在osx上安装pg gem时出错

时间：2011-04-23 04:17:47

标签： ruby-on-rails ruby macos gem pg

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 build

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。 ：（

答案 0 :(得分：15)

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.

最终正确安装了postgres并且问题已经解决了。

答案 1 :(得分：15)

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

答案 2 :(得分：7)

如果您在osx上使用PostgreSQL应用程序，则可能需要更改以下路径（因为二进制文件和配置文件的位置发生更改）而不是lesyk的答案中显示的路径：

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

我有同样的问题。对我来说，修复是：

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

对我来说有用的是Zag Zag的评论：

Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.

我也遇到过这个问题，对我来说答案是更新所有内容的RVM。 

rvm get head
rvm install 1.9.2

答案 6 :(得分：0)

我和你一样使用相同的OSX和XCode版本：使用pg 0.11.0的bundle install对我来说很好。 但是，我发现这篇文章可能对您有所帮助 fixing-the-you-have-to-install-development-tools-first-error-with-nokogiri

如果你正在使用rvm，你可以尝试：

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

简单的解决方案：

  1. 运行brew install postgresql
  2. 使用sudo权限安装gem：如下所示： sudo gem install pg -v '0.17.1'

答案 8 :(得分：0)

我被捆绑安装了3天。尝试添加 env ARCHFLAGS =＆＃34; -arch x86_64＆＃34; gem install pg - --with-pg-config = / usr / local / Cellar / postgresql / 9.3.5_1 /箱/ pg_config

我能够看到pg gem在此命令之后安装，但它仍然没有从bundle install安装，这很痛苦，因为我知道在Gemfile中写什么除了gem＆＃39; pg＆＃39;

最终对我有用的是发现我的pg_config位于 /Library/PostgreSQL/9.3/bin/pg_config 中，默认情况下，Gemfile包安装在/ usr / local / bin中查找/ pg_config

我刚刚运行了以下命令并且发生了魔法。 捆绑配置build.pg --with-pg-config = / Library / PostgreSQL / 9.3 / bin / pg_config

答案 9 :(得分：0)

一些纠正。对于那些使用自制软件安装postgres的人。

1）在〜/ .bash_profile

中写下以下行

导出ARCHFLAGS =＆＃34; -arch x86_64＆＃34;

2）重启控制台

3）执行以下命令

bundle config build.pg --with-pg-config = / usr / local / Cellar / postgresql / 9.3.5_1 / bin / pg_config （这必须是你的pg配置地址，可以每种都有所不同，具体取决于postgres的版本）

4）通过运行此命令在本地安装pg

sudo env ARCHFLAGS =＆＃34; -arch x86_64＆＃34; gem install pg - --with-pg-config = / usr / local / Cellar / postgresql / 9.3.5_1 / bin / pg_config

5）捆绑安装
