Python Pmw和cx_Freeze？ [英] Python Pmw and cx_Freeze?

问题描述

我无法从使用Pmw（Python大型小部件）的python程序中生成可执行文件。我使用cx_Freeze（通过gui后端 Gui2Exe）。在Pmw网站上搜索，我发现这是由于Pmw库在运行时如何检查模块而导致的，而当您使用py2exe或类似程序时，该库不起作用，因为该库位于zip文件中。可以在此处找到更多信息： http://pmw.sourceforge.net/doc/dynamicloader.html
因此，他们在该页面的冻结Pmw下提供了一个解决方案，方法是提供一个脚本，该脚本生成一个可以轻松冻结的独立Pmw模块。但是，该脚本使用了已弃用的代码，因此无法在Python 2.6 +中使用。我试图修改它，但是没有运气。

I am unable to make an executable from my python program which uses Pmw (Python mega widgets). I use cx_Freeze (through gui backend "Gui2Exe"). Searching Pmw site I've found that it's caused by how the Pmw library checks for modules when ran and it doesn't work when you use py2exe or similar programs because the libraries are in a zip file. More info can be found here: http://pmw.sourceforge.net/doc/dynamicloader.html So they give a solution in that page, under "Freezing Pmw", by providing a script which generates a single standalone Pmw module which you can easily freeze. However, that script uses deprecated code and won't work with Python 2.6 +. I've tried to modify it with no luck.

编辑：我想提一句，仅将'regex'替换为're'是行不通的。 / p>

I'd like to mention that just replacing 'regex' with 're' won't work.

推荐答案

不幸的是，原始文件具有制表符和空格存在一些问题（只需查看扩展链接中的 while 缩进）。

Unfortunately, the original file has some problems with tabs and spaces (just look at the while indentation in expandlinks).

我解决了那些缩进问题，将 regsub.gsub 更改为 re.sub 并消除了 string 导入，使用字符串类型方法。

I fixed those indentation problems, changed regsub.gsub with re.sub and eliminated the string import, using the string type methods.

此后脚本运行完美：

   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，您有更正的脚本：

Here you have the corrected script:
