Python：找不到“__main__”模块

Question

我有这个 python 代码，我想从 Windows Run 运行它。但是，当我尝试运行它时，cmd 会显示此消息。

C:\Users\myName\AppData\Local\Programs\Python\Python38-32\python.exe: can't find '__main__' module in 'C:\\Users\\myName\\OneDrive'

我正在使用 VS Code 在 python 3.8.3 32 位虚拟环境中编写我的程序。python程序称为pw.py，批处理文件称为pw.bat

pw.py

C:\Users\myName\OneDrive - 公司名称\04Programming\01 Visual Studio Code\LearningPython\pw.py

#! python3

# pw.py - An insecure password locker program.

import sys, pyperclip

PASSWORD = {'email': 'F7minlBDDuvMJuxESSKHFhTxFtjVB6',

            'blog': 'VmAlvQyKAxiVH5G8vo1if1MLZF3sdt',

            'luggage': '12345'}

if len(sys.argv) < 2:

    print('Usage: python pw.py [account] - copy account password')

    sys.exit()

account = sys.argv[1]   # first commmand line arg is the account name

if account in PASSWORD:

    pyperclip.copy(PASSWORD[account])

    print('Password for ' + account + ' copied to clipboard.')

else:

    print('There is no account named ' + account)

Answer 1

首先，检查一下你是否正确处理空格，这不是那么明显。尝试在批处理文件中添加空格 (  ) 和反斜杠 ( ) 前缀，如下所示：\ @py.exe C:\Users\myName\OneDrive\ -\ companyName\04\ Programming\01\ Visual\ Studio\ Code\LearningPython\pw.py %*@pause另一种方法是将路径用引号引起来，即：@py.exe "C:\Users\myName\OneDrive - companyName\04 Programming\01 Visual Studio Code\LearningPython\pw.py" %*@pause您还可以考虑添加以下内容：if __name__ == "__main__":    #code here使用PASSWORDSdict 之后，即：#! python3# pw.py - An insecure password locker program.import sys, pyperclipPASSWORD = {'email': 'F7minlBDDuvMJuxESSKHFhTxFtjVB6',            'blog': 'VmAlvQyKAxiVH5G8vo1if1MLZF3sdt',            'luggage': '12345'}if __name__ == "__main__":    if len(sys.argv) < 2:        print('Usage: python pw.py [account] - copy account password')        sys.exit()    # And so on...
