有人可以帮我安装用于Python的Snowflake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 3.7.4版本，以下是我尝试使用pip安装时收到的错误：

错误Connection to pypi.org timed out.（假设您的Internet连接正常运行），可能（除其他可能性外）指示您正在使用pip命令未使用的代理，或管理防火墙规则已到位，可防止您从组织内部与Python软件包存储库建立连接。
如果问题仅是代理的问题，请通过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
如果尽管指定了代理仍然继续收到确切的错误，则可能是您遇到了防火墙规则或其他形式的管理块。在这种情况下，与您的IT人员（或类似人员）联系以进行澄清（通过访问pypi.org）将是一个不错的下一步。

最新版本应该可以解决此问题。如果可能，还请使用虚拟环境。
