麻烦安装pg gem

本文介绍了麻烦安装pg gem的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 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.

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'
