@[TOC](Django运行runserver报Error t = DEBUG_ENGINE.from_string(fh.read()) UnicodeDecodeError: ‘gbk’ codec can’t dec)
环境：windows10 & python3.7 & django2.2
发现：在运行Django项目时，经常性的报出如下错误：

UnicodeDecodeError: 'gbk' codec can't decode byte 0xa6 in position 9737: illegal multibyte sequence
查看错误最后一行发现是 ‘gbk’ 编码错误
找到 Django 源码 “Python安装路径（或者是虚拟环境路径）\lib\site-packages\django\views\debug.py” 332行位置，增加 utf-8 编码，问题解决
def get_traceback_html(self):
"""Return HTML version of debug 500 HTTP error page."""
with Path(CURRENT_DIR, 'templates', 'technical_500.html').open( encoding='utf-8' ) as fh:
t = DEBUG_ENGINE.from_string(fh.read())
c = Context(self.get_traceback_data(), use_l10n=False)
return t.render(c)
