Python 诗歌安装失败 - 无效的哈希值

Question

我不确定这篇文章到底需要提供哪些信息/上下文才能得到正确的回答 - 因此，如果我可以添加更多信息，请告诉我。

\n

在尝试安装软件包时，我收到一条错误消息，如下所示：

\n

  Invalid hashes (sha256:01d6b62184e55367ce7d770bd87d97a6cfaf783ff7ba8328e7473a339fe19807) for numpy (1.22.2)\n

\n

我不知道如何解决这个问题。

\n

输出poetry env info：

重现步骤

\n

以下是清晰地概述此问题的再现的尝试：

\n

  Invalid hashes (sha256:01d6b62184e55367ce7d770bd87d97a6cfaf783ff7ba8328e7473a339fe19807) for numpy (1.22.2)\n

接下来，在离开并重新访问目录以激活环境后，我有：

\n

尝试解决

\n

删除现有的诗歌装置

\n

curl -sSL https://install.python-poetry.org | python3 - --uninstall\n

\n

安装特定的诗歌版本

\n

尝试遵循我安装的这个问题评论：

\n

curl -sSL https://install.python-poetry.org | python3 - --version 1.1.8\n

\n

尝试像以前一样创建另一个环境（仍然失败）

\n

我仍然遇到失败。

\n

\n

然后在新创建的项目中：

Answer 1

有几个 问题 报告。一个常见的原因是同时运行多个 Poetry 实例；另一个是中止下载（例如^C）。应该修复诗歌，以减少在这种情况下发生损坏的可能性，并且也许可以尝试自动再次下载损坏的文件。

在此之前，解决方法是从缓存中删除有问题的文件，并让 Poetry 下载新的副本。

您可以像这样找到有问题的文件的完整路径：

$ find ~/.cache/pypoetry -name numpy-1.22.2-cp38-cp38-macosx_10_14_x86_64.whl

或者，对于懒人来说，只需清除整个缓存即可：

$ rm -rf ~/.cache/pypoetry

Answer 2

我ctrl-C在 a 期间poetry install，导致其中一个缓存的轮子部分下载，并且哈希值与 PyPI 上的内容不匹配。

在装有 Poetry 1.1.13 的 macOS 上，唯一对我有用的方法是Yihua Zhou 的评论：

rm -r ~/Library/Caches/pypoetry/cache
rm -r ~/Library/Caches/pypoetry/artifacts

Answer 3

也许这是一个解决方案：

poetry cache clear . --all
rm poetry.lock
poetry install

Answer 4

如果您在 Docker 映像中执行此操作，除了上面的答案之外，我还必须执行以下操作：

docker builder prune

如果在 Dockerfile 中使用一些最新的 docker 构建缓存功能，这可能是必要的，例如：

RUN --mount=type=cache,target=$POETRY_CACHE_DIR/cache \
    --mount=type=cache,target=$POETRY_CACHE_DIR/artifacts \
    poetry install

这是因为诗歌缓存位于主机文件系统上，需要清除，原因与上述答案相同。
