在osx上安装pg gem时出错

Question

我在osx 10.6.7尝试在新的rails 3.0.7应用程序上运行bundle install,并且在尝试构建pg gem时它仍然失败.它一直告诉我,我需要开发人员工具.但据我所知,我已经安装了开发人员工具.

这是xcodebuild -version的输出

Xcode 3.2.6
Component versions: DevToolsCore-1809.0; DevToolsSupport-1806.0
BuildVersion: 10M2518

这是失败的pg gem构建的输出

任何帮助都会非常感激.仅供参考我还尝试使用mysql构建应用程序,并且基本上获得了相同的堆栈.所以我很确定我缺少某种开发人员构建工具,但我只是不知道哪些工具.:(

Answer 1

在Rails应用程序中运行bundle install时,我遇到了完全相同的问题.我安装了自制软件然后运行

brew install postgresql. 

这最终正确安装了postgres,问题对我来说是固定的.

Answer 2

1. export ARCHFLAGS =' - arch x86_64'
2. export PATH =/Library/PostgreSQL/9.1/bin:$ {PATH}
3. 宝石安装pg

Answer 3

如果您在osx上使用PostgreSQL应用程序,您可能需要更改以下路径(如二进制文件和配置文件的位置更改)而不是lesyk的答案中显示的路径:

export PATH=/Applications/Postgres.app/Contents/MacOS/bin:${PATH}

Answer 4

对我有用的是 Zag Zag 的评论：

~/projects/foo$ env ARCHFLAGS="-arch x86_64" gem install pg
Building native extensions.  This could take a while...
Successfully installed pg-0.11.0
1 gem installed
Building YARD (yri) index for pg-0.11.0...

~/projects/foo$ bundle 
...
Using pg (0.11.0) 
...
Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.

Answer 5

我遇到过同样的问题.对我来说,修复是:

sudo ln -s gcc /usr/bin/gcc-4.2

Answer 6

我使用的 OSX 和 XCode 版本与您相同：使用 pg 0.11.0 进行捆绑安装对我来说效果很好。但是，我发现这篇文章可能可以帮助您 修复您必须安装的开发工具的第一个错误与 nokogiri

如果您使用的是rvm，您可以尝试：

rvm update head  
rvm --force install
1.9.2 gem install bundle
