无法在Windows 7 x64上安装paperclip 2.5.0

Question

所有环境都是从railsinstaller设置的.Ruby - 1.9.2-p290 Rails - 3.1.1等

错误:G:\ Projects\burk> gem install paperclip -v'2.5.0'ERROR:执行gem时...(Errno :: EINVAL)无效参数 - C:/RailsInstaller/Ruby1.9.2/lib/ruby/gems /1.9.1/gems/paperclip-2.5.0/test/fixtures/question?mark.png

版本2.4.5安装正常,但在迁移时出错:

G:\ Projects\burk> gem install paperclip -v'2.5.0' - trace ERROR:执行gem时...(OptionParser :: InvalidOption)无效选项: - trace

G:\ Projects\burk> rake db:migrate --trace**调用db:migrate(first_time)**调用环境(first_time)**执行环境**调用db:load_config(first_time)**调用rails_env(first_time)**执行rails_env**执行db:load_config**执行db:migrate == CreateBrands:migration ============================= ====================== - create_table(:品牌)rake aborted!发生错误,所有后续迁移都已取消:

问题是有人添加了一个名为question?mark.pngGem测试文件的文件来测试Paperclip使用这些文件名的行为.不幸的是,问号不是Windows中文件名的合法字符.(参见目录,提交历史和讨论和问题)

最好的解决方法是从Github下载zip文件,将其复制到您的项目中并从Gemfile中明确引用Gem,如下所示:

gem 'paperclip', path: 'vendor/gems/paperclip'

编辑:作为或2.5.2版本,Paperclip gem可以再次安装在Windows平台上.(提交)
