当我在项目上将python从2.7.16更新到3.7.4时，django控制台显示如下记录错误：
--- 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'
但是当我使用python2.7时，效果很好
我的环境：Windows 10 python3.7.4 django2.2.5 eclipse + pydev7.3.0.201908161924 有关记录部分的django settings.py

我可以看到Django请求日志已记录在skstack-info.log中

/skworkorders/WorkOrderCommit/ HTTP/1.1" 200 35764
当我在发射中修改文件“ c：\ python37 \ Lib \ logging__init __。py”，行1029时
stream.write(msg + self.terminator)
到
stream.write(str.encode(msg + self.terminator))
它还向我显示了另一个错误，如下所示：
--- 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
答案 0 :(得分：0)
当我无法像下面那样登录logging.loggers.django时，它工作正常，但我在IDE控制台上再也看不到django日志了
'loggers': {
# 'django': {
# 'handlers': ['console'],
# 'propagate': True,
# },
答案 1 :(得分：0)
我通过以下方法解决了这个问题
1。我使用“ logging”作为关键字搜索我的代码，发现我已经在另一个地方设置了logging.basicConfig
2.我将文件模式从filemode ='ab +'更改为filemode ='a +'然后工作正常
3.完整的设置如下
AfterConstruction答案 2 :(得分：0)
为避免该错误，正如您提到的那样，足以使用
filemode='a+'
我正在使用bw，并更改为a +后，它立即开始在Python3.7上运行。
希望可以提供更多帮助。 谢谢并恭祝安康， 马可
