Question

我重新安装Python后将其从AppData文件夹移动到Program Files，看起来搁置模块不再有效，我在调用shelve.open()时收到以下错误。

请帮忙！

 >>> import shelve
    >>> myShelf = shelve.open('data')
    Traceback (most recent call last):
      File "C:\Program Files\Python\lib\dbm\dumb.py", line 81, in _create
        f = _io.open(self._datfile, 'r', encoding="Latin-1")
    FileNotFoundError: [Errno 2] No such file or directory: 'data.dat'

    During handling of the above exception, another exception occurred:

    Traceback (most recent call last):
      File "<pyshell#1>", line 1, in <module>
        myShelf = shelve.open('data')
      File "C:\Program Files\Python\lib\shelve.py", line 243, in open
        return DbfilenameShelf(filename, flag, protocol, writeback)
      File "C:\Program Files\Python\lib\shelve.py", line 227, in __init__
        Shelf.__init__(self, dbm.open(filename, flag), protocol, writeback)
      File "C:\Program Files\Python\lib\dbm\__init__.py", line 94, in open
        return mod.open(file, flag, mode)
      File "C:\Program Files\Python\lib\dbm\dumb.py", line 303, in open
        return _Database(file, mode, flag=flag)
      File "C:\Program Files\Python\lib\dbm\dumb.py", line 69, in __init__
        self._create(flag)
      File "C:\Program Files\Python\lib\dbm\dumb.py", line 83, in _create
        with _io.open(self._datfile, 'w', encoding="Latin-1") as f:
    PermissionError: [Errno 13] Permission denied: 'data.dat'
    >>>

Answer 1

错误“FileNotFoundError：[Errno 2]没有这样的文件或目录：'data.dat'”显示你，它找不到data.dat，请检查文件位置。

Answer 2

我在Windows 10上遇到了这个问题。我通过将工作目录更改为个人资料下的文件夹来解决了这个问题。

os.chdir('C:\\Users\\Nat\\Documents\\Python\\Project 1')

我想我没有写文件“ Program Files”的权限。

搁架模块不工作
