突然關閉后，anaconda-navigator無法運行

Question

我過去幾天一直在運行anaconda-navigator。 我的系統突然關閉了一天。 之后，當我運行anaconda-navigator時，它顯示以下錯誤

dstlab2@dstlab2-Veriton-M200-H81:~$ anaconda-navigator
    Traceback (most recent call last):

        (result, consumed) = self._buffer_decode(data, self.errors, final)
    UnicodeDecodeError: 'utf-8' codec can't decode byte 0xf2 in position 378: invalid continuation byte

誰能幫助我正確設置事情？

好像anaconda導航器使用的配置文件已損壞。 該文件可能存在於$HOME/.anaconda文件夾中。 它的擴展名可能是.ini 。

如果可以識別文件，則可以嘗試替換引起問題的字節（首先制作文件的備份副本）：

>>> with open('config.ini', 'rb+') as f:
...     data = f.read()
...     data = data.replace(b'\xf2', b'')
...     assert data
...     f.seek(0)
...     f.write(data)
... 
0
171

請注意，可能有多個字節。

該文件也可能被截斷或損壞太多，以至於需要將其完全刪除或替換。
