安装pg gem出现问题

8

尝试安装pg gem时出现错误。

我使用的是rbenv/ruby-build构建的Ruby 1.9.3-p125。我使用一键安装程序安装了PostgreSQL。我能够通过pgAdmin连接到数据库。但目前我已经没什么头绪了。

% gem install pg                                                                                                                                                                                                      ~

你从哪里获取了你的libssl？听起来你可能正在尝试混合32位和64位二进制文件。 - mu is too short

我认为只需使用 brew install openssl - Sandro

我认为你关于混合两者的想法是正确的，但我不知道是否可能或如何强制Homebrew将openssl构建为64位。 - Sandro

不确定以下哪个步骤最终解决了这个问题。但是，正如mu is too short所提到的那样，问题在于32位和64位二进制文件混合使用。

第一步，我安装了 PostgreSQL的64位版本
第二步，我卸载了任何旧的Homebrew OpenSSL安装

$ brew uninstall openssl
第三步，我使用Homebrew安装了64位版本的OpenSSL

$ brew install --64-bit openssl
最后，在安装pg gem时，我将LDFLAGS更改为指向64位版本的OpenSSL

$ gem install pg -- --with-ldflags='-L/usr/local/Cellar/openssl/0.9.8s'
