Question

已成功安装pip install --upgrade snowflake-connector-python，但是我无法打印雪花版本。不知道可能是什么问题。遵循以下链接中提供的步骤。

https://docs.snowflake.net/manuals/user-guide/python-connector-install.html#step-2-verify-your-installation

import snowflake.connector

    # Gets the version
    ctx = snowflake.connector.connect(
        user='<your_user_name>',
        password='<your_password>',
        account='<your_account_name>'
        )
    cs = ctx.cursor()
    try:
        cs.execute("SELECT current_version()")
        one_row = cs.fetchone()
        print(one_row[0])
    finally:
        cs.close()
    ctx.close()

Traceback (most recent call last):

有人可以帮我吗？

调试network.py后，可以确定在def _request_exec中，在下面的块中执行URL https://account_name.snowflakecomputing.com:443/session/v1/login-request?request_id=9b1c563d-80a2-4608-af4d-8bc6b955ac70&request_guid=b88aba49-384a-409d-8387-4e4f934927ab遇到错误

raw_ret = session.request(

                url=full_url,
                proxies=proxies,

                stream=is_raw_binary,
                auth=SnowflakeAuth(token),
            )

与api / url-execution（requests,urllib3）相关的任何模块都可能有问题，只是一个猜测。谁能帮我吗？

我尝试了代码，对我来说很好用。您是否尝试启用日志记录？如果可以，您可以共享日志吗？另外，请确保您正确设置了帐户详细信息。

只要您没有启用日志记录，就可以通过将以下行添加到python脚本中来启用它：

import logging
logging.basicConfig(
    filename='/tmp/snowflake_python_connector.log',
    level=logging.DEBUG)
