有没有人有一些想法可以解释这个奇怪的问题？感谢您的时间和考虑。
答案 0 :(得分：0)
您应该同时拥有sqlall和sql管理命令。两者都存在于1.0 it appears
$ ./manage.py help sqlall
...
Usage: manage.py sqlall [options] <appname appname ...>
Prints the CREATE TABLE, custom SQL and CREATE INDEX SQL statements
for the given model module name(s).
...
查看其中包含sql的命令：
$ ./manage.py --help | grep sql
monitor (pid=16660): Starting change monitor.
sql
sqlall
sqlclear
sqlcustom
sqlflush
sqlindexes
sqlinitialdata
sqlreset
sqlsequencereset
sqlcreate
sqldiff
$ ./manage.py shell

正如评论中所指出的，你有一个KeyError：
File "/Users/levicc00123/DoneBox/DoneBox/settings.py", line 16, in <module>
'NAME': os.environ['RDS_DB_NAME'],
File "/Users/levicc00123/DoneBox/env/lib64/python2.6/UserDict.py", line 22, in __getitem__
raise KeyError(key)
要解决此问题，您可以使用get的{{1}}方法并提供默认值。例如：
os.environ
