我正在尝试keyring在 jupyter notebook 中使用该模块。

import keyring

keyring.set_password('system',
                    'test',
                    '1234')

我得到以下输出：

如果我直接从 python 控制台或 ipython 控制台运行此代码，它将完美运行。然后，我想这与 jupyter notebook 的某些特殊性有关。我正在使用带有以下软件包的 conda 环境

Name                    Version                   Build  
python                    3.9.5
jupyter                   1.0.0            py39h06a4308_7  
jupyter_client            6.1.12             pyhd3eb1b0_0  
jupyter_console           6.4.0              pyhd3eb1b0_0  
jupyter_core              4.7.1            py39h06a4308_0
keyring                   23.0.1           py39h06a4308_0

操作系统：

最后，我已经能够解决这个问题。jupyter-notebook 的内核有问题。我只是在 conda 环境中安装笔记本。

conda install notebook

我没有意识到 ipython 内核来自基本环境。
