【问题描述】：
我有一个正在转换为 pipenv 的项目。当我第一次运行pipenv install 时，它开始正常，但多个依赖项失败。当我运行pip install -r requirements.txt 时，我没有问题。我正试图找出我可能做错了什么。
生成的 pipfile：
[[source]]

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

我得到了错误

但许多其他软件包也失败了。该错误显示它使用 Python 3.7，这是我的全局版本，但我在 Python 2.7.16 shell 中运行了上述所有命令，由 pipenv 本身启动（使用pipenv shell）。即使没有 shell，因为我在 pipfile 中明确列出了 Python 版本，我希望 pipenv 安装与版本匹配的包，尽管这可能是一个错误的假设？
