“在jpeg上找不到头文件或库文件”在Alpine Linux上安装Pillow
我想在基于python的Docker容器中运行Python的Scrapy ：alpine 。 这是工作之前，但现在我想使用Scrapy的图像pipe道 ，这需要我安装枕头。
作为一个简单的例子，我尝试了下面的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，当我试图build立这个我得到一个错误，其中包含以下内容：
Traceback (most recent call last): File "/tmp/pip-build-ft5yzzuv/Pillow/setup.py", line 744, in <module> zip_safe=not debug_build(), ) File "/usr/local/lib/python3.6/distutils/core.py", line 148, in setup dist.run_commands() File "/usr/local/lib/python3.6/distutils/dist.py", line 955, in run_commands self.run_command(cmd) File "/usr/local/lib/python3.6/distutils/dist.py", line 974, in run_command cmd_obj.run() File "/usr/local/lib/python3.6/site-packages/setuptools/command/install.py", line 61, in run return orig.install.run(self) File "/usr/local/lib/python3.6/distutils/command/install.py", line 545, in run self.run_command('build') File "/usr/local/lib/python3.6/distutils/cmd.py", line 313, in run_command self.distribution.run_command(command) File "/usr/local/lib/python3.6/distutils/dist.py", line 974, in run_command cmd_obj.run() File "/usr/local/lib/python3.6/distutils/command/build.py", line 135, in run self.run_command(cmd_name) File "/usr/local/lib/python3.6/distutils/cmd.py", line 313, in run_command self.distribution.run_command(command) File "/usr/local/lib/python3.6/distutils/dist.py", line 974, in run_command cmd_obj.run() File "/usr/local/lib/python3.6/distutils/command/build_ext.py", line 339, in run self.build_extensions() File "/tmp/pip-build-ft5yzzuv/Pillow/setup.py", line 545, in build_extensions raise RequiredDependencyException(f) __main__.RequiredDependencyException: jpeg During handling of the above exception, another exception occurred: Traceback (most recent call last): File "<string>", line 1, in <module> File "/tmp/pip-build-ft5yzzuv/Pillow/setup.py", line 756, in <module> raise RequiredDependencyException(msg) __main__.RequiredDependencyException: The headers or library files could not be found for jpeg, a required dependency when compiling Pillow from source. Please see the install instructions at: https://pillow.readthedocs.io/en/latest/installation.html
我经历了https://pillow.readthedocs.io/en/latest/installation.html的要求，并试图find相应的软件包，虽然我找不到libimagequant ，所以这可能是'罪魁祸首”。 尽pipe如此，它的追踪和错误消息似乎是说， jpeg缺失，而我已经安装了openjpeg 。
我如何修改Dockerfile使pip install Pillow运行？
在稍后似乎已被删除的评论中，有人指向我https://github.com/python-pillow/Pillow/blob/c05099f45c0d94a2a98c3609a96bdb6cf7446627/depends/alpine_Dockerfile 。 基于该Dockerfile我修改我自己的如下：
FROM python:alpine RUN apk --update add libxml2-dev libxslt-dev libffi-dev gcc musl-dev libgcc openssl-dev curl RUN apk add jpeg-dev zlib-dev freetype-dev lcms2-dev openjpeg-dev tiff-dev tk-dev tcl-dev RUN pip install Pillow
现在它build立成功。
你看过这个QA吗？ 在Linux中安装Pillow（Python模块）时失败
他们说你必须更新你的点子并安装libjpeg-dev。
你有没有尝试创build一个requirements.txt并将其插入到Dockerfile中：
RUN apt-get update -qq && apt-get install build-essential g++ flex bison gperf ruby perl \ mysql-client \ libsqlite3-dev libmysqlclient-dev libfontconfig1-dev libicu-dev libfreetype6 libssl-dev \ libpng-dev libjpeg-dev python libx11-dev libxext-dev -y ENV PYTHONUNBUFFERED 1 RUN mkdir /code WORKDIR /code ADD requirements.txt /code/ COPY . /code RUN pip install -r requirements.txt ADD . /code/
