Docker 安装 Poetry 失败

Question

我有一个 Django 项目，我正在尝试使用 Docker 对其进行设置。我用的是Poetry，所以我要在容器里安装Poetry。下面是我的 Dockerfile.

FROM python:3.9.7-alpine
WORKDIR /usr/src/app

ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1

# install curl because it does not exist on alpine
RUN apk --no-cache add curl

# install poetry
RUN curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/install-poetry.py | python -

# install dependencies
RUN poetry install

COPY . .

然而，它给出了这个毫无帮助的晦涩错误：

Traceback (most recent call last):
  File "<stdin>", line 440, in run
  File "<stdin>", line 464, in install
  File "<stdin>", line 589, in install_poetry
  File "/usr/local/lib/python3.9/subprocess.py", line 528, in run
    raise CalledProcessError(retcode, process.args,
subprocess.CalledProcessError: Command '['/root/.local/share/pypoetry/venv/bin/python', '-m', 'pip', 'install', 'poetry==1.1.8']' returned non-zero exit status 1.

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<stdin>", line 837, in <module>
  File "<stdin>", line 833, in main
  File "<stdin>", line 443, in run
AttributeError: 'NoneType' object has no attribute 'decode'
The command '/bin/sh -c curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/install-poetry.py | python -' returned a non-zero code: 1

没有发现任何与此相关的问题或帖子，所以我想问问是否有人遇到过这个问题或有人知道如何解决这个问题。

提前致谢。

不幸的是，安装程序脚本隐藏了原始错误消息。否则可以看到，由于缺少 compiler.Install docs 中列出的包，无法构建加密包 (gcc musl-dev python3-dev libffi-dev openssl-dev货物），它应该可以工作。
