使用 ruby​​ 应用程序时出现 remove_entry_secure 错误

Question

我正在尝试使用 docsplit 将 PDF 文件拆分为图像。但看来我的 ruby​​ 安装有问题。我每次都收到以下错误：

/usr/lib/ruby/1.8/fileutils.rb:694:in `remove_entry_secure': parent directory is world writable

这是完整的命令行输出：

$ docsplit images pdf-test.pdf
/usr/lib/ruby/1.8/fileutils.rb:694:in `remove_entry_secure': parent directory is world writable, FileUtils#remove_entry_secure does not work; abort: "/tmp/d20130207-6739-1f9i6b" (parent directory mode 42777) (ArgumentError)

关于如何解决这个问题的任何想法？

原来我的/tmp 文件夹权限有问题。以下解决了问题：

我遵循的步骤是：

user@host-$: chmod 777 -R /tmp
user@host-$: chmod o+t -R /tmp
user@host-$: ls -l tmp
drwxrwxrwt 2 user group 4096 2009-11-21 17:01 tmp
