仅在使用python3时实例化Elasticsearch客户端失败

Question

我一直在尝试使用python的elasticsearch库连接到我的ElasticSearch主机。因此，代码如下所示：

client = Elasticsearch(
        ["https://my-machine.io:9200"],
        http_auth=("user", "password")
    )

现在的问题是，该指令仅在我使用python 2.7解释器时有效，而在python 3.6时失败，从而产生以下错误：

File "/usr/local/lib/python3.6/site-packages/elasticsearch/client/__init__.py", line 171, in __init__
    self.transport = transport_class(_normalize_hosts(hosts), **kwargs)
  File "/usr/local/lib/python3.6/site-packages/elasticsearch/transport.py", line 108, in __init__
    self.set_connections(hosts)
  File "/usr/local/lib/python3.6/site-packages/elasticsearch/transport.py", line 163, in set_connections
    connections = list(zip(connections, hosts))
  File "/usr/local/lib/python3.6/site-packages/elasticsearch/transport.py", line 160, in _create_connection
    return self.connection_class(**kwargs)
  File "/usr/local/lib/python3.6/site-packages/elasticsearch/connection/http_urllib3.py", line 78, in __init__
    raise ImproperlyConfigured("Root certificates are missing for certificate "
elasticsearch.exceptions.ImproperlyConfigured: Root certificates are missing for certificate validation. Either pass them in using the ca_certs parameter or install certifi to use it automatically.

Python版本：

$ python2 --version
Python 2.7.13
$ python3 --version
Python 3.6.1

在两种情况下，我都使用版本5.3.0的“ elasticsearch”软件包

我还找不到任何文档，可以根据所使用的python版本建议不同的行为。谁能解释为什么会这样？

看来问题出在您的ssl设定中，请确保您已certifi安装，它将提供所需的根证书。
