Pyinstaller: IndexError: tuple index out of range

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_bytes
    argval, argrepr = _get_const_info(arg, constants)
  File "C:\Program Files\Python\lib\dis.py", line 292, in _get_const_info
    argval = 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 = 0
    for i in range(0, len(code), 2):
        op = code[i]
        if op >= HAVE_ARGUMENT:
            arg = code[i+1] | extended_arg
            extended_arg = (arg << 8) if op == EXTENDED_ARG else 0
        else:
            arg = None
            extended_arg = 0  # +
        yield (i, op, arg)
