我是 docker 新手，一段时间以来一直在尝试解决此错误。我读过类似的帖子，但似乎没有任何效果。

完整错误：

failed to solve with frontend dockerfile.v0: failed to create LLB definition: failed to copy: httpReadSeeker: failed open: could not fetch content descriptor sha256:eff196a3849ad6541fd3afe676113896be214753740e567575bb562986bd2cd4 (application/vnd.docker.distribution.manifest.v1+json) from remote: not found
ERROR: Service 'nginx' failed to build : Build failed

我有三个 Dockerfile，一个用于我的 react 前端，一个用于 django 后端，一个用于 nginx。

前端 dockerfile：


COPY ./react_app/package.json .
RUN apk add --no-cache --virtual .gyp \
        python \
        make \
        g++ \
    && npm install \
    && apk del .gyp

COPY ./react_app .

ARG API_SERVER
ENV REACT_APP_API_SERVER=${API_SERVER}
RUN REACT_APP_API_SERVER=${API_SERVER} \ 
  npm run build

WORKDIR /usr/src/app
RUN npm install -g serve
COPY --from=builder /usr/src/app/build ./build

Django Python 后端 Dockerfile


WORKDIR /usr/src/app

ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1

COPY ./requirements.txt .
RUN pip wheel --no-cache-dir --no-deps --wheel-dir /usr/src/app/wheels -r requirements.txt

FROM python:3.7.9-slim-stretch
RUN apt-get update && apt-get install -y --no-install-recommends netcat && \
   apt-get autoremove -y && \
   apt-get clean && \
   rm -rf /var/lib/apt/lists/*

COPY --from=builder /usr/src/app/wheels /wheels
COPY --from=builder /usr/src/app/requirements.txt .
RUN pip install --no-cache /wheels/*
WORKDIR /usr/src/app
COPY ./entrypoint.sh /usr/src/app/entrypoint.sh

COPY ./django_app .

RUN chmod +x /usr/src/app/entrypoint.sh
ENTRYPOINT ["/usr/src/app/entrypoint.sh"]

和nginx dockerfile


FROM nginx:1.19.0-alpine

RUN rm /etc/nginx/conf.d/default.conf
COPY nginx.conf /etc/nginx/conf.d

WORKDIR /usr/src/app

我不知道从这里去哪里。我尝试了 5 或 6 个类似的堆栈溢出和更多 github 问题，但无济于事。谢谢，请告诉我。
