Shelve模塊不工作

-1

當我重新安裝Python將其從AppData文件夾移動到Program Files時，看起來擱置模塊不再工作，並且在撥打shelve.open()時收到以下錯誤消息。Shelve模塊不工作

請幫忙！

>>> 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')

「FileNotFoundError：[Errno 2]沒有這樣的文件或目錄：'data.dat'」。擱置模塊工作正常，您只需確保您要閱讀的文件存在。 – Evert

嘗試使用sudo運行python;建議因爲您的錯誤中的權限被拒絕。 – PseudoAj

Evert - shelve.open應該創建該文件，如果它不存在。 –

錯誤「FileNotFoundError：[錯誤2]沒有這樣的文件或目錄：‘data.dat文件’」會告訴你，它無法找到data.dat文件，請檢查文件位置。
