django2.2提示编码出错的解决办法

最新的django2.2版本,操作模板的时候,有可能会提示编码出错。 错误代码:

Traceback (most recent call last):
  File "D:\python\lib\wsgiref\handlers.py", line 137, in run
    self.result = application(self.environ, self.start_response)
  File "D:\python\lib\site-packages\django\contrib\staticfiles\handlers.py", line 65, in __call__
    return self.application(environ, start_response)

    t = DEBUG_ENGINE.from_string(fh.read())

解决办法: 在虚拟环境里这个目录下:venv\Lib\site-packages\django\views* 找到debug.py这个文件 如果没有使用虚拟环境,该文件在Python安装目录里的Lib\site-packages\django\views\里 找到该文件的 331行代码如下:

with Path(CURRENT_DIR, 'templates', 'technical_500.html').open() as fh:

修改成:

with Path(CURRENT_DIR, 'templates', 'technical_500.html').open(encoding='utf-8') as fh:
