我尝试搭建环境测试了一下，确实在Python 3.6 下会出现 如上错误，但这个应该是 click 出现了问题。具体的等我详细查看一下的....

[xuxiong]

环境调整为：win10，anaconda2，python2.7， rqalpha-2.1.2
update_bundle正常。

@xuxiong 查看了一下，原因是 colorama 库更新到0.3.8版本，底层覆盖了 sys.stdout .....

其中 ansitowin32.py 文件中定义了如下内容:

class StreamWrapper(object):
    '''
    Wraps a stream (such as stdout), acting as a transparent proxy for all
    attribute access apart from method 'write()', which is delegated to our
    Converter instance.
    '''
    def __init__(self, wrapped, converter):
        # double-underscore everything to prevent clashes with names of
        # attributes on the wrapped stream object.
        self.__wrapped = wrapped
        self.__convertor = converter

    def __getattr__(self, name):
        return getattr(self.__wrapped, name)

    def write(self, text):
        self.__convertor.write(text)

    def fileno():
        raise OSError()

其中 fileno 函数 第一没实现 raise 了一个 OSError 第二 还写错了，少了个self....

从而导致 执行如下命令会报错:

import sys
sys.stdout.fileno()

而... click 包使用了 该函数....

目前 RQAlpha 指定使用 colorama==0.3.6 便可以规避该问题。

您可以指定安装 0.3.6 版本的 colorama 或者稍后更新新版本的RQAlpha 来解决该问题。
