Question

最新的雪花连接器似乎存在一些问题。我正在尝试在Ubuntu OS上安装它，并尝试连接到雪花，但是它给出了错误AttributeError：'SSLSocket'对象没有属性'connection'

以下是环境详细信息：-

我正在使用python3.5.2版本的ubuntu（Ubuntu 16.04.6 LTS），并且还安装了最新的雪花python连接器2.2.6。

我正在使用雪花文档中提到的示例python代码 https://docs.snowflake.com/en/user-guide/python-connector-install.html#step-2-verify-your-installation

这是错误：-

Answer 1

您可以运行以下命令来更新请求，然后尝试

pip3安装请求== 2.23.0

还请尽可能将Python版本升级到3.7，并检查问题是否仍然存在。
