rmagick gem安裝在windows上，但捆綁失敗

Question

來自Rails和Bundler的新手。

我能夠與微軟Windows 7安裝rmagick 2.13.2：

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

哪工作，在此輸出所示：

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... 

但我不能讓打捆使用我的Gemfile，包含行：

gem "rmagick" 

但命令：

個

bundle install --path vendor/bundle/ 

斷層上rmagick這樣的：

An error occurred while installing rmagick (2.13.2), and Bundler cannot

Make sure that `gem install rmagick -v '2.13.2'` succeeds before bundling. 

此外，

>gem list rmagick 

*** LOCAL GEMS *** 

rmagick (2.13.2) 

我檢查和rmagic似乎被安裝在供應商\包\紅寶石\ 1.9.1 \寶石\ rmagick -2.13.2

所以如果安裝了，爲什麼bundle安裝會抱怨？ 我可以欺騙打包商並強制它識別我所做的事或什麼？

TIA。

Answer 1

你應該定義rmagick寶石是這樣的：

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

希望這會有所幫助。
