[英]module not found when python script run from command line
ISO8583.py
和ISO8583Errors.py
都位于ISO8583_payment
文件夹内。 另外,我在ISO8583_Payment
文件夹中创建了虚拟__init.py__
。 从命令行运行 ISO8583.py 时,它会抛出一个错误。 但是当我从 pyCharm IDE 运行时它可以工作。
ISO8583.py

sys.path.append("/ISO8583_Payment")

当我从命令提示符运行时,出现以下错误。
C:\Projects\ATR220TA_Work_On_Progress\ISO8583_Payment>python C:\Projects\ATR220TA_Work_On_Progress\ISO8583_Payment
C:\Users\gobiraaj.anandavel\AppData\Local\Programs\Python\Python37-32\python.exe: can't find '__main__' module in 'C:\\Projects\\ATR220TA_Work_On_Progress\\ISO8583_Payment'
尝试以下操作:
import os
import sys
sys.path.append(os.path.realpath(os.path.dirname(os.path.dirname(__file__))))
文件名是ISO8583Errors.py
还是ISOErrors.py
?
这取决于你必须使用
from ISO8583_Payment.ISO8583Errors import ...
或者
from ISO8583_Payment.ISOErrors import ...
