spyder unicode decode error in startup

问题

I was using spyder-ide while parsing a tumblr page with the permission of the author, and at some point everything just crashed. Even my linux system had freezed. Well, to cut to the chase now I can not start spyder, it gives me the following error after I had written spyder to my terminal:

 Traceback (most recent call last):
  File "/home/dk/anaconda3/bin/spyder", line 2, in <module>
    from spyderlib import start_app
  File "/home/dk/anaconda3/lib/python3.5/site-packages/spyderlib/start_app.py", line 13, in <module>

    self._read(fp, filename)

    for lineno, line in enumerate(fp, start=1):
  File "/home/dk/anaconda3/lib/python3.5/codecs.py", line 321, in decode
    (result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode bytes in position 0-1: invalid continuation byte

I tried the solution here and I had received the following error:

Traceback (most recent call last):

UnicodeDecodeError: 'utf-8' codec can't decode bytes in position 0-1: invalid continuation byte

I tried uninstalling and reinstalling anaconda and it doesn't seem to work I am open to suggestions, I am very much new to python, so I would appriciate a simple explanation of the possible causes of the error too.

Thanks in advance

回答1:

Well here is how I solved the issue.
l opened this: spyderlib/userconfig.py
and changed this: self.read(self.filename(), encoding='utf-8')
to this: self.read(self.filename(), encoding='latin-1')
It gave me a Warning: File contains no section headers but started spyder anyway. After that, I closed spyder, opened the terminal and entered spyder --reset then restarted spyder, it seems to work now.
Here is what you should not do at all costs for this problem: thinkering with these, I learned my lesson the hard way:

python3.5/configparser.py
python3.5/codecs.py
