问题在于

pdf-writer-1.1.8/lib/pdf/writer.rb:712

，尤其是<代码>内容=“%PDF-{@version}\n%

任何建议都很好，我尝试用谷歌搜索错误，但我没有找到任何特定于pdf writer的内容。

pdf writer

与Ruby 1.9不兼容。有一个叉子是：

将GEM文件中的

pdf writer

行更改为：

gem 'pdf-writer', :git => 'git://github.com/metaskills/pdf-writer.git'

我刚刚将pdf writer移植到Ruby 2.0。将请求发送给metaskills（在前面的回答中引用）

如果您同时在Ruby 2.0中需要它，请在此处找到分叉代码：

gem 'pdf-writer', :git => 'git://github.com/mwlang/pdf-writer.git'

fork of pdf writer也适用于Ruby 2.1，谢谢

gem 'pdf-writer', :git => 'git://github.com/mwlang/pdf-writer.git'

看一看，工作得很有魅力，非常感谢。。。！我放弃了你的建议，它起作用了。。。部分原因是，我不知道是因为我在使用RVM，但每次我想运行应用程序时，我都必须导出RUBYOPT=-Ku，最糟糕的是，我无法通过终端生成任何新的控制器或模型，因为如果相同的错误发生，无论我是否导出。有什么建议吗？我不知道。尝试搜索其他类似的问题。我很久以前就解决了这个问题，但忘了发布答案，RVM文件系统中每个gemset都有一个文件夹，该文件夹中有一个配置文件，其中包含gemset的所有信息，添加

export RUBYOPT=-Ku

命令，您就可以开始了，这甚至解决了

create

和

destroy

命令
