麻烦安装pg gem [英] Trouble installing pg gem

问题描述

尝试安装pg gem会给我带来错误。

我使用的是使用rbenv / ruby​​-build构建的Ruby 1.9.3-p125。我使用一键式安装程序安装了PostgreSQL。我可以使用pgAdmin连接到数据库。

解决方案

不知道以下哪个步骤最终解决了这个问题。但是由于mu提到的太短，问题在于混合了32位和64位二进制文​​件。

• 1，我安装了这个 PostgreSQL的64位版本
2，我卸载了任何旧版的Homebrew OpenSSL安装
$ b


<$> $ brew卸载openssl










$ brew install --64位openssl

p>





• 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'

  
  

Trying to install the pg gem gives me errors.

I'm using Ruby 1.9.3-p125 built using rbenv/ruby-build. I installed PostgreSQL using the one-click installer. I'm able to connect to the DB using pgAdmin. I'm running out of ideas.

% gem install pg                                                                                                                                                                                                      ~

解决方案

Not sure which of the following steps finally cleared this issue up. But as mu is too short mentioned, the problem was mixing 32bit and 64bit binaries.

• 1st, I installed this 64-bit version of PostgreSQL

• 2nd, I uninstalled any old Homebrew OpenSSL installation

  $ brew uninstall openssl

• 3rd, I installed the 64-bit version of OpenSSL with Homebrew

  $ brew install --64-bit openssl

• Lastly, when installing the pg gem, I changed the LDFLAGS to point to the 64-bit version of OpenSSL

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