我在Docker中安装pipenv：

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

我收到错误：

  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)

    return s.startswith('/')

如果我跑步

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

相反，即时通讯收到另一个错误：

但是当我改为执行以下操作时：

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

这是工作…

于是两个问题：第一：为什么pipenv shell给我这个错误，第二：为什么我必须做pipenv install之前pipenv install

--system得到它的工作？

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。

回答：

考虑到您的问题，据我所知，最简单的方法是更新到的最新版本pipenv。它仍在开发中，因此很快就解决了问题。

我们在生产中使用pipenvwith docker。我们真的很喜欢。有几件事要牢记：

  1. 您需要使用--systemflag，因此它将所有软件包安装到系统python中，而不是安装到中virtualenv。由于docker容器不需要具有virtualenvs

  2. 您需要使用--deploy标志，所以如果您Pipfile.lock的版本过时，构建将失败

  3. 您需要使用--ignore-pipfile，因此不会与我们的设置混淆

检查官方文档，以确保此信息是最新的。

总而言之：

pipenv install --system --deploy --ignore-pipfile

还有一件事。如果您Dockerfile在开发和生产中都使用相同的--dev标记，那么最好仅在开发环境中使用flag。

另外，请查看我们的django项目模板以查看完整的示例：wemake-django-

template
