进行 betfair.py API 调用时出现类型错误
Type error making a betfair.py API call
我刚刚将一些代码移到了 Ubuntu 16.04.2 anaconda 设置中，并且在调用在许多其他机器上运行良好的代码时遇到了我不理解的类型错误。
错误为我复制了下面回购协议中所有网球市场示例代码的列表，以及如下请求：
from betfair import Betfair
client = Betfair("app key needed here", "path to ssh key here")
client.login(username, password)
client.keep_alive()
client.list_market_book(market_ids=['1.135391020'], price_projection=dict(priceData=['EX_BEST_OFFERS']))
或
from betfair.models import MarketFilter
event_types = client.list_event_types(
MarketFilter(text_query='tennis')
)
print(len(event_types)) # 2
print(event_types[0].event_type.name) # 'Tennis'
tennis_event_type = event_types[0]
markets = client.list_market_catalogue(
MarketFilter(event_type_ids=[tennis_event_type.event_type.id])
)
markets[0].market_name
尽管相同的代码在 windows 安装上工作，但两者都抛出以下类型错误：

从轨迹上看，原理图库似乎是您的问题。检查 open issues on the betfair github there is, as of this writing, an open ticket regarding schematics breaking the api。看起来作者将原理图排除在要求之外，而版本 1.1.1 是必需的。我猜你的电脑上安装了 schematics 2.0 导致了这个问题。
将来找到它的一种方法是 pip freeze 工作环境并区分损坏的环境。此外，当移动到新机器时，您可以使用 pip freeze 的输出来复制环境并避免像这样混乱的版本问题。
