gem在mac上安装pg -v 0.12.2错误 [英] gem install pg -v 0.12.2 error on mac
问题描述
我是编程世界的新手，我有一段时间用ruby on rails解决了捆绑错误。我正在运行OSX 10.9.1，用于Ruby管理的RVM，以及我正在使用的ruby 2.1.1。
我收到的错误是：
Gem :: Ext :: BuildError：错误：无法构建gem原生扩展。
/Users/Removed/.rvm/rubies/ruby-2.1.1/bin/ruby extconf.rb
检查pg_config ... no
没有pg_config ...无论如何。如果构建失败，请再次尝试使用
--with-pg-config = / path / to / pg_config
检查libpq-fe.h .. 。
找不到'libpq-fe.h头文件
* extconf。 rb失败*
由于某些原因无法创建Makefile，可能缺少必要的
库和/或头文件。检查mkmf.log文件以获取更多详细信息。您可能
需要配置选项。
extconf失败，退出代码1
Gem文件将保持安装在/Users/Removed/.rvm/gems/ruby-2.1.1/gems/pg -0.12.2进行检查。
记录到/Users/Removed/.rvm/gems/ruby-2.1.1/extensions/x86_64-darwin-13/2.1.0/pg-0.12.2/gem_make.out
的结果一个错误安装pg（0.12.2）时发生，并且Bundler无法继续。
经过一番研究，我下载了Postgres应用程序并将其放入应用程序目录。看来我仍然有一个标题问题，所以我试着指定应用程序的include目录。仍然没有决议。我也遇到过一些关于自制的材料，但是我在这里设置的时候感到茫然。如果我可以得到解决一些帮助，将不胜感激。

检查我是否在子目录中是个好主意，但很遗憾我不是。我只是试图从应用程序的根目录引导服务器。

- with-pg-config = / path / to / pg_config
重新运行安装命令：
gem install pg --with-pg-config = / Applications / Postgres.app / Contents / MacOS / bin / pg_config
<这假设你在应用程序文件夹中有Postgres应用程序。你会遇到与Postgres.app的其他问题，但它是值得的通过他们的工作。 OS X中的每个应用程序实际上只是一个您可以查看的文件夹。如果你右键点击应用程序并选择显示内容，你会得到一个新的窗口，让你浏览应用程序文件夹的内容。
I'm new to the world of programming and I'm having a bit of a time resolving a bundling error with ruby on rails. I'm running OSX 10.9.1, RVM for Ruby management, and I am using ruby 2.1.1.
The error I receive is:
Gem::Ext::BuildError: ERROR: Failed to build gem native extension. /Users/Removed/.rvm/rubies/ruby-2.1.1/bin/ruby extconf.rb checking for pg_config... no No pg_config... trying anyway. If building fails, please try again with --with-pg-config=/path/to/pg_config
checking for libpq-fe.h... no
Can't find the 'libpq-fe.h header
* extconf.rb failed *
Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options. extconf failed, exit code 1
Gem files will remain installed in /Users/Removed/.rvm/gems/ruby-2.1.1/gems/pg-0.12.2 for inspection. Results logged to /Users/Removed/.rvm/gems/ruby-2.1.1/extensions/x86_64-darwin-13/2.1.0/pg-0.12.2/gem_make.out An error occurred while installing pg (0.12.2), and Bundler cannot continue.
After a little research I downloaded the Postgres App and put it into the Application directory. It appears I am still having a header problem as well, so I tried try specifying the include directory of the app. Still no resolution. Iv'e also came across some material relating to homebrew,but I'm at a loss for getting set up here. If I could have some help getting sorted out it would be greatly appreciated. Thank you in advance.

Checking to see if I'm in a subdirectory was a good idea, but sadly I'm not. I'm just trying to boot the server from the root directory of the application.
Try doing what it says:
--with-pg-config=/path/to/pg_config
so re-run the install command like:
gem install pg --with-pg-config=/Applications/Postgres.app/Contents/MacOS/bin/pg_config
This is assuming you have the Postgres app in your Applications folder. You will run into other issues with Postgres.app, but it's worth it to work through them. Every "App" in OS X is really just a folder that you can look into. If you right click on the app and choose "show contents" you will get a new window that will let you browse the content of the app folder.
