使用Python3.10时，Pyinstaller出现IndexError: tuple index out of range错误，部分异常信息如下：

.......yield from get_instructions(code_object)File "C:\Program Files\Python\lib\dis.py", line 338, in _get_instructions_bytesargval, argrepr = _get_const_info(arg, constants)File "C:\Program Files\Python\lib\dis.py", line 292, in _get_const_infoargval = const_list[const_index]
IndexError: tuple index out of range

解决办法

修改C:\Program Files\Python\lib\dis.py文件，找到_unpack_opargs函数，在倒数第二行中添加extended_arg = 0 即可，修改后的代码如下：

def _unpack_opargs(code):extended_arg = 0for i in range(0, len(code), 2):op = code[i]if op >= HAVE_ARGUMENT:arg = code[i+1] | extended_argextended_arg = (arg << 8) if op == EXTENDED_ARG else 0else:arg = Noneextended_arg = 0  # +yield (i, op, arg)

亲测有效
