提问by kampta
This might be silly but I am unable to install cPicklewith python 3.5 docker image
这可能很愚蠢，但我无法cPickle使用 python 3.5 docker 映像进行安装
Dockerfile

When I try to build the image
当我尝试构建图像时
$ docker build -t sample .
Sending build context to Docker daemon 3.072 kB
Step 1 : FROM python:3.5-onbuild
# Executing 3 build triggers...
Step 1 : COPY requirements.txt /usr/src/app/
Step 1 : RUN pip install --no-cache-dir -r requirements.txt

Collecting cpickle (from -r requirements.txt (line 1))
Could not find a version that satisfies the requirement cpickle (from -r requirements.txt (line 1)) (from versions: )
No matching distribution found for cpickle (from -r requirements.txt (line 1))
You are using pip version 7.1.2, however version 8.1.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
The command '/bin/sh -c pip install --no-cache-dir -r requirements.txt' returned a non-zero code: 1

cPicklecomes with the standard library… in python 2.x. You are on python 3.x, so if you want cPickle, you can do this:
cPickle带有标准库......在python 2.x中。你在 python 3.x 上，所以如果你想要cPickle，你可以这样做：
>>> import _pickle as cPickle
However, in 3.x, it's easier just to use pickle.
但是，在 3.x 中，使用pickle.
No need to install anything. If something requires cPicklein python 3.x, then that's probably a bug.
无需安装任何东西。如果cPickle在 python 3.x 中需要某些东西，那么这可能是一个错误。
