A new operating system means taking a few minutes to upgrade Homebrew. Here is how I went through the process.
You've installed Mac OS X Yosemite, and now it's time for that feared task -- upgrading Homebrew.
brew wouldn't work at all. I saw this error:
/usr/local/bin/brew: /usr/local/Library/brew.rb: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby: bad interpreter: No such file or directory
This was fixed by changing
1.8 on the first line of
/usr/local/Library/brew.rb to "Current." Found that trick here.
Next, I went to upgrade Homebrew.
$ brew upgrade
Then I ran into an error with Bundler and OpenSSL, since Apple has ditched OpenSSL for their own encryption library. My error from running
bundle install was:
Symbol not found: _SSLv2_client_method (LoadError)
This was fixed by relinking
gcc and reinstalling the version of Ruby I was using.
$ export CC=/usr/bin/gcc $ rbenv install 2.1.0 rbenv: /Users/sean/.rbenv/versions/2.1.0 already exists continue with installation? (y/N) y
When trying to run a Rails project, I started with this issue related to RMagick:
This installation of RMagick was configured with ImageMagick 6.8.8 but ImageMagick 6.8.9-8 is in use. (RuntimeError)
Removing the bundle and trying to reinstall, like so:
$ rm -rf .bundle $ bundle install
Led to another error, this time from nokogiri:
Building nokogiri using packaged libraries. ----- libiconv is missing. please visit http://nokogiri.org/tutorials/installing_nokogiri.html for help with installing dependencies. ----- extconf failed, exit code 1
This was fixed using the following commands:
$ xcode-select --install $ gem uninstall nokogiri $ gem install nokogiri $ rbenv rehash
Here are a few important notes regarding this issue:

I had installed postgres via Homebrew and the upgrade to Yosemite removed some directories. Follow this advice I was able to get postgres running again.
$ mkdir /usr/local/var/postgres/pg_tblspc $ mkdir /usr/local/var/postgres/pg_twophase $ mkdir /usr/local/var/postgres/pg_stat_tmp
It may start automatically after that. If not, you can run:
$ brew info postgres
And at the bottom, you'll see some instructions on how to proceed. Something like this:
To have launchd start postgresql at login: ln -sfv /usr/local/opt/postgresql/*.plist ~/Library/LaunchAgents Then to load postgresql now: launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist Or, if you don't want/need launchctl, you can just run: postgres -D /usr/local/var/postgres
Feel free to let me know if you run into other quick fixes I should add to this article.
You've been handed a design and tasked with writing the code that will bring that design to life. Where do you start?
