Question

我在Ubuntu中收到此web2py错误：

Traceback (most recent call last):
  File "/home/mwk/web2py/gluon/restricted.py", line 227, in restricted
    exec ccode in environment
  File "/home/mwk/web2py/applications/britamintell/models/db2.py", line 15, in <module>

    sql_fields_old = pickle.load(tfile)
UnpicklingError: invalid load key, '�'.

这是什么以及如何解决？

没有太多关于您尝试做什么的信息。但是，我想你正在尝试迁移数据库。如果您使用MYSQL作为您的BBDD后端，您可以尝试将长度更改为＆＃34; length = 255＆＃34;在你的字符串字段上。

似乎在表/字段名称中使用了一个奇怪的字符
