我有一个python脚本，它接受file.txt作为参数。

当我从windows命令行运行时，它会抱怨以下错误。

*C:\Projects\ATR220TA\ISO8583_Payment>python C:\Projects\ATR220TA\ISO8583_Payment\ISO8583.py C:\Projects\ISO8583.txt
Traceback (most recent call last):
  File "C:\Projects\ATR220TA\ISO8583_Payment\ISO8583.py", line 19, in <module>
    from ISO8583_Payment.ISOErrors import InvalidIso8583, ValueToLarge, InvalidValueType, InvalidBitType, BitInexistent, \
ModuleNotFoundError: No module named 'ISO8583_Payment'
C:\Projects\ATR220TA\ISO8583_Payment>pause*

基本上，ISO8583_Payment是我的主要项目的一个子文件夹，但出于某种原因，ISO8583_Payment被假定为一个模块，并抛出“模块未找到”一个错误。

ISO8583.py 8583.py

def ParseRawMessage(ISO8583TextFile):
    with open(ISO8583TextFile, 'rb') as in_file:
        contents = in_file.read()
        hex_bytes = binascii.hexlify(contents)
        IsoStr = hex_bytes.decode("ascii")
        Iso8583 = ISO8583()
        try:
            Iso8583.setIsoContent(IsoStr)
        except InvalidMTI as error:
            print("{0}".format(error))
        except InvalidBitType as error:
            print("{0}".format(error))
        except ValueToLarge as error:
            print("{0}".format(error))
        except InvalidValueType as error:
            print("{0}".format(error))
        except BitInexistent as error:
            print("{0}".format(error))
        except BitNotSet as error:
            print("{0}".format(error))
        except InvalidIso8583 as error:
            print("{0}".format(error))
        bitsAndValuesDictionary = Iso8583.getBitsAndValues()
        for v in bitsAndValuesDictionary:
            print('%s (BIT-%s) = %s' % (v['name'], v['bit'], v['value']))

@Mikah，当我从命令提示符运行时，您的建议不起作用。我之前提到过它对我有用，但是，我只是意识到它只有在我从pyCharm IDE运行时才能工作(很抱歉造成了混乱)。ISO8583.py和ISO8583Errors.py都位于ISO8583_payment文件夹中。此外，我按照您的建议在ISO8583_Payment文件夹中创建了ISO8583_Payment。

ISO8583.py 8583.py

import sys
sys.path.append("/ISO8583_Payment")
from ISO8583_Payment.ISOErrors import InvalidBitType,InvalidMTI,InvalidValueType,InvalidIso8583,ValueToLarge,BitInexistent,BitNotSet
''' I did not copy all the source code in here ''''

def ParseRawMessage(ISO8583TextFile):
    with open(ISO8583TextFile, 'rb') as in_file:
        contents = in_file.read()
        hex_bytes = binascii.hexlify(contents)
        IsoStr = hex_bytes.decode("ascii")
        Iso8583 = ISO8583()
        try:
            Iso8583.setIsoContent(IsoStr)
        except InvalidMTI as error:
            print("{0}".format(error))
        except InvalidBitType as error:
            print("{0}".format(error))
        except ValueToLarge as error:
            print("{0}".format(error))
        except InvalidValueType as error:
            print("{0}".format(error))
        except BitInexistent as error:
            print("{0}".format(error))
        except BitNotSet as error:
            print("{0}".format(error))
        except InvalidIso8583 as error:
            print("{0}".format(error))
        bitsAndValuesDictionary = Iso8583.getBitsAndValues()
        for v in bitsAndValuesDictionary:
            print('%s (BIT-%s) = %s' % (v['name'], v['bit'], v['value']))


if __name__ == '__main__':
    ParseRawMessage(sys.argv[1])

ISOErrors.py

class ValueToLarge(Exception):

    def __init__(self, value):
        self.str = value
    def __str__(self):
        return repr(self.str)

class BitInexistent(Exception):

    def __init__(self, value):
        self.str = value
    def __str__(self):
        return repr(self.str)       


class InvalidValueType(Exception):

    def __init__(self, value):
        self.str = value
    def __str__(self):
        return repr(self.str)       


class InvalidBitType(Exception):

    def __init__(self, value):
        self.str = value
    def __str__(self):
        return repr(self.str)       


class InvalidIso8583(Exception):

    def __init__(self, value):
        self.str = value
    def __str__(self):
        return repr(self.str)           


class InvalidMTI(Exception):

    def __init__(self, value):
        self.str = value
    def __str__(self):
        return repr(self.str)       

#Exception that indicate that bit is not there.
class BitNotSet(Exception):

    def __init__(self, value):
        self.str = value
    def __str__(self):
        return repr(

当我从命令提示符中运行时，仍然会得到以下错误。
