Question

我正在使用这个Ruby代码，我希望在windowspc上使用exerb生成可执行文件。当我编译hello_world.rb时，使用此代码运行可执行文件没有问题 Exerb创建我的可执行文件但是当我运行它时我得到以下错误

undefined method `write' for File:Class (NoMethodError)

这里是代码

def replace text
  replacements = [
     {:pattern => /(^ARFD0001\|.*)(FAC_12125)/, :replace_with => '\1FAC_12102'},
     {:pattern => /^ARFD0001\|121\|25\|ZIEFAC\|/, :replace_with => 'ARFD0001|121|02|ZIEFAC|'},
     {:pattern => /(^ARFD0010\|.*)(12125203)(\d{3})/, :replace_with => '\112102181\3'},
     {:pattern => /(^ARFD0010\|.*)(2030341401)/, :replace_with => '\1181701500'},
     {:pattern => /(^ARFD0019\|.*)(12125203)(\d{3})/, :replace_with => '\112102181\3'},
     {:pattern => /(^ARFD0019\|\d*\|\d*\|\d*)(\|{2})/, :replace_with => '\1|PRINT|'},
     {:pattern => /^ARFD0009\|121\|25\|/, :replace_with => 'ARFD0009|121|02|'}
  ].each{|replacement|text.gsub!(replacement[:pattern], replacement[:replace_with])}
  text
end

Dir.glob("*.txt").each{|file|File.write(file, replace(File.read(file)))}
#line above gives the error in Exerb

如何实现这一目标？代码没有任何问题，在Ruby解释器中这是有效的，但似乎我必须告诉Execrb包含File类。

File类没有写方法。您必须先打开文件然后写入它。它可以这样做：

Dir.glob("*.txt").each do |file|
  File.open(file, 'w') {|f| f.write replace(File.read(file))}
end

Ruby Exerb：缺少File类
