ValueError：在 Docker 映像中安装 Python 包时，“Requirement”对象没有字段“use_pep517”

Question

我在 Dockerfile 中使用 pipelinenv 安装 Python 依赖项时遇到问题。

Dockerfile：

RUN pip install --upgrade pip
RUN pip install pipenv

# Copy dependencies source code
WORKDIR /projects

# Copy project source code
WORKDIR /projects/source
COPY ./projects/source .

# Install packages
RUN pipenv install --system --deploy

我们使用以下 pipelinev 依赖项成功构建了映像：

# Result of pip install pipenv
Successfully installed certifi-2023.5.7 distlib-0.3.6 filelock-3.12.2 pipenv-2023.7.11 platformdirs-3.9.1 setuptools-68.0.0 virtualenv-20.24.0 virtualenv-clone-0.5.7

pipenv install --system --deploy但现在，当我们在 Docker 映像中执行以下操作时，我们遇到了此错误：

# Result when executing pipenv install --system --deploy

ValueError: "Requirement" object has no field "use_pep517"

当 Docker 尝试安装 pipelinev 时，我确实注意到distlib版本略有变化，但不确定这是否是问题所在

Successfully installed certifi-2023.5.7 distlib-0.3.7 filelock-3.12.2 pipenv-2023.7.11 platformdirs-3.9.1 setuptools-68.0.0 virtualenv-20.24.0 virtualenv-clone-0.5.7

我尝试升级本地 pipelinenv 并重建 Pipfile.lock，但当我尝试在 Docker 映像中构建它时，它仍然给出相同的错误。

我在 Docker 中构建的几个 Python 项目也遇到了同样的问题。看起来这是 PyYAML 的问题。这是我看到修复的另一篇文章：

Docker-compose 不再构建映像（AttributeError：cython_sources）

我针对不同的项目采用了两种不同的解决方法。在一个项目中，我刚刚升级了所有可以再次运行的软件包。在另一个项目中，我最终不得不切换回 PyYAML 5.3.1。这些项目只是内部的，所以我不太担心安全性。

需要注意的一件事是，尝试使用 pip 而不是 pipenv 安装失败的特定包（我一一尝试，直到找到罪魁祸首）将产生更具体的错误消息，从而引导我找到链接的答案。

希望这可以帮助！
