“找不到 jpeg 的头文件或库文件"在 Alpine Linux 上安装 Pillow

问题描述

我正在尝试在基于 python:alpine 的 Docker 容器中运行 Python 的 Scrapy.它以前可以工作，但现在我想使用 Scrapy 的 Image Pipeline 这需要我安装 Pillow.

I'm trying to run Python's Scrapy in a Docker container based on python:alpine. It was working before, but now I'd like to use Scrapy's Image Pipeline which requires me to install Pillow.

作为一个简化示例，我尝试了以下 Dockerfile:

As a simplified example, I tried the following Dockerfile:

FROM python:alpine
RUN apk --update add libxml2-dev libxslt-dev libffi-dev gcc musl-dev libgcc openssl-dev curl
RUN apk add libjpeg zlib tiff freetype lcms libwebp tcl openjpeg
RUN pip install Pillow

但是，当我尝试构建它时，我收到一个错误，其中包含以下内容:

However, when I try to build this I get an error which contains the following:

Traceback (most recent call last):
  File "/tmp/pip-build-ft5yzzuv/Pillow/setup.py", line 744, in <module>

During handling of the above exception, another exception occurred:

    raise RequiredDependencyException(msg)
__main__.RequiredDependencyException:

The headers or library files could not be found for jpeg,
a required dependency when compiling Pillow from source.

我查看了 https://pillow.readthedocs.io/en/上的要求latest/installation.html 并试图找到 Alpine 的相应包，虽然我找不到 libimagequant，所以这可能是罪魁祸首".尽管如此，回溯和错误消息似乎是在说 jpeg 丢失，而我已经安装了 openjpeg.

I went through the requirements on http://www.51sjk.com/Upload/Articles/1/0/341/341887_20230131091916226.html and tried to find the corresponding packages for Alpine, although one I couldn't find was libimagequant, so this might be the 'culprit'. Nonetheless, it the traceback and error message seem to be saying that jpeg is missing, whereas I have installed openjpeg.

如何修改 Dockerfile 以便 pip install Pillow 运行?

How can I modify the Dockerfile so that pip install Pillow runs?
