how to used the api

[leeyisoft]

run after ok, how to used the api?
I tried and failed :
3> simple_cache:insert(lee, "leeyi").
...
4> simple_cache:insert(lee, leeyi).
...
5> simple_cache:insert(lee, 33).
...
6> simple_cache:insert(lee, [leeyi,dd]).
...
9> simple_cache:insert('lee', 'dd').
** exception error: bad argument
in function ets:lookup/2
called as ets:lookup(sc_store,lee)
in call from sc_store:lookup/1 (src/sc_store.erl, line 17)
in call from simple_cache:insert/2 (src/simple_cache.erl, line 8)

It's hard to say from your examples, but something has probably crashed between line 6 and line 9, so that the ets table is no longer available. Can you repeat the failure?

I know the problem:
must be executed sc_stoce:init();
