我正在使用 Ransack gem，但我想修改它。因此，我将 Ransack gem 文件夹从 C 驱动器复制到该vendor/plugins/static_gem文件夹并尝试对其进行编辑，但是当我启动服务器时，它给了我错误：

它在这些行给了我一个错误
s.files = `git ls-files`.split("\n")
s.test_files = `git ls-files -- {test,spec,features}/*`.split("\n")
s.executables = `git ls-files -- bin/*`.split("\n").map{ |f| File.basename(f) }
s.require_paths = ["lib"]
我能做些什么？
