ruby-debug-ide19 (bundle installed after trying each gem).
gem environment is the correct path to where my gems are installed. ruby-debug-ide and all the others are located in that path.
I am not sure what I am doing wrong. Please help.
