我正在使用 pyenv 来管理 python 安装和虚拟环境。我的 Mac (Catalina) 上安装了多个 python。
\n对于一个项目，我需要 python 3.6。我知道 conda 提供了使用特定 python 版本创建虚拟环境的可能性，但我想尝试 pyenv 来管理不同的 python 安装。
\n我遵循安装指南并遵循基本的git check out步骤（对于 zsh）。
\n安装完成后，我可以.pyenv在我的主目录中找到一切似乎都正常。我使用 pyenv 成功安装了 python 3.6。当我运行pyenv versions以列出所有 python 安装（并切换到 conda 安装作为测试）时，输出不包含任何原始 python 安装（请参阅上面的列表）。输出：
\xe2\x96\xb6 pyenv versions\n* system (set by /Users/DVerb5/.pyenv/version)\n 3.6.12\n我怎样才能让 pyenv 也找到我的其他 python 安装？我尝试做一些研究，似乎是可能的。我看了一下下面的两页，看起来很有希望，但无法弄清楚。
\n\n正如前面提到的，我使用 zsh，这是我的 .zshrc 的内容

如果你通过 pyenv 本身安装它，它就会工作。例如，如果您运行pyenv install 3.7.4，您将获得由 pyenv 管理的 3.7.4。我不知道有什么方法可以让 pyenv 找到以前安装的版本，但是添加新版本确实很容易。
