在某些计算机上构建的有效Pipfile不在其他计算机上构建，并且因依赖项错误而死亡。
我们运行pipenv install --dev时会看到此错误，尽管看起来six版本1.12.0应该符合约束集：
ERROR: ERROR: Could not find a version that matches six>=1.10.0,>=1.12,>=1.2,>=1.5.2,>=1.6.1,>=1.7.0,>=1.9.0,~=1.10.0

我们尝试了许多选项，例如pipenv install --ignore-pipfile，使用似乎正常运行的机器上的Pipfile.lock，但没有安装任何东西。运行pipenv graph不会产生任何输出。运行pipenv install --skip-lock失败，并显示原始错误。
