SyntaxError: Generator expression must be parenthesized

理由:
django 1.11バージョンとpython 3のためかもしれません.7バージョンは互換性がありません.次のバージョンでこの問題が修正されたようです.
解決方法:

File "D:\lijingwen\Python\Python37\lib\site-packages\django\contrib\admin\widgets.py", line 152
    '%s=%s' % (k, v) for k, v in params.items(),

彼はこのwidgets.pyファイルが間違っていて、上の.items(),という後ろのカンマを消せばいいと言っています.django 2.0以上のバージョンにアップグレードすればいいのではないでしょうか.
