谁能帮我安装适用于python的雪花连接器，以便通过python我们可以在雪花中执行查询。

我使用的是 python 版本 3.7.4，以下是我在尝试使用 pip 安装时收到的错误：

【解决方案1】：

错误Connection to pypi.org timed out.，假设您的互联网连接正常，可能表明（除其他可能性外）您正在使用pip 命令未使用的代理，或者存在管理防火墙规则这会阻止您从组织内连接到 Python 包存储库。

如果问题只是代理问题，通过HTTP_PROXY 环境变量在命令提示符中显式try specifying your web proxy URL，然后重试：

(base) C:\Users\a662919> set HTTP_PROXY=http://username:password@your-proxy-host:your-proxy-port

(base) C:\Users\a662919> pip install --upgrade snowflake-connector-python

如果您在指定代理后仍然收到确切的错误，那么您可能遇到了防火墙规则或其他形式的管理块。在这种情况下，联系您的 IT 人员（或同等人员）进行澄清（通过访问 pypi.org）将是一个很好的下一步。

最新版本应该可以解决这个问题。如果可能，也使用虚拟环境。
