Question

当我尝试构建图像时：

Traceback (most recent call last):
  File "/usr/local/bin/pip3", line 5, in <module>
    from pip._internal.cli.main import main
ModuleNotFoundError: No module named 'pip._internal.cli.main'

这是我的 dockerfile：

FROM python:3.8-slim-buster
WORKDIR /app
COPY requirements.txt requirements.txt
RUN pip3 install -r requirements.txt

RUN pip install python3-wkhtmltopdf
RUN apt-get update
RUN apt-get install -y wkhtmltopdf
COPY . .
CMD [ "python3", "app.py"]

我在这里遗漏了什么？

Answer 1

看起来您实际上是在尝试安装 py3-wkhtmltopdf。为此，您只需利用 python -m pip 并直接安装软件包：

FROM python:3.8-slim-buster
WORKDIR /app

# following their linux installation instructions
RUN apt-get update && apt-get install -y \
  xvfb \
  xfonts-100dpi xfonts-75dpi xfonts-scalable xfonts-cyrillic \
  wkhtmltopdf

COPY requirements.txt requirements.txt
RUN python -m pip install -r requirements.txt
COPY . .
CMD [ "python", "app.py"]

其中 requirements.txt 可能看起来像：

py3-wkhtmltopdf

在构建 Docker 映像时安装 wkhtmltopdf 时找不到 Pip 错误
