Python Pmw 和 cx_Freeze?
我在用cx_Freeze(通过图形界面工具“Gui2Exe”)把我的Python程序变成可执行文件时遇到了问题,这个程序使用了Pmw(Python Mega Widgets)。我在Pmw的网站上查找了一下,发现问题出在Pmw库在运行时检查模块的方式。当你使用py2exe或类似的程序时,它就不管用了,因为这些库被放在了一个zip文件里。更多信息可以在这里找到:http://pmw.sourceforge.net/doc/dynamicloader.html。 所以在那个页面的“冻结Pmw”部分,他们提供了一个解决方案,给出了一个脚本,可以生成一个独立的Pmw模块,这样你就可以轻松地把它冻结成可执行文件。不过,这个脚本使用了过时的代码,不能在Python 2.6及以上版本中运行。我尝试修改它,但没有成功。
补充一下,单纯把'regex'替换成're'是行不通的。

不幸的是,原始文件在制表符和空格方面有一些问题(你可以看看expandlinks
中的while
缩进)。
我修复了这些缩进问题,把regsub.gsub
换成了re.sub
,并且去掉了string
的导入,改用字符串类型的方法。
之后,脚本运行得非常好:
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
这里是修正后的脚本:
