由于某种原因，我无法在 docker 中安装 python 的 PIL 模块。这是我所拥有的描述:
要求.txt
Pillow
flask
redis
Dockerfile
FROM python:2.7
ADD . /code
WORKDIR /code
RUN pip install -r requirements.txt
CMD python app.py
app.py
import PIL
命令
$ sudo docker build -t web .
Installing collected packages: Pillow, Werkzeug, MarkupSafe, Jinja2, itsdangerous, flask, redis
Successfully installed Jinja2-2.8 MarkupSafe-0.23 Pillow-2.9.0 Werkzeug-0.10.4 flask-0.10.1 itsdangerous-0.24 redis-2.10.3

Step 4 : CMD python app.py

---> d62996658bd6
Removing intermediate container e71453f2fab6
Successfully built d62996658bd6
$ sudo docker-compose up
这是我得到的:
输出
web_1 | File "app.py", line 1, in <module>
web_1 | import PIL
web_1 | ImportError: No module named PIL
我想也许在 requirements.txt 中添加 PIL 会起作用，但这是我构建时发生的情况
$ sudo docker build -t web .
....
Collecting PIL (from -r requirements.txt (line 1))
Could not find a version that satisfies the requirement PIL (from -r requirements.txt (line 1)) (from versions: )
Some externally hosted files were ignored as access to them may be unreliable (use --allow-external PIL to allow).
No matching distribution found for PIL (from -r requirements.txt (line 1))
知道从这里应该做什么吗？
最佳答案
PIL 将是 Python Imaging Library (PIL)
(有时， you would need import Image instead of import PIL )
根据“How do I install python imaging library (PIL)? ”，您还需要安装其他组件
sudo apt-get build-dep python-imaging
sudo apt-get install libjpeg62 libjpeg62-dev
pip install PIL
另请参阅
a5huynh/scrapyd-playground/Dockerfile 以获取使用 Pillow(Python 成像库)依赖项的示例。(但请注意，如 Hugo comments below ，这混合了两个模块:PIL 和 Pillow。
Pillow 是经过维护的前叉，是原始未维护 PIL 的直接替代品，因此您不应同时安装两者)
RUN apt-get update && apt-get install -y \
python-dev python-pip python-setuptools \
libffi-dev libxml2-dev libxslt1-dev \
libtiff4-dev libjpeg8-dev zlib1g-dev libfreetype6-dev \
liblcms2-dev libwebp-dev tcl8.5-dev tk8.5-dev python-tk
# Add the dependencies to the container and install the python dependencies
ADD requirements.txt /tmp/requirements.txt
RUN pip install -r /tmp/requirements.txt && rm /tmp/requirements.txt
RUN pip install Pillow

Pillow==2.6.1
Scrapy==0.24.4
