[英]Error with 'pg gem' installation when running 'bundle install'
我在運行'bundle install'時突然遇到這個問題。 一切似乎都正確安裝,但后來我遇到了'pg'的問題,正如許多其他人似乎做的那樣。 正如消息所說,我嘗試運行'gem install pg - '0.12.2'',但它仍然失敗。
我在Snow Leopard 10.6上,這是我得到的錯誤:
Installing pg (0.12.2) with native extensions
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

An error occurred while installing pg (0.12.2), and Bundler cannot continue.
Make sure that `gem install pg -v '0.12.2'` succeeds before bundling.
首先,您需要確保安裝了命令行工具(Xcode包)。 既然您使用的是OSX的舊版本 - 您將不得不研究如何做到這一點。
比,使用自制安裝postgress
brew install postgres
在那之后,一切都應該捆綁沒有問題。
您似乎沒有正確安裝postgres。 當我嘗試使用npm安裝pg模塊時,我遇到了類似的錯誤。 正確安裝postgres后它消失了。 這是下載鏈接: http : //www.postgresql.org/download/macosx/
如果僅在開機模式下在計算機上運行rails並使用sql lite,則無需安裝生產包。
所以如果你的gemfile像這樣:
group :production do
gem 'pg'
end
嘗試使用以下命令安裝軟件包:
gem install --without production
