E：無法在多階段Docker構建中找到軟件包

Question

當我僅構建主映像時，將替換所有軟件包。 但是，一旦我將其轉換為多階段構建，並進入RUN apt-get install -y python3-pip ，我就會收到“ E：無法在多階段Docker構建中找到軟件包”

FROM gcc:8.2.0 as builder
# FROM ownyourbits/debiandev:latest

RUN apt-get update
# RUN apt-get install -y libxerces-c-dev automake cmake libboost-all-dev  build-essential
RUN apt-get install -y libxerces-c-dev automake cmake libboost-all-dev  build-essential
RUN git clone https://github.com/mypackage/mypackage-d.git
WORKDIR /mypackage-d/
RUN autoreconf -if
RUN ./configure --enable-silent-rules 'CFLAGS=-g -O0 -w' 'CXXFLAGS=-g -O0 -w' 'LDFLAGS=-g -O0 -w'
RUN make
RUN make install
RUN ls .

# Main Image
FROM library/python:3.7-stretch

COPY --from=builder /mypackage-d/mypackaged.bin /mypackage-d

RUN apt-get update
RUN apt-get install -y python3
RUN apt-get install -y python3-pip

RUN apt-get install -y postgresql-client

RUN apt-get install -y libxerces-c-dev

# For VIM
RUN apt-get install -y apt-file
RUN apt-file update
RUN apt-get install -y vim

RUN pip install --upgrade pip

COPY requirements.txt /
RUN pip3 install --trusted-host pypi.org -r /requirements.txt

WORKDIR /code

ENTRYPOINT ["/bin/bash", "start.sh"]

Answer 1

將COPY --from=builder命令移到apt-get install和pip install語句下面對我有用。
