我正在尝试使用 Python 连接器和 SSO 连接到 Snowflake。我希望连接器打开浏览器来验证用户身份，但这不起作用：
h:\Code\bin>python conn.py
Initiating login request with your identity provider. A browser window should have opened for you to complete the login. If you can't see it, check existing browser windows, or your OS settings. Press CTRL+C to abort and try again...
浏览器窗口永远不会弹出，而是立即得到以下内容

我可以确认我可以使用 DBD::ODBC 与 Perl 连接，因此外部浏览器验证器原则上可以工作，但我只是不确定为什么它不适用于 Python
