python之Pandas :noauth_local_webserver

我已经有几周没有在 pandas 中使用 io 来访问 google analytic 的 API，但据我所知，它在历史上一直运行良好，没有出现问题。我今天再次运行它，它看起来好像 tools.run 语法已被弃用，所以我做了一个拉动并将 tools.py 替换为 this update我已经将 pandas 中的 auth.py 更改为:

def authenticate(flow, storage=None): 
    """ 
    Try to retrieve a valid set of credentials from the token store if possible 
    Otherwise use the given authentication flow to obtain new credentials 
    and return an authenticated http object 
 
    Parameters 
    ---------- 
    flow : authentication workflow 
    storage: token storage, default None 
    """ 
    http = httplib2.Http() 
 
    # Prepare credentials, and authorize HTTP object with them. 
    credentials = storage.get() 
    if credentials is None or credentials.invalid: 
        credentials = tools.run_flow(flow, storage, FLAGS) 
 
    http = credentials.authorize(http) 
    return http 

我感觉我对 FLAGS 的使用不正确。

有什么帮助吗？谢谢!

这是我的代码和错误:

df = ga.read_ga( 
    account_id  = id, 
    profile_id  = profile, 
    property_id = property, 
    metrics     = ['transactionRevenue', 'transactions'], 
    dimensions  = ['transactionId', 'city', 'region', 'date', 'hour', 'minute', 'cityId'], 
    start_date  = "2015-07-11", 
    end_date    = "2015-07-16", 
    index_col = 0, 
    parse_dates = {'new_date': [3,4,5]}) 

抛出的错误:

请您参考如下方法:

我做了一些挖掘，您认为 FLAGS 的用法不正确的假设是正确的。 docstring for tools.run_flow()状态:

flags: ``argparse.Namespace``, The command-line flags. This is the 
       object returned from calling ``parse_args()`` on 
       ``argparse.ArgumentParser`` as described above. 

快速解决方案应该是这样的:

credentials = tools.run_flow(flow, storage, tools.argparser.parse_args([])) 

我相信如果 tools.run 真的被弃用，pandas.io 的维护者将其更新为新的工作流程是一个更强大的解决方案。
