RVM causing path issues with installed gems on Ruby 1.9.2 - unable to annotate, etc, do I need to reinstall RVM?
I'm on Mac OSX Snow Leopard. I tried to post a similar question to the RVM Google group but it did not seem to get posted.
I'm worried that I've done something fundamentally wrong with my RVM install that's causing these errors, that seems to be related to paths, at each step of the way. Have any of you seen this behavior before?
I started to teach myself Rails programming as of about two months ago with a working environment of Ruby 1.9.1 and Rails 3.0.3, based on a hivelogic install tutorial that had me modify my ~/.profile file and install the relevant bits to ~/usr/local/src/. For reference, the line in my ~/.profile file was this when I installed RVM, if that makes any difference:
export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/usr/local/src:$PATH"
In my terminal I installed RVM as a user using the standard user github bash script.
I tried to install Ruby 1.9.2, which kept running into a weird error about a libfile somewhere. After much Googling I found someone on Stack Overflow that recommended renaming the ~/usr/local directory while performing the Ruby install -- I did this, and the install complete.
Then I did
gem install rails
and tried to dobundle install
in my app, which gave an error when trying to install the SQLite3 gem (even though I already had SQLite3 installed and working). Again, I spent a day Googling this and eventually found "Unable to install sqlite3-ruby gem" that said if I used Macports tosudo port install sqlite3
it would work.I tried that from the base directory, and Macports did its thing but it didn't fix the problem. Then I did the same thing from my app directory and it fixed the SQLite3 error I was getting.
Now I am able to run
rails server
andrails generate
again, which is great, but then I tried to "annotate" my new model, and I get this error: http://pastie.org/1481570
I have not yet solved this issue, and have looked at many threads of similar issues. This, for example, did not solve my problem: https://github.com/james2m/annotate_models/commit/5997da9692c9b222e8d1be22dfad6ed8638c16a1
I even tried copying my source code directly into the rvm/user/ directory in case that relative path was causing problems, but it doesn't seem to have fixed anything. Maybe I need to uninstall RVM and re-install it as root instead of a user-level thing?
What do you think is the best way to get annotate to work and hopefully get RVM to play nice with my gems going forward?
开发者_运维问答I'm unfortunately REALLY new to terminal, code, etc, so any help would be much appreciated.
On Snow Leopard you should modify either ~/.bashrc
or ~/.bash_profile
, preferably the later. Also, RVM will not need anything in ~/usr/local
since it's entirely self-contained in ~/.rvm
.
RVM uses a nice little shell function to sense the needed directories and desired default Ruby. I suspect either the instructions you followed were very out of date, or poor recommendations. The current RVM installation requests you add:
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # This loads RVM into a shell session.
to your ~/.bash_profile
The RVM site has lots of troubleshooting tips for things like MySQL. I'd strongly recommend backing out of the things those other tutorials had you do, and refer to the instructions on RVM's site. It is very easy to get things working right if you do it the RVM-way.
- Download and install Apple's latest version of XCode from their Developer site if you haven't already. There have been some broken versions shipped on the DVDs.
- Install. In particular follow the "Post Installation" section.
- Following that, do whatever
rvm notes
says to do as far as libraries. Following that, you should be able to uservm info
to gather useful info about your installation. It is your best friend. - Database integration will point you to how to fix MySQL's wagon.
- RVM development happens fast. Keep it updated, at least once a week using
rvm get head
.
At that point you should be in a good place to start reinstalling gems.
