我正在使用一个用Jython开发的应用程序。当我尝试在里面使用inspect.py时，它显示了错误信息。

我的代码是这样的

import inspect,os,sys,pprint,imp
def handle_stackframe_without_leak(getframe):
    frame = inspect.currentframe()
    try:
        function = inspect.getframeinfo(getframe)
        print inspect.getargvalues(getframe)
    finally:
        del frame
#
def raja(a):
    handle_stackframe_without_leak(inspect.currentframe())
    print a
#
def callraja():
    handle_stackframe_without_leak(inspect.currentframe())
    raja("raja@ad.com")
#
callraja()
raja("raja@ad.com")
#

当我用python.exe运行这段代码时，没有任何问题。但是在应用程序里面运行时却出现了以下错误

 File "C:\Program Files\jython221ondiffjava\Lib\inspect.py", line 722, in getframeinfo

这可能会对你有帮助：http://grinder.sourceforge.net/faq.html#re-problems.

如果想快速检查一下，可以试着在 C:\Program Files\jython221ondiffjava\Lib\inspect.py 文件里的 findsource 方法中添加 import re。


def findsource(object):
    """Return the entire source file and starting line number for an object.
    (...snip...)"""
    import re
    file = getsourcefile(object) or getfile(object)

不过我不能保证一定有效……

你有没有试过在命令行上用Jython运行你的程序，也就是不通过应用程序来运行？当我用Jython 2.2.1或者Jython 2.5.0来运行你的程序时，得到的输出和用Python运行时是一样的。
