当我尝试在 tornado 包中运行“博客”演示时。我遇到以下问题:
Traceback (most recent call last):
File "./blog.py", line 196, in <module>
main()
File "./blog.py", line 190, in main
http_server = tornado.httpserver.HTTPServer(Application())
File "./blog.py", line 63, in __init__
user=options.mysql_user, password=options.mysql_password)
File "/usr/local/lib/python2.7/dist-packages/tornado/database.py", line 58, in __init__
args = dict(conv=CONVERSIONS, use_unicode=True, charset="utf8",
NameError: global name 'CONVERSIONS' is not defined
谢谢你的帮助。
