无法在 Windows 7 x64 上安装回形针 2.5.0

Question

所有环境都是从 railsinstaller 设置的。 红宝石 - 1.9.2-p290 Rails - 3.1.1 等

错误： G:\Projects\burk>gem 安装回形针 -v '2.5.0' 错误：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

2.4.5 版安装正常，但迁移时出错：

G:\Projects\burk>gem 安装回形针 -v '2.5.0' --trace 错误：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 ** 执行数据库：迁移 == CreateBrands：迁移 ============================================== ====== -- create_table(:brands) 耙中止！ 发生错误，所有后续迁移均已取消：

Answer 1

问题是有人在 Gem 测试文件中添加了一个名为 question?mark.png 的文件，以使用此类文件名测试 Paperclip 的行为。不幸的是，问号不是 Windows 中文件名的合法字符。 （见directory，提交history和discussion和issue）

最好的解决方法是下载zip file from Github，将其复制到您的项目中，然后从您的 Gemfile 中明确引用 Gem，如下所示：

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

编辑： 作为或版本 2.5.2，Paperclip gem 可以在 Windows 平台上再次安装。 (Commit)
