I'm new to Ruby and following the course Ruby on Rails Intro on course era and on the very first chapter installing software on Windows. After installing all the required software when the instructor asks me to run 'ruby new test_install' get the following exception:
Fetching source index from https://rubygems.org/
Could not verify the SSL certificate for
https://rubygems.org/quick/Marshal.4.8/sqlite3-0.0.0.gemspec.rz.
There is a chance you are experiencing a man-in-the-middle attack, but most
likely your system doesn't have the CA certificates needed for verification. For
information about OpenSSL certificates, see "bit.ly/ruby-ssl". To connect
without using SSL, edit your Gemfile sources and change 'https' to 'http'.
I should mention that I tried with gem -a sources http://rubygems.org but to no avail and I initially installed the rails 4.2.3 by giving it --source http://rubygems.org however nothing seems to work for this particular instance of command.
So far there's no fix for this that I can find. It's not limited to Win10, either. I've come across Win7 users with the same issue, so it seems to be a Rail on Windows problem.
There are also lots of Gemfiles. It's not clear which one(s) need(s) to be changed. I've tried changing couple of them with no luck.
It does look like using Linux instead of Windows is the quickest way to a solution. It might be worth giving that a try. Other than the Mac-like weirdness of the Unity interface, Ubuntu is easy to get used to and VMWare Player is free. I wouldn't bother with Virtual Box, the versions I've tried, including the latest, have been flaky.
If you do decide to try Ubuntu, you can find instructions here: https://gorails.com/setup/ubuntu/16.04
That page recommends using MySQL or Postgres. If you do use something other than SQLite (probably a good idea, in which case Postgres is probably the better option), the creation of a new rails app requires setting the database at creation:
rails new myapp --database=postgresql
for instance.
I solved the same problem with this line:
gem install bundler

I solved the problem like this:
gem source -r https://rubygems.org/
gem source -a http://rubygems.org/
gem update

I'm trying to initialize a new rails app on windows, and running rails new <appname> generates everything up to vendor/assets/stylesheets/.keep, but when bundle install is run, rails generates this error:
Checksum of /versions does not match the checksum provided by server! Something is wrong.
I'm not sure what's causing this, as I've done nothing to rails itself. Any help is appreciated.
Edit: If it's an error caused by windows being finicky, I have the option of moving to Linux, but I'd like to know what's wrong first.
I had the same issue using windows, and was able to solve it by uninstalling bundler and installing an older version.
rails new <appname>
gem uninstall bundler
gem install bundler -v 1.9
cd <appname>
bundle install
That did it for me!
In my case there was a *.pre.1 version and I chose to uninstall that particular version and then "bundle install" worked.
Try removing your ruby cache folder and then try again. So for example if you are on Linux machine and you are using rbenv and say ruby 2.1.5 folder. Your path would be similar to something like (Not sure where on windows ruby is stored):
~/.rbenv/versions/2.1.5/lib/ruby/gems/2.1.0/cache/
Removing this folder and trying bundle install again should resolve the issue.
It will be great, if you move to a Linux machine.
On windows it's a hell to pay in my 5 years of experience what i have learned is not to mess with (ror) or (rs) in windows. here's a cheeky thing you can do an easy way. I believe you are using github as repo, as a editor you are using sublime if thats is a case open your gemfile you will see check the image or
try to clear cache on your server or update the gems.
I had this same exact error and solved it the following way. I think you are missing the ruby DevKit being installed.
Go here http://rubyinstaller.org/downloads/ and download/install the latest 32-bit Ruby version (as of writing this 2.2.4, you will need it for the web-console gem)
Make sure to add your ruby\bin folder to your environmental path variable
The trick is hidden near the bottom-left of the same page under the "Development Kit" section. You need to download and extract the right one into a permanent location (as of writing this for 32-bit - DevKit-mingw64-32-4.7.2-20130224-1151-sfx.exe)
After extracting the files, go into the main directory and run "ruby dk.rb init" followed by "ruby dk.rb install" (More information can be found here
That fixed it for me and i can now fully install with no checksum issues
This problem began when i tried to run my app. I wrote rails s and the console said me Could not find sdoc-0.4.1 in any of the sources Run bundle install to install missing gems. Then i wrote bundle install and the message that appeared was Checksum of /versions does not match the checksum provided by server! Something is wrong.
I solve this problem following this steps:
Wrote bundle install
The console said me Could not find sdoc-0.4.1 in any of the sources
Then i reinstalled this gem with gem install sdoc -v 0.4.1
I tried again to write rails s and it's was solved.

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 spent several hours over the past few days trying to get PostgreSQL to play nice with RoR on my Mac.
I've followed several tutorials using several different methods such as installing PostgreSQL manually and installing from various 1-click installers
However the all the different methods I tried failed on the last step of installing the pg gem. Very frustrating!
Does anyone here have a tried and tested tutorial for getting this done? (Or would you like to write some instructions here...?)
My environment is this: Macbook running OSX 10.6, PostgreSQL 8.4.1 server
I think I've managed to find a way that works. I'm borrowing heavily from this great post1, but since they are installing a bunch of other stuff at the same time I'm going to write out what I did here for people who are just looking for the PostgreSQL install answer.
1 Editor's note: Link seemed dead when I tried. Is this the one? http://blog.blackwhale.at/?p=175#PostgreSQL Please fix if it is.
Download PostgreSQL for Mac and download the ‘Postgres.app’ installer.
Create a user for your rails development (keep in mind that if you're sharing an application during development you'll probably want the same user between all members your dev team in order to avoid headaches)
sudo -u postgres /Library/PostgreSQL8/bin/createuser
Enter your Mac OS X system user name as role name, and make it a superuser.
Install the pg gem so Rails can talk to PostgreSQL
sudo env PATH=/Library/PostgreSQL8/bin:$PATH gem install pg
Configure your rails app to talk to PostgreSQL. You can either create a new application with:
rails *appname* -d postgresql (for Rails 3 -> rails new *appname* -d postgresql)
Or for an existing app, modify your database.yml file.
This worked for me without any hiccups. If anyone else tries using this method I'd be interested to hear some feedback on how it went for you.
On a 64-bit Mac (Snow Leopard with Core 2 Duo or newer) I had to compile PostgreSQL from source, as rails kept complaining that:
*** Your PostgreSQL installation doesn't seem to have an architecture in common
with the running ruby interpreter (["ppc", "i386", "x86_64"] vs. [])
The architecture mismatch was probably bc I'd compiled rails from source, which defaulted to 64-bit. The binary installer on postgresql.org seemed only a 32-bit version. Setting ARCHFLAGS didn't fix this for me.
Anyhow, if you download the [source][1] from postgresql.org and follow the instructions in the INSTALL file, it's fairly straightforward. You don't have to create a new user if you use your own account. I did have to create the sysctl.conf file to expand shared memory - just google 'postgresql os x sysctl.conf'
Old question, but still maybe i can help someone with this (rather simple) solution:
gem install pg -- --with-opt-include=/opt/local/include/postgresql84/ --with-opt-lib=/opt/local/lib/postgresql84/
Download and Install MacPorts
fire up terminal
sudo port install ruby postgresql83-server rb-postgres rb-gems rb-rails
Thanks to Ganesh for the good awnser, my sudo url looked a bit diffirent :) here is what I havesudo -u postgres /Library/PostgreSQL/9.2/bin/createuser
Ryan Bate's Railscast on PostgreSQL walks you through setting it up on a Mac with Homebrew. Very easy, worked for me on OSX 10.6.8.
I really need help with Rubygems (that's the package manager for ruby). Since I'm behind a proxy, I've given up all hope of it working automatically, so I had to download a lot of packages manually and install them for rails to install. Now, I'm getting an error message:
Rails requires RubyGems >= 1.3.2 (...)
Once again, I manually downloaded rubygems-1.3.2.gem and installed it, however, it still doesn't work and gem -v shows 1.3.1. Help. Also, I can assure it that unless gem has HTTP1.1 Auth Proxy support, there is no way it by itself will be able to contact its server...
Before running rubygems commands, you should try something like (for windows)
set http_proxy=user:password#ip:port
Or export for linux, I guess.
It seems that one can simply download the source tarballs, untar them and use setup.rb to install the update. More information on it here.
I did this and was very pleased with the result (no problem!).
I'm used to the One-Click install local environments of MAMP. Is there a Ruby equivalent... a download that you run and instantly get the most current versions of Ruby, Rails, SQLite running locally?
I'm using a Mac, running Leopard, and am aware that all of the aforementioned technologies ship with Leopard (except maybe SQLite). The books that I have reference newer versions and the last thing I need is to try to retrofit a tutorial to work with my version.
And one more less important question: What are "Gems" and is that something that I need to make sure is fully updated too?
Installation is pretty confusing when you first start with Rails! Even though a lot of what you need is already installed if you are using Mac, personally I found it really hard to find come concise information on how to best go about setting things up.
Since I didn't want anyone else to go through the headaches that I had when configuring their Mac development environment, I've written a 7 step guide to installing Ruby on Rails, MySQL, Apache with PHP, and phpMyAdmin on OSX Leopard. In short, everything you should need to get developing locally on your Mac!
Here's the link:
http://waavoo.com/2009/7-step-guide-installing-ruby-on-rails-mysql-apache-php-phpmyadmin-intel-mac-os-x-leopard/
Hope that helps!
Take a look at FiveRuns Install. It's a free Ruby on Rails stack that you can download.
RubyGems is the Ruby standard for publishing and managing third party libraries. Check out the User Guide.
Have fun!
I have no idea what mac os are you in but Leopard (10.5.x) already have ruby installed, all you need is to updated the gems using
gem update rails
in your command line.
if you're on Tiger (10.4.x) the installation is broken, and please follow this link.
You should also have a look at Phusion Passenger - this, along with the prefpane, allows you to have apache VirtualHosts set up the easy way.
Current versions of Rails are designed to work (for development) without needing an AMP -style stack, by using SQLite and a small Ruby Web server, so if you will only be doing Rails development you don't need to set up a stack - you can just type "rails" and it will work.
BUT the versions of RubyGems and Rails shipped with Leopard are now outdated, though, so you'll need to upgrade these before you go too far. There's an article that I wrote on setting up a Mac for development here, but the minimum commands go like this:
sudo gem install rubygems-update
sudo update_rubygems
sudo update_rubygems (yep, twice)
sudo gem update --system
These get RubyGems up to the current release, so that you can upgrade Rails safely. To do that, type:
gem update rails
The last command doesn't have sudo, because if you omit it, current versions of RubyGems will install a clean copy of the gems into your home directory, leaving the system versions untouched.
Finally, amend the .profile file in your home directory, so that the line with PATH in it says:
export PATH=$HOME/.gem/ruby/1.8/bin:$PATH
Close up any terminal windows for this to take effect. The utilities provided by the gem packages in your home directory will now have precedence over the system versions.
This means that you can type "rails" and the latest version will run, but you haven't messed with any of the software provided by Apple (apart from the system copy of RubyGems).
To upgrade your private copy of Rails whenever a new version comes along in future it's just this again:
gem update rails
just refer this....
