我在这台Mac电脑上有一个Ruby脚本，我想分发给Windows用户。我试图使用gem Rubyscript2exe来生成可执行文件，但是当我运行以下命令时：
$ rubyscript2exe jabberbot.rb
我得到以下错误：
/Library/Ruby/Gems/1.8/gems/rubyscript2exe-0.5.3/bin/rubyscript2exe:5:in `replace': can't modify frozen string (TypeError)
from /Library/Ruby/Gems/1.8/gems/rubyscript2exe-0.5.3/bin/rubyscript2exe:5
from /usr/bin/rubyscript2exe:19:in `load'
from /usr/bin/rubyscript2exe:19
/Library/Ruby/Gems/1.8/Gems/rubyscript2exe-0.5.3/bin/rubyscript2exe是
gemdir = File.expand_path("..", File.dirname(__FILE__))
realstuff = File.expand_path("realstuff.rb", gemdir)
isapplication = File.basename(File.dirname(__FILE__)) == "bin"
$0.replace(realstuff) if isapplication
load(realstuff)
/usr/bin/rubyscript2exe的第19行是
load Gem.bin_path('rubyscript2exe', 'rubyscript2exe', version)
新版本：
在将代码替换为已回答的代码后，我现在收到以下错误：

最佳答案
您的问题是由于ruby1.8.7和ruby1.9中的规范更改造成的$0指程序名，但已冻结您正在使用最新版本的rubyscript2exe？如果没有，试试最新的版本。如果问题仍然存在，则按照rubyscript2exe的建议更改行：
$0.replace(realstuff) if isapplication
致：
# $0.replace(realstuff) if isapplication # original
$__0 = realstuff if isapplication # added
alias $__0 $0 # added
alias $0 $_0 # added
