山狮队的pg gem'0.14.0'失败 [英] pg gem '0.14.0' on Mountain Lion fails

问题描述

我刚从OS X Lion升级到OS X Mountain Lion。
大多数情况下，我的rails环境保持完好。

为了让事情恢复到良好的状态，我必须采取的唯一步骤是：
- 安装XCode 4.4
- 安装XCode 4.4命令行工具
- 安装gcc-4.2

所以一切顺利。

下面是这个问题，当我运行bundle install时，几乎所有的gem都安装正确，除了我需要的最重要的一个 - postgresql gem'pg'。

对于0.12.2以上的版本，它特别失败。

我使用ruby 1.9.3p125。

我可以成功获取0.12.2 pg gem和以下版本，但它们给了我分段错误（我猜是因为我使用的ruby版本）。

所以这让我相信它是特定于pg gem的，而不是我的整体环境，因为其他宝石安装正常。

我也尝试重新安装Postgresql以确保我的postgres环境没问题d

有没有人能够安装'pg'宝石版本0.13.0或更高版本（更可取的是0.14.X）？

解决方案

Deefour的评论得到了它！这是我安装PostgreSQL的方式。

我使用PostgreSQL的一键安装程序，我猜测它并没有为Mountain Lion正确设置libpq。 / b>

另一方面，Homebrew会为操作系统正确地构建它。

通过自制软件安装postgres后

  brew install postgresql 
  

我能够安装我的宝石没有问题。

谢谢大家！

I just upgraded from OS X Lion to OS X Mountain Lion. My rails environment for the most part stayed in tact.

The only steps I had to do to get things back to a good state was: - Install XCode 4.4 - Install XCode 4.4 Command Line Tools - Install gcc-4.2

So all that went well.

Here's the issue, almost all my gems install properly when I run bundle install except for one of the most important ones I need - the postgresql gem 'pg'.

And it specifically fails for versions above 0.12.2.

I'm using ruby 1.9.3p125.

I can successfully grab the 0.12.2 pg gem, and versions below, but they give me segmentation faults (I'm guessing because of the version of ruby I'm using).

So this leads me to believe that it's specific to the pg gem, and not my overall environment seeing as other gems install fine.

I also tried re-installing Postgresql to ensure my postgres environment is ok and seems good on that front.

Has anybody been able to install the 'pg' gem version 0.13.0 or above (and more preferrably 0.14.X)?

Here is my stack trace:

Gem files will remain installed in /Users/caseyli/.rvm/gems/ruby-1.9.3-        p125@elliottfarmequipment/gems/pg-0.14.0 for inspection.

解决方案

Deefour's comment got it! It was the way I installed PostgreSQL.

I use the PostgreSQL one-click installer which I'm guessing doesn't set up the libpq up properly for Mountain Lion.

Homebrew on the otherhand will build it properly for the OS.

After installing postgres through homebrew

brew install postgresql

I was able to install my gem no problem.

Thanks everybody!
