警告：我是 python 和 pipenv 的新手

我正在尝试使用shakedownwith创建可重现的 DC/OS 测试设置pipenv。我认为接下来的pipenv问题更多。

我第一次安装：

pipenv install dcoscli

如果我这样做，pipenv shell & pip list我可以看到：

...
dcoscli (0.5.7)
...

然后，我尝试安装dcos-shakedown，它抱怨它找不到dcoscli==0.5.7

pipenv install dcos-shakedown
CRITICAL:pip.index:Could not find a version that satisfies the requirement dcoscli==0.5.7 (from versions: 0.1.1, 0.1.2, 0.1.3, 0.1.4, 0.1.5, 0.1.6, 0.1.7, 0.1.8, 0.1.9, 0.1.10, 0.1.11, 0.1.12, 0.1.13, 0.1.14, 0.1.15, 0.2.0, 0.3.0, 0.3.1, 0.3.2, 0.3.3, 0.3.4, 0.3.5, 0.3.6, 0.4.0, 0.4.1, 0.4.2, 0.4.3, 0.4.4, 0.4.5, 0.4.6, 0.4.10, 0.4.11, 0.4.12, 0.4.13, 0.4.14)
Warning: Your dependencies could not be resolved. You likely have a mismatch in your sub-dependencies

尽管出现错误消息，但dcos-shakedown似乎已安装并正常工作。

pipenv shell
python

Python 3.6.3 (default, Oct  3 2017, 21:45:48) 
[GCC 7.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from shakedown import *
(succeeds)

安装失败后我的 Pipfile 如下所示：

[[source]]

url = "https://pypi.python.org/simple"
verify_ssl = true
name = "pypi"


[dev-packages]



[packages]

dcoscli = "*"
dcos-shakedown = "*"
behave = "*"


[requires]

python_version = "3.6"

我也尝试显式安装pipenv install dcoscli==0.5.7，但收到与上述相同的错误消息。

pip install我确实在两个依赖项的 virtualenv ( ) 中尝试了一个“普通” pipenv shell，它没有给我任何问题。（我确实在试验之间清理了virtualenv目录以避免污染）

我做错了什么还是我面临一些错误？

所以这对我来说很好。如果我在 MacOS 或 Ubuntu 上从头开始

现在看起来您可能正在pipenv从已经获取的venv或https://virtualenv.pypa.io/en/stable/运行

我会从香草壳开始。或者检查 shell 上的 PATH 变量是否没有指向系统上的“不同”python 二进制文件
