使用在Python 3.9.7上运行的Jupyter，我无法使用snowflake.connector.connect创建与snowflake的连接。该单元将运行约 2 分钟并抛出错误，提示
MethodNotAllowed: 000405: HTTP 405: Method not allowed我在网上看到可能是我的python路径没有设置。我可以看到 Snowflake.connector 安装在
'C:\Users\{user}\AppData\Roaming\Python\Python39\site-packages\snowflake\connector' C:\Users\{user}\AppData\Local\Programs\Python\Launcher\%USERPROFILE%\AppData\Local\Microsoft\WindowsApps以上两个路径指向我之前安装的Python 3.11，但无法在VSCode中使用Jupyter连接，所以我保留了3.9版本。虽然我安装的其他可以工作的软件包也位于
C:\Users\{user}\AppData\Roaming\Python\Python39\site-packages\整天四处寻找以解决此问题，但无法解决。我收到的错误如下，了解更多信息。
我是设置 Python 环境的初学者，因此欢迎您提供任何进一步的建议。谢谢
