ruby-on-rails - 安装 ruby​​ gems 时无法创建 Makefile

Question

我正在运行 OSX 10.8.2，Xcode 安装有命令行工具。

我正在尝试捆绑，并在一些 gems 上(我将在底部指定)我得到以下内容:

ERROR: Failed to build gem native extension

...

Could not create Makefile due to some reason

到目前为止，我在 gem 'pg' 和 gem 'binding_of_caller'

上遇到了错误

我认为该错误与无法创建 Makefile 有关，但找不到任何有助于解决该错误的方法。我在下面粘贴了完整的错误:

我不知道该怎么办。

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

An error occurred while installing pg (0.14.1), and Bundler cannot continue.
Make sure that `gem install pg -v '0.14.1'` succeeds before bundling.

编辑:我正在使用 rbenv 来管理 ruby​​ 版本，它说我正在运行 1.9.3 -p385The system ruby​​ is an older version, but that should据我所知这无关紧要。

我通过homebrew安装了postgresql

编辑 2:

我尝试切换到 RVM 进行 ruby​​ 管理，但出现另一个 make 错误:

Error running 'make -j2', please read ... ruby-1.9.3-p385/make.log
There has been an error while running make. Halting the installation.

文件 make.log 不存在...

您需要安装 postgres。来自 http://deveiate.org/code/pg/README_rdoc.html你需要:

• Ruby 1.8.7-p249 或 1.9.3-p0。
• PostgreSQL 8.3.x(带有 header 、-dev 包等)。

如果你用的是brew，就

brew install postgresql

至于 binding_of_caller，您使用的是什么版本的 ruby​​？
