I have updated the assignment to require 3.4.0 or later. So 3.6.2 should be fine.

Hi,
I've installed Ruby and the Gems as described above (rails, sqlite3-ruby, mongrel). No errors reported on the installations.
When I run the versions.rb script, I get an error: "Sqlite: Exception: (eval):1:in ``': No such file or directory - sqlite3 -version"
The full output is below.

IF YOU HAVE ALREADY INSTALLED Sqlite3, then you may need to add it to your path: Control Panel / System / Advanced tab / Environment Variables button
Then find Path under "System variables" click the edit button, and add the path at the end, e.g., if your path is, say:
C:\PROGRAM FILES\FOOBAR [probably very long . . .]
change it to
C:\PROGRAM FILES\FOOBAR;C:\path\to\sqlite3
Don't forget the semi-colon that goes between each path.

Hi,
Yep... used the "One-Click Installer", followed by the gem install on the various Gems.
I downloaded sqlite3.exe and sqlite3.dll from the site you suggested and placed them into the sqlite3 lib directory created as part of the gem install. I added in this directory into the PATH.
All appears to be OK now.
Thanks! Mike

For those who are doing this in OSX 10.5, make sure you update Gems before you use it to update Rails. If you don't use the updated version of Gems to execute 'gem update rails', it doesn't seem to know which version it has and you will end up with two versions of rails and some broken links in whatever system variables Rails is using to know which version it is. The rails website leads you to believe that you should run 'gem update rails' as the first step then run the setup.rb script to update gems.
If you do go down this path, run 'gem uninstall rails' and pick the latest version. Then use the newly installed Gems to re-run 'gem update rails'. After that, everything should work OK.
It's Dave, actually. I may be off the map for what the book says. I haven't bought it yet, and I don't want to mislead anyone. But I think a pretty solid overall point to make is that Gems gets updated first.
Step 1 is actually making sure that XCode is installed on your system. That sets you up with Rails 1.2.6 and Gems 1.0.
I didn't realize that Gems had a flag for self-updating. What I did was per the ruby on rails download page.. Instead of updating Rails first, I went to the link for downloading Gems
Then I used Gems to update Rails. In Terminal type "gem update rails". Gems is pretty key because its the package manager.
jgn

Thanks Dave -- Sorry about the name mistake.
There are a lot of good reasons to update the gem system first (with gem update --system). Among them is the fact that newer versions of gem automatically pull in all dependent packages; before, you would have to ask explicitly for dependency inclusion.

An older version of XCode on my Mac prevented me from installing sqlite3-- "C compiler cannot create executables" was the error at the configure stage. Only after I updated XCode did the install run smoothly.
I cannot execute the puts `gems list --local` command from irb command line; it errors out as in the upper right corner in the picture: Exec format error - gem list --local(Errno::ENOEXEC) from version.rb:33
I CAN type gem list at the system cmd line and get the output you see in green text (all my gems).
I have the correct environment paths (seen in picture), and I have closed the command windows and reopened them. Not sure what to do next. The error happens whether I run versions.rb in the SCiTe program or from the command line (ruby versions.rb).

Well, before I go to bed...I saved the command
gem list --local
into a batch file and named it gemlist.bat
in my versions.rb I changed the last line to
puts 'gemlist.bat'
and that works fine. So I guess windows can execute gems commands in windows space but ruby tools cannot.
Ideas appreciated :)

FIXED
In order to execute puts 'gem list --local' in a ruby program, I have to replace it with a slightly different version of the command....
puts 'gem.bat list --local' <--this works from within versions.rb
Interesting. I guess ruby doesn't play perfectly with windows - no execution bit to tell it what to do like in Linux? So it has to have the .bat extension? Ahhh, the mystery.

I’m using Windows XP SP 3.
I had great difficulty with the Zlib::BufError problem. It would even happen running “gem update –system” a second time.
Finally I uninstalled everything to start again (remembering to also delete the .gem directory in my windows home directory "\Documents and Settings\myname").
The solution that worked for me was to reboot after each and every gem update operation. I don’t know why that worked but it did (and nothing else had). This problem is discussed extensively on the web but there’s no universal solution.

Thanks for mentioning this, David. I didn't have to uninstall anything. I merely shut down my system on Friday, and after booting this evening, when I tried installing the mongrel gem again, it installed with no problems at all.

After installing Xcode, it magically worked. Beware that Xcode is a 1GB DVD sized download. Also, I had to register for an Apple Developer account to download.
Another note worth mentioning: AWDR says to go to http://darwinports.com/install/ to install darwin ports. However, the site has been down for a few days and now it's back online, but the downloads are still not working. So I may have resolved it quicker with darwin ports, but it's still not available.
I still think Xcode was worth it since it's in the list of IDE's in AWDR. I'm gonna give it try along with the other ones.

Fedora 9 Linux : For those of us that don't know when to quit, you should install ruby-devel , as well as GCC , in addition to the standard RPMs ( ruby , ruby-lib , ... )
# yum install gcc # yum install ruby-devel
ruby-devel includes the 'ruby.h' file which was preventing my proper installation of Mongrel and FastThread .
The ruby versions.rb works on my laptop, but thwn I do the same exact steps on my desktop I get:

Two things:
(1) I say about, if you have issues with the sqlite3-ruby gem, try an earlier version:
gem install --version 1.2.3 sqlite3-ruby
(that's two dashes)
(2) If it still doesn't work: What is very very likely to be happening is that something is objecting to the spaces in the path.
I would strongly suggest that you install everything at the root. I.e., Ruby should be in C:\Ruby, Sqlite3 in C:\sqlite3, etc.

Here are some questions and suggestions:
0. If you are local and you're on a laptop, bring it to section. 1. What happens when you type "sqlite3" into the DOS prompt? Does that work? 2. Review the screencast, and consider installing Sqlite3 the way it is done there. Incidentally, there is also a .def file -- did you put that in ruby/bin as well? In any case, I think you'll be happier in the long run if you put sqlite3 in its own directory and change your path (see the screencast).
MJG
· 1 year ago
Thank you its working now - the screencast says to place the files into the Ruby>Bin directory, however that didn't work for me so I did what you suggested above (place the three files into the sqlite3 directory created by the gem install, changed the path) and now versions.rb runs without generating that error.

The solution that worked for me was to reboot after each and every gem update operation. I don’t know why that worked but it did (and nothing else had). This problem is discussed extensively on the web but there’s no universal solution.
I didn't have to uninstall anything. I merely shut down my system on Friday, and after booting this evening, when I tried installing the mongrel gem again, it installed with no problems at all.
- On the syllabus it says: Sunday, Oct. 5: Assignment 1 (Ruby One-Liners) due and there is no date for Assignment 0
- On the assignment 0 page it says due Sunday, Oct. 5
- On the assignment 1 page it says due Sunday night, Oct. 19.
So I just want to be sure. Do I hand in BOTH assignments 0 & 1 on Oct 5?
Thanks!

SOLUTION: I fixed it after I found this similar error in the Ruby Forums:
http://railsforum.com/viewtopic.php?id=22116
After installing Xcode, it magically worked. Beware that Xcode is a 1GB DVD sized download. Also, I had to register for an Apple Developer account to download.
Another note worth mentioning: AWDR says to go to http://darwinports.com/install/ to install darwin ports. However, the site has been down for a few days and now it's back online, but the downloads are still not working. So I may have resolved it quicker with darwin ports, but it's still not available.
I still think Xcode was worth it since it's in the list of IDE's in AWDR. I'm gonna give it try along with the other ones.
I had to install a couple of extra packages to get mine working:
$ sudo apt-get install ruby1.8-dev
$ sudo apt-get install rails
Also, I had to run "rails" with a special argument to force it to use sqlite3. By default, it tried using MySQL.
$ rails -D sqlite3 assn0
Hope this helps...
rails -v
sudo gem -v
RubyGems version 1.1.1
Rails version 2.0.2
gem update rails
Then new apps should get Sqlite3 not MySQL.
# yum install gcc
# yum install ruby-devel
ruby-devel includes the 'ruby.h' file which was preventing my proper installation of Mongrel and FastThread .

I followed all instructions from the video, still no positive results. Any suggestions to solve this problem? Thanks.
(1) I say about, if you have issues with the sqlite3-ruby gem, try an earlier version:
gem install --version 1.2.3 sqlite3-ruby
(that's two dashes)
(2) If it still doesn't work: What is very very likely to be happening is that something is objecting to the spaces in the path.
I would strongly suggest that you install everything at the root. I.e., Ruby should be in C:\Ruby, Sqlite3 in C:\sqlite3, etc.

I placed both the sqlite3.dll and the sqlite3.exe into the ruby/bin directory and installed the gem without issue so I'm unsure why this error is occurring. I would greatly appreciate any suggestions or help anyone might have.
0. If you are local and you're on a laptop, bring it to section.
1. What happens when you type "sqlite3" into the DOS prompt? Does that work?
2. Review the screencast, and consider installing Sqlite3 the way it is done there. Incidentally, there is also a .def file -- did you put that in ruby/bin as well? In any case, I think you'll be happier in the long run if you put sqlite3 in its own directory and change your path (see the screencast).
Thanks for your help!
