ImportError：curl客户端需要pycurl库Docker + Django

Question

我正在码头化Django 2.2应用程序，并使用Pipenv进行环境管理。我想将SQS用作Django celery的代理。

我已经使用Pipenv安装了pycurl库

[packages]
...
pycurl = "*"

当我在本地运行芹菜时

pipenv run celery -A qcg worker -l info

它可以工作，但是当我使用docker image运行时>

docker run app:latest celery -A qcg worker -l info
给出错误

ImportError: The curl client requires the pycurl library.
Docerkfile中用于安装依赖项的命令

RUN set -ex \
    && BUILD_DEPS=" \
    build-essential \
    libpcre3-dev \
    libpq-dev \
    libcurl4-openssl-dev libssl-dev \
    " \
    && apt-get update && apt-get install -y --no-install-recommends $BUILD_DEPS \
    && export PYCURL_SSL_LIBRARY=nss \
    && pipenv install --deploy --system \
    \
    && apt-get purge -y --auto-remove -o APT::AutoRemove::RecommendsImportant=false $BUILD_DEPS
