在 python 之后import z3，我做了x = Int('x'). 这给了我回溯

In [16]: x = Int('x')
---------------------------------------------------------------------------
ArgumentError                             Traceback (most recent call last)

   1255   err = lib().Z3_get_error_code(a0)
   1256   if err != Z3_OK:

ArgumentError: argument 2: <type 'exceptions.TypeError'>: unbound method from_param() must be called with Ast instance as first argument (got int instance instead)

我用pip install angr-z3. 怎么了？
