I am hosting my Web2py app on PythonAnyware and have an issue importing copy_reg which web2py apparently needs. In previous versions this was no issue.

The trace back is as follows: Traceback (most recent call last):

File "/home/richdijk/web2py/gluon/restricted.py", line 220, in restricted
  exec ccode in environment
File "/home/richdijk/web2py/applications/im/models/db.py", line 78, in <module>
  auth.define_tables(username=False, signature=False)
File "/home/richdijk/web2py/gluon/tools.py", line 1784, in define_tables
   format='%(first_name)s %(last_name)s (%(id)s)'))
File "/home/richdijk/web2py/gluon/dal.py", line 8223, in define_table
   table = self.lazy_define_table(tablename,*fields,**args)
File "/home/richdijk/web2py/gluon/dal.py", line 8260, in lazy_define_table
   polymodel=polymodel)
File "/home/richdijk/web2py/gluon/dal.py", line 1122, in create_table
   sql_fields_old = pickle.load(tfile)
File "/home/richdijk/web2py/gluon/custom_import.py", line 92, in custom_importer
  return base_importer(pname, globals, locals, fromlist, level)
ImportError: No module named copy_reg

Does anybody know the resolution for this? Thank you

备查：

大多数情况下，您应该清除缓存和会话。使用 appadmin 界面为此提供一个 gui。这不止一次为我解决了这个问题。

会话是可能导致这些问题的腌制文件。例如，如果您在不同平台、python 版本之间进行同步，有时甚至在 web2py 的升级之间进行同步（尽管我不确定后者）。
