如何让docker在docker中运行？

Question

林在我的搬运工安装pipenv：

RUN pip install pipenv 
RUN cd /my/app/path/ && pipenv install 
RUN cd /my/app/path/ && pipenv shell 

即时得到错误：

Traceback (most recent call last): 
    File "/usr/local/bin/pipenv", line 11, in <module> 
    sys.exit(cli()) 
    File "/usr/local/lib/python2.7/dist-packages/pipenv/vendor/click/core.py", line 722, in __call__ 
    return self.main(*args, **kwargs) 
    File "/usr/local/lib/python2.7/dist-packages/pipenv/vendor/click/core.py", line 697, in main 
    rv = self.invoke(ctx)

    File "/usr/lib/python2.7/posixpath.py", line 54, in isabs 
    return s.startswith('/') 
AttributeError: 'NoneType' object has no attribute 'startswith' 

如果我运行

RUN cd /my/app/path/ && pipenv install --system 

代替，即时得到另一个错误：

但当我代替做到以下几点：

RUN pip install pipenv 
RUN cd /my/app/path && pipenv install 
RUN cd /my/app/path && pipenv install --system 

它的工作...

于是两个问题：第一：为什么pipenv shell给我这个错误，第二：为什么我以前做pipenv installpipenv install --system让它工作？

我想使用pipenv创建具有不同python版本和不同依赖版本的虚拟环境。

尝试

source `pipenv --venv`/bin/activate
