我无法从使用Pmw(Python mega小部件)的python程序中创建可执行文件.我使用cx_Freeze(通过gui后端“Gui2Exe”).搜索Pmw站点我发现它是由Pmw库在运行时检查模块引起的,当你使用py2exe或类似程序时它不起作用,因为这些库是一个zip文件.更多信息可以在这里找到：http://pmw.sourceforge.net/doc/dynamicloader.html
因此,他们通过提供一个生成单个独立Pmw模块的脚本在“冻结Pmw”下的该页面中提供解决方案,您可以轻松冻结该模块.但是,该脚本使用已弃用的代码,不适用于Python 2.6.我试图修改它没有运气.

编辑：我想提一下,用’re’替换’正则表达式’是行不通的.

    if needColor:
    print '   ' + os.path.join(srcdir, 'PmwColor.py')

解决方法:

不幸的是,原始文件在制表符和空格方面存在一些问题(只需查看expandlinks中的while缩进).

我修复了那些缩进问题,用re.sub更改了regsub.gsub并使用字符串类型方法消除了字符串导入.

之后,脚本完美无缺：

   Pmw.py has been created.
   Before running freeze, also copy the following file(s):
   C:\Users\joaquin\Desktop\Pmw.1.3.2\src\Pmw\Pmw_1_3\lib\PmwBlt.py
   C:\Users\joaquin\Desktop\Pmw.1.3.2\src\Pmw\Pmw_1_3\lib\PmwColor.py

在这里你有更正的脚本：
