Python3.7&Django1.11.15 兼容性问题
环境:
1. Windows10
2. python3.7
3. Django1.11.15
启动Django时抛出以下异常:
Unhandled exception in thread started by <function check_errors.<locals>.wrapper at 0x0000024D934BDD08>

'%s=%s' % (k, v) for k, v in params.items(),
^
SyntaxError: Generator expression must be parenthesized
解决方法:
把“'%s=%s' % (k, v) for k, v in params.items(),”中的后边的逗号去掉就ok了
linux下的解决:
Linux下启动失败跑抛出异常,和Windows下一样,查看抛出异常的最后一个提示的路径和行号。使用sudo编进该路径下的该py文件,方法同上,保存就ok了
类似的文件路径:
sudo vi /usr/local/lib/python3.7/site-packages/django/contrib/admin/widgets.p
related_url += '?' + '&'.join(
'%s=%s' % (k, v) for k, v in params.items(),
)
修改:
related_url += '?' + '&'.join(
'%s=%s' % (k, v) for k, v in params.items()
)
