Question

我正在对我的django应用进行docker化，如果您使用django image字段，您都知道，您需要使用Pillow软件包，但是当前我的docker安装了所有软件包，并在尝试安装pillow时显示错误

我的Dockerfile

# pull official base image
FROM python:3.7-alpine

# set work directory
WORKDIR /app

# set environment variables
ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1
ENV DEBUG 0

# install psycopg2
RUN apk update \
    && apk add --virtual build-deps gcc python3-dev musl-dev \
    && apk add postgresql-dev \
    && pip install psycopg2 \
    && apk del build-deps

# install dependencies
COPY ./requirements.txt .
RUN pip install -r requirements.txt

# copy project
COPY . .

# collect static files
RUN python manage.py collectstatic --noinput

# add and run as non-root user
RUN adduser -D myuser
USER myuser

# run gunicorn
CMD gunicorn projectile.wsgi:application --bind 0.0.0.0:$PORT

这是requirements.txt文件

Django==2.2.2
Pillow==5.0.0
dj-database-url==0.5.0
gunicorn==19.9.0
whitenoise==4.1.2
psycopg2==2.8.4

我没有发现问题，为什么pilow没有安装，它抛出错误，如下所示：

The headers or library files could not be found for zlib,

有人可以帮助我解决此错误吗？

谢谢

您可以在apk添加部分中添加zlib-dev并在那里安装枕头。例如（注释部分中有解释）：

RUN apk update \
    && apk add --virtual build-deps gcc python3-dev musl-dev zlib-dev postgresql-dev jpeg-dev \  # will be removed after dependent python packages are installed
    && apk add postgresql zlib jpeg \  # these packages won't be deleted from docker image
    && pip install psycopg2 Pillow==5.0.0 \  # Here I am installing these python packages which have dependencies on the libraries installed in build-deps, because later build-deps will be deleted
    && apk del build-deps  # for reducing the size of the Docker Image, we are removing the build-deps folder

# install dependencies
COPY ./requirements.txt .

RUN pip install -r requirements.txt
# Rest of the code

枕头套件的Docker Django安装错误
