Python 3 - Pipenv 无法安装出现错误

Question

我是 python 新手，正在尝试安装依赖项。我知道pipenv install 安装了Pipfile.lock，这让我可以安装我需要的依赖项。以下是错误本身

Answer 1

Pipfile.lock 不会安装所需的依赖项或软件包，而是对通过 Pipenv 安装的依赖项进行最终更新检查。

高级的 Pipenv 用于在 python 环境中运行、安装和执行已安装的包。它还管理您的虚拟环境。

所以基本上，整个状态由您选择的 pip 环境和 virtualenv 组成。

如果您愿意，可以通过以下方式绕过锁定步骤：pipenv install --skip-lock。在大多数情况下，pipfile.lock 错误是由于 pipfile 中的拼写错误而发生的。

这是一个很好的教程，看这个link。
