I am attempting to use Instiki to create a physics wiki.
Unfortunately, I know next to nothing about Ruby and Ruby on Rails, but I nonetheless brazenly followed the instructions given by the Instiki creator for running it on Dreamhost. After following the instructions (which seemed to go through fine), when I access the site url, there is a page that informs be that "Ruby on rails application could not be started", and apparently the following error is occurring:
Bundler couldn't find some gems.Did you run bundle install?
You can see this for yourself by visiting Wigner.
I have, in fact, run bundle install. I actually contacted the creator who suggested that not all required gems have been installed, but I feel relatively confident that they have been since when I executed bundle install, I saw the required gems install.
Has anyone happened to successfully install Instiki using a hosting provider (Dreamhost or otherwise)?
Any guidance/links to documentation etc. would be greatly appreciated.

So I wish I had known far before that installing Rails with sudo was a bad thing. In fact, after doing my research, it appears that most people would agree that installing any type of package manager as sudo is a big no-no.
Unfortunately for me, I found this out a bit too late. I have several Rails applications that I have created and I am worried that If I try to reinstall Rails with RVM that my applications will not work because of dependency issues.
When I would install gems with bundle install, if the gem was new, Rails would ask for my password before installing it. I did not think much of it at the time, but now, I am worried nothing will work after I try booting a Rails app.
So my questions are:
If I installed Rails with sudo, will my applications still work if I reinstalled it under RVM?
If they don't work, what would I need to make them function correctly?
How do I remove a Rails installation that was installed with sudo?
Is this issue as severe as I think it is?
I had seen a lot of related posts about why one should not use sudo to install gems and Rails in general, as well as why not to do it with RVM, and pretty much not to do it all with anything Ruby related. But I have not seen a post that really addresses any of my concerns and questions that I mentioned above.
No it's not severe as you think. Applications are meant to be portable (somewhat), once you have the same dependencies installed as your development machine, they are meant to work again otherwise you wouldn't be able to deploy.
Now the main thing to check is that all your files in your rails applications are owned by user and not by sudo (otherwise you won't be able to read them later on).
Aside from it, you can simply install rvm, ensure with which ruby and which gem comes from rvm and not from your packaged ruby installation (which you can remove, I do this usually) and then simply run bundle install in your rails application, at that point they are ready to start again.
I've been following Daniel Kehoe's book Learn Ruby on Rails and it is amazing.
I wanted to give the finished official app a test drive before continuing to better understand where I'm heading to, however I'm not sure how to do this (given the fact that I'm just beginning the book).
I forked the "learn-rails" repo from the RailsApps GitHub account and cloned it into my Mac with the name "learn-rails-guide" (as "learn-rails" was already taken for following along). When tried to start the server, I got an error saying that I should run 'bundle install'.
I did so, hoping that the gemset created during the following along won't get messed up; however 'bundle' wasn't able to install the 'pg' gem. And I hit a road block...
Is this problem related to changing the name of the app?
Does this have something to do with the finished app being set up for production?
Am I taking the wrong approach for trying the finished app locally?
Will an app with a .ruby-gemset and a .ruby-version files mess up my current gemsets if a run bundle install?
Thanks!
Use $ bundle install --without production (see the book's deploy chapter). Otherwise, you'll need to install PostgreSQL locally (which can be difficult). The repo version of the app is the final version that includes gems for deploying to Heroku.
There will be no problem with changing the name of the folder that contains the app.
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.
As an example, I want to download: https://github.com/banker/newsmonger and tinker with it (to learn Rails). I've downloaded the zip and when I go into that folder and type rails server, the terminal window says to create a new rails app
This is a Rails 2 application, and so as ennuikiller said, you'll need to run script/server.
You may run into problems with dependencies not being installed in this application, which is a problem that normally (now) would be solved with Bundler. Due to this being a Rails 2 application, it doesn't support Bundler out of the box and the owner of the repo hasn't updated it to support that, and so you're dead outta luck there.
What you'll need to do is attempt to run rake gems:install (which may or may not work, depending on the sun's positioning) which will install the gems specified in config/environment.rb and the proper config/environments files using the config.gem methodology. This was how it was done in Rails 2, and caused so many problems that Bundler was created.
If that doesn't work, contact that banker guy on GitHub and ask him what the deps are or work out the dependencies yourself.
Good luck!
Depending on the version of rails this app uses you may have to execute the following :
script/server
I am trying to build Noosfero (http://noosfero.org/), a project done in Ruby, but I am pretty new in Ruby and Linux (my current environment).
I am following the instructions in their tutorial (http://gitorious.org/noosfero/noosfero/blobs/master/INSTALL and http://gitorious.org/noosfero/noosfero/blobs/master/HACKING).
I was supposed to run an apt-get install with many packages, everything worked except for libgettext-ruby-data, to which I get a message that "E: Package libgettext-ruby-data has no installation candidate".
I then download the source and try to run "rake db:schema:load", which I get the following error:
"rake aborted!
uninitialized constant Dependencies
/home/user/noosfero/Rakefile:10"
My rake file is the following:
require(File.join(File.dirname(FILE), 'config', 'boot'))
require 'rake'
require 'rake/testtask'
require 'rake/rdoctask'
require 'tasks/rails' #this is the line that the dependency can't be found
I searched around and found this question here: Uninitialized constant ActiveSupport::Dependencies::Mutex (NameError) , but changing the config files didn't help and I could wasn't able to downgrade my RubyGems because I do not know how to do that (gem -update returns a message that I have to do that using apt-get, but I can't find out in which package the gem program is).
The first time I run Rake, I get a message saying:
"I: Installing Debian-installed Rails from /usr/share/rails into vendor/rails.
I: Please note that the recommended Rails version is 2.1.0, and that other versions might not work"
But I don't know how to downgrade my Rails version.
I've got many paths to follow, so I've got many questions, I hope you can help me:
1- Does anyone knows how to fix it directly?
2- How can I downgrade Gems?
3- How can I downgrade Rails?
4- Where can I download gems and how can I install it? (The documentation provides a link, but this link is VERY strange: http://www.yotabanana.com/hiki/ruby-gettext.html?ruby-gettext ).
Any help is very appreciated.
Thanks,
Oscar
Edit: can this error be a problem in the project I downloaded and not in my environment? After some research I am starting to think it is, can it be?
It would help if you share your rake version, by the way.
In the meantime, take a look at this:
https://github.com/jimweirich/rake/issues/33
(Only valid for rake 0.9.0, though).
This was a version conflict I had with the project I was trying to build, not it is solved :)
First of all, I'm a Noosfero developer and I need to admit that the process of preparing the environment to run Noosfero right now is pretty nasty (unless you only want to run it in the production mode since we've got a debian package). But this problem is close to an end since we're a building a vagrant box (for more info see http://vagrantup.com/) to noosfero. Things are going to be much better. But regardless all this nastiness and not having the box yet, Noosfero was supposed to run if you followed all the steps in the INSTALL instructions. Let me try to help you.
Are you using Rails 2.1.0? The best way to do so is to uninstall rails from your system (if you installed through apt-get) and install through rubygems:
gem install rails -v=2.1.0
To avoid problems ensure that there isn't any other version of rails installed through rubygems (gem list).
If you still having problems to run the schema load, run it with --trace and post it here.
If you have other problems you can try contacting us through noosfero-dev#listas.softwarelivre.org or the irc #noosfero at FreeNode.
