为什么 Pipenv 没有选择我的 Pyenv 版本？

Question

我的系统 Python 版本是 3.8.5，但是我使用 pyenv 管理一个附加版本 3.6.0，以镜像我的项目部署到的服务器版本。我以前使用 virtualenv + virtualenvwrapper 来管理我的虚拟环境，但我听说过 pipenv 的好东西，并认为我会试一试。在我尝试使用 Python 3.6.0 之前一切都很好。流程是这样的：

$ mkdir test_project && cd test_project
$ pyenv shell 3.6.0
$ pipenv install django

我遇到了上一个问题Pipenv not recognizing Pyenv version?，并在我的.bashrc 文件中设置了环境变量PIPENV_PYTHON="$PYENV_ROOT/shims/python。无济于事。

使用系统 Python 3.8.5 版可以完美运行：

$ pyenv install django

Alternatively, run a command inside the virtualenv with pipenv run.

更新

虽然我仍然无法识别使用pyenv shell x.x.x 激活的python 版本，但通过删除PIPENV_PYTHON 环境变量，并使用pipenv install --python 3.6 创建一个新的virtualenv，pipenv 确实可以识别安装的pyenv 版本。

Answer 1

pipenv 不尊重 pyenv local 和 pyenv global (reference)

也许它也不尊重pyenv shell

我通常做你做的，指定python就像pipenv install --python 3.7

Answer 2

你可以试试这个让 Pipenv 遵循 Pyenv Python 版本：

将 Pipenv 定向到 shell 配置文件中的 Pyenv shim（这是 /.zshrc）

export PIPENV_PYTHON="$PYENV_ROOT/shims/python"

注意事项：

1. 确保您在 shell 配置文件中正确设置了 PYENV_ROOT。

2. 如果您使用其他版本的 python 创建 pipfile 和 pipfile.lock，您可能需要重新制作它们。

答案来自Pipenv docs、this Stackoverflow answer和bani（这个问题的另一个答案）。

Answer 3

在 pyenv 中如何设置 .bashrc 有不同的版本。这个对我有用

export PYENV_ROOT="$HOME/.pyenv"
export PATH="$HOME/.pyenv/bin:$PATH"
eval "$(pyenv init --path)"
eval "$(pyenv init -)"
