    这是一个创建于 856 天前的主题,其中的信息可能已经有所发展或是发生改变。
    用的是 py2.7,pip 版本 19.2.3, 使用命令
    pip install pyinstaller
    报错如下:

    The NullHandler is only available on Python version 2.7+. You could create the NullHandler yourself on an ImportError:

    import logging

    try:
    from logging import NullHandler
    except ImportError:
    class NullHandler(logging.Handler):
    def emit(self, record):
    pass

    logging.getLogger(__name__).addHandler(NullHandler())
