尋找gem包
Ruby代碼
- gem search will_paginate --both (在local和remote源中search含有will_paginate關鍵字的)
- gem list -r will_paginate
- gem list -dr will_paginate (我常用這個)
查看gem包依賴其他的gem：

- Gem rails-2.3.5
- actionmailer (= 2.3.5, runtime)
- actionpack (= 2.3.5, runtime)
- activerecord (= 2.3.5, runtime)

Ruby代碼
- gem install hpricot --platform=mswin32 # 不指定在windows安裝會報錯
不安裝ri 和 rdoc
Ruby代碼
- gem install hpricot --no-ri --no-rdoc
查看更多的gem協助，可以
Ruby代碼
- gem -h
項目裡常用gem命令
Ruby代碼
- rake -T gems:
- (in /usr/local/system/entos/netposa_redmine)
- rake gems:build # Build any native extensions for unpacked gems
- rake gems:build:force # Force the build of all gems
- rake gems:install # Installs all required gems.
- rake gems:refresh_specs # Regenerate gem specifications in correct format.
- rake gems:unpack # Unpacks all required gems into vendor/gems.
- rake gems:unpack:dependencies # Unpacks all required gems and their dependencies into vendor/gems.
例如你enviroment.rb 中配置了paperclip gem
Ruby代碼
- config.gem ‘paperclip‘, ‘2.3.5‘
那麼
Ruby代碼
- rake gems:install
將會安裝paperclip 2.3.5 到你的ruby目錄裡,
Ruby代碼
- rake gems:unpack:dependencies
將會把依賴的gem包unpack 到vendor/gems 目錄下,
如果你是直接從gem包copy 到vendor/gems 目錄下的話,需要執行
Ruby代碼
- rake gems:refresh_specs
來產生 .specifications 檔案
