使用 Brew 和 RVM 在 MacOS X 中安裝乘客

#Install RVM    
bash <<( curl http://rvm.beginrescueend.com/releases/rvm-install-head )

#Install ruby 1.9.2
rvm install 1.9.2

# Set as default
rvm --default 1.9.2 

# Install passenger in the global gemset
rvm @global gem install passenger       

# Install Nginx                                  
brew install nginx --with-passenger

cp /usr/local/Cellar/nginx/0.8.54/org.nginx.plist ~/Library/LaunchAgents
launchctl load -w ~/Library/LaunchAgents/org.nginx.plist        

# Decompress the source of Nginx.
cd $HOME/Library/Caches/Homebrew
tar xvf nginx-0.8.54.tar.gz                       

# Now install the nginx module
passenger-install-nginx-module

# Chose to configure to customise your own Nginx installation

# The source code for nginx is here:
/Users/Nerian/Library/Caches/Homebrew/nginx-0.8.54                             

# Chose to install nginx to:
/usr/local/Cellar/nginx/0.8.54/sbin

# Click intro in the next two questions.

# At the end of the install it says that it modified nginx config file. I don't use that file. I Edit /usr/local/etc/nginx/nginx.conf and add the snippet that the passenger install outputed.

寶石文件

source 'http://rubygems.org'

gem 'rails', '3.0.4'                                                     
gem "mongoid", "2.0.0.rc.7"
gem "bson_ext", "~> 1.2"
gem 'launchy'

group :development, :test do
 gem 'rspec-rails'
 gem 'machinist_mongo', :require => 'machinist/mongoid', :git => 'http://github.com/nmerouze/machinist_mongo.git', :branch => 'machinist2'
 gem 'steak'
 gem 'capybara'
 gem 'spork', '~> 0.9.0.rc'
 gem "fuubar"  
end

/etc/hosts 配置：

127.0.0.1 davinci.dev

我得到這個錯誤：

http://davinci.dev:8081/

http://github.com/nmerouze/machinist_mongo.git（在 machinist2 處）未檢出。請執行bundle install

該 gem 安裝在 gemset DaVinci 中。我確實執行了捆綁安裝。它已安裝，但乘客沒有找到它。如果我刪除了那個 gem，那麼我會得到相同的錯誤，但會出現另一個 gem。等等等等。因此，Passenger 沒有找到寶石組。我可以使用rails s執行該項目。

我已經花了大約 4 個小時，但沒有找到 F###### 錯誤。你看出什麼不對了嗎？

用 rvm get head 解決。似乎有一個錯誤或某些東西沒有保存 gemset 的“受信任”狀態。
