我在这台Mac上有一个ruby脚本,我想分发给Windows用户。我正在尝试使用gem Rubyscript2exe来创建可执行文件,但是当我运行以下命令时:

$ rubyscript2exe jabberbot.rb

我收到了以下错误:

/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 / ruby​​script2exe的第19行是

load Gem.bin_path('rubyscript2exe', 'rubyscript2exe', version)

将代码替换为已回答后,我现在收到此错误:

您的问题是由于ruby 1.8.7和ruby1.9中的规范更改造成的。 $0指的是程序名称,但它被冻结了。您使用的是rubyscript2exe的最新版本吗?如果没有,请尝试最新版本。如果问题仍然存在,那么,如rubyscript2exe所示,更改行:

$0.replace(realstuff)   if isapplication

到这些:

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