Ruby 在尝试使用 Rudyscript2exe 时出现 "can' t 修改卡住字符串“错误

Question

我在这台 Mac 上有一个 ruby​​ 脚本，我想将它分发给 Windows 用户。我正在尝试使用 gem Rubyscript2exe 来制作可执行文件，但是当我运行以下命令时:

$ rubyscript2exe jabberbot.rb

我收到以下错误:

/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)

新问题:

按照回答替换代码后，我现在收到此错误:

您的问题是由于 ruby​​ 1.8.7 和 ruby​​1.9 中的规范更改引起的。 $0 引用了程序名，但它被卡住了。您使用的是最新版本的 rubyscript2exe 吗？如果没有，请尝试最新版本。如果问题仍然存在，那么按照rubyscript2exe的建议, 更改行:

$0.replace(realstuff)   if isapplication

对这些:

# $0.replace(realstuff)   if isapplication   # original
$__0 = realstuff   if isapplication          # added
alias $__0 $0                                # added
alias $0 $_0                                 # added
