Last time (and by last time, I mean earlier this evening), I wrote out a skeletal plan for how to install ruby and rails properly on a fresh 10.10 machine. I hadn’t yet tried the instructions, only gathered them from various blogs and searches – here is, step by step, the results of applying the instructions I wrote down earlier. I’ve taken the philosophy that seeing the actual content from the terminal is generally useful, so it’s all here, with explanations when things have gone wrong. The idea is that, next time I do this, I’ll know what the hell is going on.

hmmm, I’ve got a warning now that I have the environment variable RUBYOPT set; it’s set to “rubygems”, and the rvm docs recommended that I unset it. I’m going to proceed without doing so, and hopefully things are fine.
Step 3:
vim .bashrc
huh, it already has [[ -s “$HOME/.rvm/scripts/rvm” ]] && source “$HOME/.rvm/scripts/rvm” in it! This is pretty strange; but I’m happy. I also (fortunately) don’t have any return statements floating in my .bashrc, so I’m going to proceed to the next step.
Edit: Here is where I must insert this. It’s a week later, about 3 AM on the day after boxing day. I’ve just been trying to use heroku, and it turns out I was lacking several things in ruby because of some small errors I made at this step. I’ve had to uninstall ruby 1.9.2, install some libs and packages, and now I’m able to reinstall 1.9.2 and proceed. The following line of sudo apt-getting is not enough; in the ‘rvm notes’ above, they listed a bunch of things to install. I would suggest that you just do as they say, exactly. Install or update all of those packages, and that should be your step 4. Then, most of the craziness I deal with later on won’t happen to you. Good luck.
Step 4:
wcarss@quark:~$ sudo apt-get install libruby1.8 zlib1g-dev libssl-dev libreadline5-dev build-essential

Step 5:
wcarss@quark:~$ rvm install ruby-1.9.2
A RVM version 1.1.6 is installed yet 1.0.14 is loaded.
Please do one of the following:
* 'rvm reload'
* open a new shell
* source your shell init scriptswcarss@quark:~$
Whoops! I was supposed to run ‘source ~/.bashrc’ first – let’s do that.
Step 5 (fo realz):
wcarss@quark:~$ source ~/.bashrc
wcarss@quark:~$
No output: means all is well!
Step 6:
wcarss@quark:~$ rvm install ruby-1.9.2
A RVM version 1.1.6 is installed yet 1.0.14 is loaded.
Please do one of the following:
* 'rvm reload'

Huh. I’ll try ‘rvm reload’, and if that doesn’t work, I’ll log out and back in.

Installed RVM HEAD version:
rvm 1.1.6 by Wayne E. Seguin (wayneeseguin@gmail.com) [http://rvm.beginrescueend.com/]
wcarss@quark:~$
Hmm, doesn’t seem to have done anything. But in there, it says “If you wish to install rbx and/or Ruby 1.9 head (MRI) (eg. 1.9.2-head), then you must install and use rvm 1.8.7 first.” — so maybe we need to switch to 1.8.7 as default, run ‘rvm get head’ there, gem install something, and then we can make 1.9.2 work? We’ll give that a try if nothing super-promising comes out of a google search. Didn’t work. Googling “ruby-1.9.2-p0/bin/gem:4: warning: Insecure world writable dir”
*time passes*
Holy crap; it’s been a few hours but I’ve finally got the gorram thing. So, what’s wrong? Actually, two things. First off, let’s fix the ‘insecure directory’ thing. First was that my home directory, /home/wcarss, is world-writable! That’s pretty scary. So I called
chmod go-w /home/wcarss
— this leaves the u (for user, being the owner) setting of the directory with write access, and it removes write access for members of the same groups as me, and for assorted “other” users as well. ‘gem -v’ now just returns ‘1.3.7’ instead of
/home/wcarss/.rvm/rubies/ruby-1.8.7-p302/bin/gem:4: warning: Insecure world writable dir /home/wcarss in
PATH, mode 040733
1.3.7
Next up: problem 2. This one baffled me a bit longer. The problem arises when calling
gem install sqlite3-ruby
First, let’s clarify that we /do not/ want to use sudo for these gem installs. That isn’t the problem. Second, let’s clarify that whatever we’ve got set as the ‘default ruby’ is what version of gem we’re using — so for me, it’s 1.9.2 right now. While attempting to fix this problem, I switched to 1.8.7 for a while and the command worked well enough there. In 1.9.2 though, the problem persisted. You can specify a particular version to run by saying ‘rvm version command’, so, ‘rvm 1.9.2 gem -v’ will only call the 1.9.2 gem, even if you have 1.8.7 set as your default for the moment. Calling this without the version parameter, like so: ‘rvm gem -v’ will call gem for all installed versions, for me that’s both 1.8.7 and 1.9.2, in order.
Okay, lots of text there, so what in sam hill is wrong?
RVM grabs a source repo of ruby and then compiles it. So, I found a solution early on that matched my problem in a rough sense. It’s a fantastic collection of common ruby install issues and their fixes. It suggested that, if I’d built ruby from source, I should go and make/make install zlib. But to my naive mind, RVM wasn’t the same as installing by source.
Turns out, RVM does build from source, so it’s susceptible to the same issues. The fix to this stage of the problem, that will remove this:
ERROR: Loading command: install (LoadError)
no such file to load -- zlib
ERROR: While executing gem ... (NameError)
uninitialized constant Gem::Commands::InstallCommand
is to do:
cd ~/.rvm/src:
sudo apt-get install zlib1g-dev
cd ext/zlib
ruby extconf.rb
make
sudo make install
It worked as expected! I already had zlib1g-dev, the ruby script ran fine and generated a make file, the make file took about 15 seconds to compile the code, and sudo make install did a quick copy. Then I tried it again:
wcarss@quark:~$ gem install sqlite3-ruby

Huzzah! Finally, we can move on and try installing rails itself — it has a bunch of dependencies that it installs alongside it, so this is where, if something goes wrong, it’s some distant, barely required gem whose documentation will go insane and cause the install process to fail, borking up the whole environment. But here’s hoping it works okay:

Nooooooo! All I wanted to do was install mongrel! Let’s figure out what’s going on here.
*time passes*
Haha, okay. So, it looks like someone upstream buggered mongrel up a bit and left a bunch of “RSTRING(data)->ptr” patterns around when they should have been written as “RSTRING_PTR(data)”. There’s also some malformed case statements. If you go into ~/.rvm/gems/ruby-1.9.2-p0/gems/mongrel-1.1.5/ext/http11, you’ll see our culprit, http11.c. A full explanation of the fix we want can be found here – with a few small edits.
I don’t think the sudo’s are a good idea for us; they’re just there in case you’re working in a system directory. Given that our whole install has proceeded through RVM, which should be inside of your home directory, we’re fine without it. I followed the form on ‘sudo make install’ though, as it feels like a good idea to install things as root. Beyond that, it seemed prudent to run ‘ruby setup.rb’ from within the mongrel-1.1.5 directory, just to make sure that things close off right. So, in succinct form (I’m overlapping with the website I linked here):
cd ~/.rvm/gems/ruby-1.9.2-p0/gems/mongrel-1.1.5/ext/http11
vim http11.c (generally, "RSTRING(data)->thing" becomes "RSTRING_THING(data)")
make the edits suggested at the other site
cd ../../lib/mongrel
vim handlers.rb
fix the case statements from 208-212 (replace ':' with 'then')
gem install gem_plugin (we're avoiding sudo)
cd ../../
ruby setup.rb
And you’re done. Now, let’s test this out. It’s been a bit over 4 hours since I started working on this, so… high hopes. 🙂

rake db:create
rails s
‘new example’ makes a folder called ‘example’ for you, so don’t worry about polluting your space. ‘bundle install’ seems to.. do some kind of magic with gems? I’m not sure. And rake db:create told me that my database already exists:
wcarss@quark:~/code/ruby/testing/example$ rake db:create
(in /home/wcarss/code/ruby/testing/example)
db/test.sqlite3 already exists
db/development.sqlite3 already exists
then ‘rails s’ starts the server, we open up a new tab, and head to servername:3000:
Huzzah!
A bit over 4 hours. That’s a hell of a process to go through to get a thing running. I’m concerned that it might bork up magically in the next few months during an update (that’s what happened to my last one; ubuntu just *forgot* that ruby was installed somehow — it was fun), but at least it’s all under rvm now, and theoretically I can just remove and then reinstall a whole borked ruby environment. If things go too far astray, I can just delete all of rvm! This is the safest I’ve felt about these things in a while.
If something here worked very differently for you, or you’ve got comments, certainly let me know. I can’t promise I’ll be able to fix some problem you’re running across, but I’d like to think I’d give it a try. Thanks for reading; good luck.
