来自 Rails 和 Bundler 新手。

我能够在 MS Windows 7 上安装 rmagick 2.13.2：

gem install rmagick -v 2.13.2 -- --with-opt-lib=c:/ImageMagick/lib --with-opt-include=c:/ImageMagick/include --local

哪个有效，显示在此输出中：

Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...
Successfully installed rmagick-2.13.2
1 gem installed
Installing ri documentation for rmagick-2.13.2...
Installing RDoc documentation for rmagick-2.13.2...

但我无法让 bundler 使用我的 gemfile，其中包含以下行：

gem "rmagick"

但是命令：

bundle install --path vendor/bundle/

rmagick 上的错误如下：

Installing rmagick (2.13.2)
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension

An error occurred while installing rmagick (2.13.2), and Bundler cannot
continue.
Make sure that `gem install rmagick -v '2.13.2'` succeeds before bundling.

还，

>gem list rmagick

*** LOCAL GEMS ***

rmagick (2.13.2)

我检查并 rmagic 似乎安装在 vendor\bundle\ruby\1.9.1\gems\rmagick-2.13.2

因此，如果已安装，为什么 bundle install 会抱怨？我可以欺骗 bundler 并强迫它承认我做了什么吗？

TIA。

你应该像这样定义 rmagick gem：

gem 'rmagick', '~> 2.13.2', :platforms => :ruby
gem 'rmagick', '=2.13.2.mswin32', :platforms => :mswin

希望这会有所帮助。
