Docker

Question

我有文件夹 xyz，其中包含我需要使用 docker 进行 pip 安装的包。通常以下命令有效

pip install xyz/python

我的docker文件如下

FROM python:3.7

RUN mkdir /app
WORKDIR /app
RUN pip install xyz/python/

COPY . .

CMD ["./main.py"]

这是运行 docker-compose up

的最终结果

ERROR: Invalid requirement: 'xyz/python/'
Hint: It looks like a path. File 'xyz/python/' does not exist.
WARNING: You are using pip version 22.0.4; however, version 22.1.1 is available.
You should consider upgrading via the '/usr/local/bin/python -m pip install --upgrade pip' command.

Answer 1

如评论中所述：

你应该把COPY . .放在RUN pip install xyz/python
之前（否则 xyz 文件夹在图像构建期间在 docker 上下文中不可用）
和RUN mkdir /appcan/should也被删除，因为WORKDIR /app本身就是相当于[=23的Dockerfile =]mkdir -p /app && cd /app.
