C# “导入正则表达式抛出”；全局变量'；i'；“未找到”；

我正在使用IronPython以c#运行我的脚本。这是我第一次使用IronPython，并且我已经正确地设置了它。脚本正常工作。但我需要添加一个“regex.compile（）”，为此，我需要导入regex

但一旦我这么做了，我就会从IronPython得到一个运行时异常，即“global name”I“未定义”

下面是有效的脚本-

def parse_failure(failure_string):
    if failure_string:
        try:
            failure_string = HTMLParser.HTMLParser().unescape(failure_string)
        except:
            pass
    return failure_string

这里是抛出异常的一个-

import regex

def parse_failure(failure_string):
    if failure_string:
        try:
            failure_string = HTMLParser.HTMLParser().unescape(failure_string)
        except:
            pass
    if (failure_string):
        LOG_START_PATTERN = regex.compile('(.+?)(begin\s+captured\s+(logging|stdout))')
        result = LOG_START_PATTERN.search(failure_string)
        if (result):
            end_pos = failure_string.find(result.group(0))
            if (end_pos != -1):
                return failure_string[:end_pos]

    return failure_string

例外情况详细信息-

不知道我做错了什么。这是python中预先存在的代码，我只是尝试在我的C#逻辑中调用它。

您试图导入的

regex

是什么？它是？是否有文档记录可用于IronPython？AIUI，该库包含一个C扩展模块，因此它只能从CPython（以及通过cpyext从PyPy）使用。另外：（1）您是否有一个名为

regex.py

的本地文件？（2） 你从C#那里怎么称呼这个？您是否确保正确设置sys.path？（3） 什么是完整的异常，而不仅仅是它的描述？regex.py位于我的C:\Python27\Lib\site包中。这就是现有代码所指的。我还将其添加到ScriptEngine的搜索路径列表中。在您的帖子中包含完整的错误回溯，这样我们就可以看到出现错误的代码行，而不是试图猜测它在哪里。知道它在您的网站包中的位置没有帮助；我们需要知道你从哪里得到它，它应该做什么（也许还有你是如何安装的）。
