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.<\/p>\n

I’m going to proceed without doing so, and hopefully things are fine.<\/p>\n
Step 3: <\/p>\n
vim .bashrc<\/pre>\nhuh, 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.<\/p>\n
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.<\/p>\n

Seguin (wayneeseguin@gmail.com) [http:\/\/rvm.beginrescueend.com\/]\r\nwcarss@quark:~$<\/pre>\n 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”<\/p>\n
*time passes*<\/p>\n
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<\/p>\n
chmod go-w \/home\/wcarss<\/pre>\n— 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 <\/p>\n
\/home\/wcarss\/.rvm\/rubies\/ruby-1.8.7-p302\/bin\/gem:4: warning: Insecure world writable dir \/home\/wcarss in \r\nPATH, mode 040733\r\n1.3.7<\/pre>\nNext up: problem 2. This one baffled me a bit longer. The problem arises when calling<\/p>\n
gem install sqlite3-ruby<\/pre>\nFirst, 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.<\/p>\n
Okay, lots of text there, so what in sam hill is wrong?<\/p>\n
