Logging error

[encodingl]

when I updated the python from 2.7.16 to 3.7.4 on my project,the django console show logging error as follows:

--- Logging error ---
Traceback (most recent call last):
  File "c:\python37\Lib\logging\__init__.py", line 1028, in emit
    stream.write(msg + self.terminator)
TypeError: a bytes-like object is required, not 'str'

But It works fine when i used python2.7

My Env:windows 10 python3.7.4 django2.2.5 eclipse+pydev7.3.0.201908161924
the django settings.py about the logging part

I can see that the django request log has been recorded in skstack-info.log

I tried the following, but it didn't work:

1. reinstall the python virtual machine environment;
2. use django 1.11.x version;

[encodingl]

when i modify File "c:\python37\Lib\logging_init_.py", line 1029, in emit

stream.write(msg + self.terminator)

to

stream.write(str.encode(msg + self.terminator))

it also show me the another error as following:

--- Logging error ---
Traceback (most recent call last):
  File "c:\python37\Lib\logging\__init__.py", line 1029, in emit
    stream.write(str.encode(msg + self.terminator))
TypeError: write() argument must be str, not bytes

Hi. Sorry, this isn't the right place for support issues.

I'd normally suggest django-users, but this particular question looks perfect for Stack Overflow. Be sure to include your full traceback and if you can, the values at the call site. (It's worth searching too: these Py2 to Py3 issues have come up many times.)

Sorry I can't help you here. Good luck!
