我想构建一个docker环境，但是我得到了错误:无法满足的约束: python (缺失)：

Question

我试图运行一个模型，它要求我建立一个码头环境。我想我收到了一条关于我的蟒蛇的错误消息？我不太明白。

我在Docker Alpine Linux python (missing)中尝试过顶级答案，但仍然收到相同的错误消息。我想知道这是否是Dockerfile所要求的特定python包要求？我需要在模型所在的目录上一个一个地安装这些软件包吗？

RUN apk update && apk add gfortran \
    musl-dev bash python py-pip doxygen git graphviz

我安装了Python和Gfortran。

$ which python
/opt/anaconda3/bin/python

$ which gfortran
/usr/local/bin/gfortran

$ python
Python 3.7.6 (default, Jan  8 2020, 13:42:34) 
[Clang 4.0.1 (tags/RELEASE_401/final)] :: Anaconda, Inc. on darwin
Type "help", "copyright", "credits" or "license" for more information.

，这是我在终端机里的东西

$ sudo docker build -t simstrat:alpine .

，这是我拥有的Docker文件：

FROM alpine:latest
MAINTAINER SURF Team "davide.vanzo@eawag.ch"

# get the tools we need
RUN apk update && apk add gfortran \
    musl-dev bash python py-pip doxygen git graphviz

RUN pip install FoBiS.py ford pygooglechart

# root dir
RUN mkdir /home/Simstrat
WORKDIR /home/Simstrat

# calls that are needed to build and start the container with the build environment:
# docker build -t simstrat:alpine .
# docker create --name simstrat -it -v <pathToLocalGitRepoDirectory>:/home/Simstrat simstrat:alpine
# docker start simstrat
# docker exec -it simstrat bash

Answer 1

回顾过去，这个问题现在似乎有点傻了。原始的docker文件有"python“而不是"python3”，这就是我得到错误的原因。

RUN apk update && apk add gfortran \
    musl-dev bash python3 py-pip doxygen git graphviz````
