Poetry 更新失败：无法找到 pyqt5-qt5 （5.15.11） 的候选安装对象
Poetry Update Fails: Unable to Find Installation Candidates for pyqt5-qt5 (5.15.11)
问：
我的环境：
- 操作系统： [Windows 22H2]
- Python版本：[3.11]
- 诗歌版本：[（version 1.7.1）]
尝试的解决方案：
- 清除 Poetry 的缓存
- 直接指定了不同版本的中。
pyqt5-qt5pyproject.toml - 检查网络设置和代理配置
问题描述：
我在尝试使用 Poetry 更新我的 Python 项目依赖项时遇到了一个问题。具体来说，Poetry 无法找到版本 5.15.11 的安装候选者。以下是我尝试过但未解决问题的步骤：pyqt5-qt5
- 清除了 Poetry 的缓存
- 已确认我的网络连接稳定
- 尝试指定不同版本的
pyqt5-qt5
这是我运行时的输出：poetry update

相反，当我通过pip安装pyqt5时，这是正常的：

诗歌的错误没有改变。
此外，运行还会导致错误：pip wheel --no-cache-dir --use-pep517 "pyqt5 (==5.15.1)"
$ pip wheel --no-cache-dir --use-pep517 "pyqt5 (==5.15.1)"

当然，我试过使用
$poetry cache clear --all pypl
但它不起作用。
安装后，我更新如下，但问题仍然存在：pippyproject.toml
pyqt5 = "=5.15.10"

问题摘要：
目前，我能够使用 成功安装，但是在尝试通过 配置时遇到了问题。这让我思考这个问题的根本原因是否在于我的特定配置、我使用的 Python 版本，还是我可能不知道的设置的某些未知方面。我正在寻找见解或解决方案，以有效解决 和 之间的这种差异。pyqt5pippoetrypoetrypippoetry
其他上下文：
pip install pyqt5工作没有任何问题。poetry add pyqt5或导致错误，特别是在查找安装候选项或为 .poetry updatepyqt5- 我的环境使用Python 3.11，我尝试过清除缓存并直接在中指定版本。
poetrypyproject.toml - 无论 中指定的版本如何，该问题仍然存在。
pyqt5pyproject.toml
我已经检查了相关文档和其他类似问题，但没有找到解决方案。
有没有人遇到过类似的问题，或者有人对如何解决它有任何建议？
谢谢！
我试过什么：
使用 pip：我使用 pip 成功安装了 pyqt5，没有遇到任何问题。
使用诗歌：
我尝试使用诗歌添加 pyqt5 添加 pyqt5，这导致了与查找安装候选者相关的错误。 运行诗歌更新也导致了类似的问题，特别是为 pyqt5 构建轮子时的错误。 我尝试在pyproject.toml中指定不同版本的pyqt5，但问题仍然存在。 其他尝试：
使用 poetry cache clear --all pypi 清除了 Poetry 的缓存。 已检查并确认网络设置和代理配置。 我期待什么：
我期待诗歌能像 pip 一样顺利地处理 pyqt5 的安装。具体来说，我预计诗歌添加或诗歌更新将成功解决和安装 pyqt5 依赖项而不会遇到错误，特别是因为通过 pip 安装是成功且直接的。
