为什么相同的IDApython反编译脚本在命令行和IDA UI之间得到不同的结果？

Question

我在IDApython脚本中使用idaapi.decompile()来获取当前函数的伪代码。它确实在IDA Pro的脚本命令中起作用。

这是我的代码：

def get_pseudocode(ea):
    """
    get function's pseudocode
    Args:
        ea: functions's start address
    Returns:
        pse_str: pseudocode
    """
    print("ea: ", ea)
    f = idaapi.get_func(ea)
    print("f: ", f)
    print("f bb_num: ", len(list(idaapi.FlowChart(f))))
    if f is None:
        print("Function is None!")
        return False

    cfunc = idaapi.decompile(f)
    if cfunc is None:
        print("Failed to decompile!")
        return False

    pse_str_list = []

    pse_code = cfunc.get_pseudocode()
    for each_line in pse_code:
        line = idaapi.tag_remove(each_line.line)
        pse_str_list.append(line)

    pse_str = "\n".join(pse_str_list)

    return pse_str

但是，当我尝试从命令行运行脚本时：

D://ProgramFiles/IDA/ida64.exe -LD:/mylog.log -c -A -SD://funcpesudo/getPseudocode.py D://transfer/m64-O0/aes-x86_64.o

我收到此错误：

('ea: ', 0L)
('f: ', <ida_funcs.func_t; proxy of <Swig Object of type 'func_t *' at 0x000000E74712E2A0> >)
('f bb_num: ', 3)
Hex-Rays Decompiler got called from Python without being loaded -> OK

    pse_code = get_pseudocode(func)  # 伪代码
  File "D://funcpesudo/getPseudocode.py", line 36, in get_pseudocode
    cfunc = idaapi.decompile(f)
  File "D:\ProgramFiles\IDA\python\ida_hexrays.py", line 8852, in decompile
    raise DecompilationFailure(hf)
DecompilationFailure: Decompilation failed: 

因此，我认为函数f中的函数对象get_pseudocode是正确的，而我只是不知道为什么会发生此错误。

有人可以帮助我吗？非常感谢。英语不是我的母语。请原谅输入错误。
