ruby bin\rails server not working

Hi,

I have rails 5 and using the command "ruby bin\rails server" to run rails server as mentioned in the video. But I get the following error :

C:\RailsInstaller\Ruby2.2.0\bin\ruby.exe: No such file or directory -- binrails (LoadError)

Any inputs on what's wrong. I have Windows and have used Railsinstaller to install ruby and rails

Hi! Are you trying to run the command inside the rails project folder?

Ok, let's see:

First of all the command that you're running (if it's ruby bin/rails server) is wrong, the correct command you should be running is bin/rails server (I saw that you're working on windows so you can Ignore this).
Secondly this command have to be run inside the rails project directory (but you already told me that you are inside).

Maybe the problem is the command that are you trying to run is not the correct, but, the error says that you're not inside a rails project folder, so that's weird.

Try creating a new rails project typing:

rails new new_project

Go to your project folder:

cd new_project

After that try again:

bin/rails server (in your case ruby bin/rails server)

@Ethan Rivas bin/rails server worked this time. I was using ruby bin\rails because it was mentioned in the video.

Thanks a lot for your help :)

Purvi Agrawal No problem! Happy coding!

September 7, 2016 5:47pm

Purvi Agrawal , I suspect the difference is that you originally installed using Rails Installer, and you're still launching a command prompt/terminal that came with Rails Installer. It seems likely that commands will work differently there.

First:

Change into your Rails app directory.

Then, I would try the following things, in order. Some of them will probably fail. Continue using the first one that works:

Run bundle exec rails server
Run rails server
Run ruby bin/rails server (Note that's a forward slash, not a backslash.)
Run bin/rails server

I would appreciate it if you would reply here and let me know which one, if any, works for you. Even better would be if you copy and paste the commands and their output, including the ones that failed and the one that eventually works.

August 26, 2016 4:32pm

Ethan Rivas Yes. I changed the directory to my rails app and then run the command. Should I do it outside the rails project folder ?

August 26, 2016 4:46pm

Purvi Agrawal Yes, you have to be inside your project folder before you run the command, do you have the same error if you run this command: rails s ?

August 26, 2016 5:30pm

No. rails s works perfectly fine for me. Its just the ruby bin\rails server giving an issue.

August 26, 2016 5:33pm

Purvi Agrawal Can you run this command bundle install --binstubs and after that try again?

August 26, 2016 5:39pm

I did. And then I ran the command again. This is the error I got :

$ ruby bin\rails server C:\RailsInstaller\Ruby2.2.0\bin\ruby.exe: No such file or directory -- binrails (LoadError)

August 26, 2016 5:47pm

Purvi Agrawal What about rake rails:update:bin?

August 26, 2016 5:52pm

@Ethan Rivas Is rake supported in rails 5 and higher ? I think its deprecated !

August 26, 2016 5:56pm

Yes, it's deprecated, sorry, now is bin/rails or simple rails Edit: but I think that you can still using kt because I just try It in a New project with Rails 5

August 26, 2016 6:01pm

@Ethan Rivas Can you please tell me y did u ask me to install binstubs ?

August 26, 2016 6:05pm

Well, that helps me when I used to have that issue in my Rails project the last week.

August 26, 2016 6:07pm

@Ethan Rivas Ok. But I am just trying to understand the significance of that command. Any idea what it helps with ?

August 26, 2016 6:08pm

@Ethan Rivas Also is it possible to revert the changes it made ?

August 26, 2016 6:15pm

Yes, this command is gonna generate files in your bin folder, those come from your gems, if you're using a workflow like git you can simple go back in "time"

August 26, 2016 6:17pm

@Ethan Rivas Cool. Thanks !

August 26, 2016 6:19pm

Np :), Now, going back to your first question, something fix it?

August 26, 2016 6:20pm

@Ethan Rivas Nope. I tried the commands. Getting the same error.

August 27, 2016 3:52pm

Purvi Agrawal , out of curiosity, what version of Windows are you running?

By the way, at the time of this reply, Rails Installer came with Rails 4.2, not Rails 5. So while it should work on Build a TODO List Application With Rails 4, things won't match up exactly with Rails 5 Basics. Just something to be aware of.

September 7, 2016 11:44am

Jay McGavren Hi Jay,

I am using Rails 5. I updated my rails version using bundle install after modifying the Gem File. But I am still facing the same issue.

September 7, 2016 6:06pm

Hi Jay,

I am using the git bash command prompt. I installed it separately. I am in my rails app directory and interestingly all the above mentioned command works !

September 7, 2016 6:20pm

Purvi Agrawal , ah, that's an important detail! The ruby bin\rails command is actually meant for use in an ordinary Windows command prompt. Because you're running in Bash, you will generally want to use the commands meant for Mac or Linux users (who will also be running Bash), NOT commands meant for Windows users.

I think you'll be better off with your current setup in the long term. But that's something you'll need to keep in mind.

September 7, 2016 6:28pm

Jay McGavren Thanks a lot Jay for taking out time and making me aware of the silly mistake I was doing ! A lesson learnt well for the future :)

Eylon Cohen try deleting the folder where you installed the DevKit (running rmdir C:\RubyDevKit /s in a Command Prompt window will probably do it) before trying to install again.

November 19, 2017 5:30pm

Hello, I get something different - "Could not find gem 'sqlite3 X86-mingw32' in any of the gem sources listed in your Gemfile Run 'bundle install' to install missing gems."

I looked for this specific gem and installed it, and got a message telling me about the missing gem 'puma (~> 3.) x86 mingw 32.

bundle install does not deliver an error message but does not help as well. bundle exec rails server gives the same "Could not find gem" error message.

what am i missing?

I am working on windows and swiching 'bin/' with 'ruby bin\'

thank you :)

November 19, 2017 9:57pm

Hi Eylon Cohen , did you install Ruby and Rails following the directions here? If not, I would recommend uninstalling Ruby and reinstalling following those directions.

November 20, 2017 3:35pm

Yes. I uninstall, redownload and reinstalled.. But I made it worse... now I cant install rails. I get this message:

Jay McGavren , got back to the original problem:

Could not find gem 'sqlite3 x86-mingw32' in any of the gem sources listed in your Gemfile. Run bundle install to install missing gems.

bundle install would give me:
