我在使用 Ruby/Tk 使用 ocra 创建独立程序时遇到问题。首先，这是一个简单的测试程序：

require 'tk'

hello = TkRoot.new do
  title "Test" minsize(100, 40)
end

TkLabel.new(hello) do
  text "Tk version is #{Tk::TK_PATCHLEVEL}"
  pack { padx 15; pady 15; side 'left'}
end

Tk.mainloop

如果单独运行，这将正常工作。

如果我运行ocra tk-test.rb，应用程序会按预期弹出，但是当它终止时，会发生未处理的异常：

Ruby 是使用带有 MSYS2 开发环境的 Rubyinstaller 安装的。

红宝石版本是：

RUBY VERSION: 2.5.3 (2018-10-18 patchlevel 105) [i386-mingw32]

已安装的 gem 版本为：

ocra (1.3.10)
tk (0.2.0)

谷歌搜索表明其他人也有类似的问题，但答案似乎都已过时或不适用。例如，这个答案 看起来很有希望，但是我的环境中没有这样的目录C:\Ruby25\lib\tcltk\，所以它不适用。
