macOS 10.12.3 python 2.7.13 requests 2.13.0
我使用请求包发送发布请求。此请求需要在发布数据之前登录。所以我使用 request.Session() 并加载登录的 cookie。然后我使用这个会话以循环模式发送帖子数据。
我曾经在 Windows 和 Linux 中运行此代码并没有错误。
简单代码：

s = request.Session()
s.cookies = cookieslib.LWPCookieJar('cookise')
s.cookies.load(ignore_discard=True)
for user_id in range(100,200):
    url = 'http://xxxx'
    data = { 'user': user_id, 'content': '123'}
    r = s.post(url, data)
    ...

但是程序经常（大约每个间隔）崩溃，错误是AttributeError: 'module' object has no attribute 'kqueue'

如果您使用类似eventletor的东西，这看起来像是一个通常会出现的问题gevent，两者都对select模块进行了猴子补丁。如果您使用它们来实现异步，则需要确保在导入请求之前应用了这些猴子补丁。这是一个已知的错误，在这个问题中被跟踪。
