I recently decided to convert my app's database from SQLite to MySQL and apache (using xampp). I installed xampp with no issues and I followed Convert a Ruby on Rails app from sqlite to MySQL? SO to prepare my app for the switch. I then attempted rake db:migrate and instantly received this:
No Rakefile found (looking for: rakefile, Rakefile, rakefile.rb, Rakefile.rb)
I back tracked made sure the MySql gem was installed and tried another rake command, no luck. I uninstalled ruby on rails and re-installed, created a fresh app, and still no luck. In fact, as soon as I try to use any rake command after re-installing I get that error. I have checked to make sure the rakefile exists. I have no idea what is going on and I couldn't find anyone with the same issue.
the rake commands were working fine for weeks. At some point in the last 24 hours I messed it up somehow.
One other point of interest, i first installed db explorer before xammp but wasn't able to get it to run.
EDIT: Fixed issue by uninstalling rails, backing up and deleting all apps, deleting .gem folder, removing all global paths. Then re-installed with RailsInstaller, set user Paths, went to rake directory and rake command did not return the perpetrating message. I then created a new app with MySql2 and merged in my original app...
I am still no closer to understanding why rake suddenly stopped working. Therefore, I'm leaving this SO up in case I or another user discovers the cause.

I'm brand new to Rails and am following this tutorial on how to make Rails applications. I can't get the database to migrate to my heroku apps.
I'm currently at the beginning of chapter 3, trying to set up an app to use for the rest of the course.
I've been following the tutorial perfectly, and, so far, I've already built two apps and deployed them to heroku and migrated the data just fine, but the third time it's not working.
I was able to make the heroku page and push the app to it, but I just can't migrate the data.
I typed:
heroku run rake db:migrate
and got this error:
/usr/bin/env: ruby.exe: No such file or directory.
I'm assuming this means it's looking for the file in that directory and not finding it. How do I change where it's looking?
I checked "windows heroku run rake db:migrate error “/usr/bin/env: ruby.exe: No such file or directory”" and did what the answers recommended, that is, change "ruby.exe" to "ruby" in bin/bundle, bin/rails, and bin/rake, but that didn't work.
Any other tips? I have been stuck on this for hours. Thank you so much in advance.
The command is normally heroku run rake db:migrate. You should try that instead of heroku run rails db:migrate.
Make sure you've pushed your app to heroku. When it's pushing to heroku, make sure that it is also detected as a rails app. It's possible that heroku isn't detecting a rails app so the environment it sets up doesn't have ruby installed. But it may just be the error in the command name (rails instead of rake).
I had a similar problem on a repository I had ported over from windows.
It turns out that several scripts in the app's bin directory still had a shebang lines (#!/usr/bin/env ruby.exe) to ruby.exe instead of ruby. Once I fixed these scripts the problem went away.
On your local dev machine, before committing to git (and then pushing to Heroku), try changing the line endings to Unix line endings (rather than Windows line endings). On a *nix machine you'd do that by running dos2unix myfile.rb
If the line endings are wrong, the Linux loaded on Heroku will look for ruby^M and not for ruby, and will of course not find it, and give this exact error message.
I've just pushed a new Rails app from my local development machine to a server I have that has a few Rails apps already on, bundle installs everything correctly and rake tasks run fine, however when I try and start the app it fails with that message.
I've:
Trashed my Gemfile.lock and reran bundle install
Done gem install rake to get the latest version
Checked rake --version shows 10.0.4.
Checked bundle show rake shows 10.0.4
Restarted the server
Now I'm drawing a blank on what it could be. Using Phusion Passenger, rails 3.2.13, ruby 1.9.2p290. I use rvm for managing the environment, but I've not changed anything with it for a long, long while now. The other Rails apps are all working okay without any issues, with similar gem dependencies.
Self fixed, but not sure why. I ran bundle install rake by accident, forgetting it doesn't do what I think and it created a ./rake folder which solved the issue.
Perhaps your application is being run as the wrong user.
Since I am new to rails and have learned the very basics from books I now figured that I can learn quite a bit more from reading other peoples code and trying to make sense of it so I have signed up at github and set up everything there. Now I read that one good open source project to learn from is radiant so I went to https://github.com/radiant/radiant and cloned it to a local directory. THen I proceeded as follows:
cd radiant
bundle install, which went fine
rake db:migrate, which first returned:
rake aborted! You have already activated rake 0.9.2, but your Gemfile requires rake 0.8.7. Using bundle exec may sol
So I typed in bundle exec rake db:migrate and recieved the following:
NOTE: Gem.source_index is deprecated, use specification. It will be removed on or after 2011-11-01. Gem.source_index called from c:/Ruby192/lib/ruby/gems/1.9.1/gems/rails-2.3.14/lib/rails/gem_dependency Rake aborted! No such file to load -- radius
So here I am wondering how to fix this problem? I also noticed that a Gemfile and a Gemfile.lock already existed in the radiant folder when it was cloned, which perhaps could be part of the problem?
Also I wonder if it is crutial that I run the same version of rails as the project is written in?
Now it should be said that I currently have rails 3.0.5 installed and run on windows
I hope someone can help me here, it has been quite frustrating since I have not been able to run any cloned github repos (radiant here just being one example).
You should edit your Gemfile and make it require newer rake.
Also you can run rake db:migrate --trace to get additional error information.
The deprecation warning is still just a warning, and it shouldn't be causing you any issues. The part of that error that is relevant is the No such file to load -- radius. You probably need to follow the instructions for installing Radiant, which include running a gem install radiant before dropping this project code somewhere.
Bundler manages installing and using the gems in your Gemfile, and if a Gemfile.lock is present it'll use those exact versions. This means you can't run Radiant with Rails 3.0.5 since the Gemfile specifies 2.3.14. Bundler will install Rails 2.3.14 and its dependencies automatically, though, so you don't need to worry about it.
By the way, this project looks like it has been very mismanaged. It's not common for a Rails project/gem to force you to actually clone it to use it. If you want to check out a Rails 3 project to learn from, I have a slim Rails 3 app that was intended to be an API up publicly on Github with some really clean code: http://github.com/coreyward/instavibe
Ugh, I'm not sure what happened, but when I tried to run my development environment, I get this:
vendor/bundler_gems/ruby/1.8/gems/rails-2.3.8/lib/initializer.rb:271:in `require_frameworks': no such file to load -- active_record (RuntimeError)
I'm pretty sure I made pretty much no changes, I did do a rake cron, and that worked fine, but now I don't know how to debug this.
I can't do a restore with a git to the last HEAD because it says not writeable...help!
Maybe you updated your gems and didn't specify which rails version your application should use... And with the new rails version the old structure doenst run (if you only specified to take the last rails version)..
Try to install the correct rails version again..
I'm deploying a rails application using Capistrano to a shared server (on WebFaction). This means there are several different Ruby version installed there.
Everything works fine until I want to run some rake tasks. These tasks fail by saying I don't have the right RubyGems version.
From this thread I understood that fixing it would be as easy as adding the full path to the correct rake folder to my rake commands. I tried that but failed again, now because the Ruby interpreter that is used is the wrong one.
I assumed that capistrano would use the username/password I gave it to run commands on the server but it seems not to be the case.
Am I missing something? How can I fix that?
Thanks!
This is indeed a path issue. I solved it by symlinking my ruby, rake, and rails executables to my path. For instance, if the executables that you want (but are failing to work) are located at /opt/ruby/bin/ruby, you'll symlink it to:
ln -s /opt/ruby/bin/ruby /usr/local/bin/ruby
