apk：未找到，即使使用 python:3.9-alpine

Question

我正在尝试构建 docker 图片：

FROM python:3.9-alpine

ENV PYTHONDONTWRITEBYTECODE=1
ENV PYTHONUNBUFFERED=1
...

但是，我得到了这个错误：

据我所知，最常见的问题是使用非 Alpine 图像并尝试访问 apk 管理器。但是，我不明白，我的怎么了。

Answer 1

我相信您必须在 docker 文件中添加运行时依赖项。尝试在您的 docker 文件

中添加此命令

FROM python:3.9-alpine

# ensure local python is preferred over distribution python
ENV PATH /usr/local/bin:$PATH

#add runtime dependencies
RUN apk add --no-cache

ENV PYTHONDONTWRITEBYTECODE=1
ENV PYTHONUNBUFFERED=1

Answer 2

错误在这里

ENV PATH="/scripts:{PATH}"

改为

ENV PATH="/scripts:${PATH}"

你错过了一个$

apk：未找到，即使使用 python:3.9-alpine

apk: not found, even with python:3.9-alpine

python

linux

docker

docker-compose

alpine
