在运行poetry install时出现了DBusErrorResponse。

Question

我尝试将我的诗歌从1.1.x版本升级到1.3版本，但正如官方手册（https://python-poetry.org/docs/）建议的那样，我手动删除了旧版本。不幸的是，我可能删除了错误的文件，因为在安装1.3版本后，我仍然收到错误提示，似乎与旧诗歌有冲突。

我尝试使用find /home/username -name *poetry*查找与诗歌相关的所有文件（这是一个远程机器，所以我不想影响其他人），并在卸载诗歌1.3后将它们删除。然后我重新安装了诗歌1.3，但仍然无法正常工作。

我还尝试删除整个存储库并再次克隆它，但问题仍然存在。我想我已经搞砸了，但希望有一些方法可以进行硬重置。有没有办法解决这个问题？

以下是我的错误消息开头：

你可能会在这个答案中找到一些线索：https://dev59.com/x1EG5IYBdhLWcg3wOXOV#70064450。 - Mikko Ohtamaa

我尝试了你们所有的建议，但不幸的是都没有帮助。 - Emil Haas

你知道什么是secretstorage以及为什么在运行Poetry时系统会尝试使用它吗？ - Mikko Ohtamaa

因为这不是标准诗歌流程的一部分，而且这是我第一次看到它。 - Mikko Ohtamaa

我之前不知道secretstorage，但它似乎是一些辅助包。但我不确定它是为哪个包而需要的，而且在我的poetry.lock文件中也没有指定（当我在另一台之前未安装过poetry 1.1的电脑上尝试时，这不是问题）。 - Emil Haas

我编辑了我的错误信息 - 我将其开头添加到了问题中。实际上，我发现有人在这里遇到了相同的错误（https://github.com/python-poetry/poetry/issues/6558），但他只是被引用到了这里（https://github.com/python-poetry/poetry/issues/1917）。有一些提示可以设置PYTHON_KEYRING_BACKEND=keyring.backends.null.Keyring，但我不知道在哪里设置，也无法在那里询问。我尝试将其添加到某些配置文件中，但要么那不是我的情况，要么我使用了错误的配置... - Emil Haas

Answer 1

最终我在这里找到了答案。

有几种方法可以实现：

1. 在shell中运行export PYTHON_KEYRING_BACKEND=keyring.backends.null.Keyring，可在关闭（退出）shell会话之前的poetry命令中使用

2. 为每个！poetry命令添加环境变量，例如PYTHON_KEYRING_BACKEND=keyring.backends.null.Keyring poetry install

3. 如果您想在shell会话或系统重新启动之间保留（存储）此环境变量，则可以将其添加到.bashrc和.profile中 bash shell示例：

   echo 'export PYTHON_KEYRING_BACKEND=keyring.backends.null.Keyring' >> ~/.bashrc

   echo 'export PYTHON_KEYRING_BACKEND=keyring.backends.null.Keyring' >> ~/.profile exec "$SHELL"

对于第3种情况，您现在可以像往常一样运行任何poetry命令，即使在系统重新启动后也是如此。
