尝试启动visualruby产生了这个：

F:/projects/static/tools/Ruby23/lib/ruby/gems/2.3.0/gems/gobject-introspection-3.0.9-x86-mingw32/lib/gobject-introspection/loader.rb: line 302
   GLib-GObject-WARNING **:attempt to override closure->va_marshal (63C488A0) with new marshal (04D05CD0)

Did you mean?  initialize_new_from_inline
               initialize_new_from_file_utf8
               initialize_new_from_bytes
               initialize_new_from_stream
               initialize_new_from_data
        from...

所以我打开文件并用initialize_new_from_file_utf8替换了调用。启动visualruby现在会显示GUI，但命令提示符中还会出现几个警告：

提供的演示运行良好，但这让我有点担心。我没有安装其他版本的所需宝石。如何修复我的vr安装？

编辑：示例程序本身运行正常，glade不会
