为什么Pipenv不选择我的Pyenv版本？

问题描述

我的系统Python版本是3.8.5，但是我使用pyenv来管理另一个版本3.6.0，以镜像项目所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，但是我在pipenv上听到了很多很棒的事情，并认为我会尝试一下。在尝试使用Python 3.6.0之前，一切都很棒。流是这样的：

$ 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pipenv_PYTHON="$PYENV_ROOT/shims/python文件中设置了环境变量.bashrc。无济于事。

使用系统Python版本3.8.5可以完美工作：

$ pyenv install django

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

更新

尽管我仍然无法通过删除pyenv shell x.x.x环境变量并使用pipenv_PYTHON创建一个新的virtualenv来识别由pipenv install --python 3.6激活的python版本，但pipenv确实可以识别pyenv版本已安装。

解决方法

pipenv不尊重pyenv local和pyenv global（reference）

也许它也不尊重pyenv shell

我通常会做您所做的事，像pipenv install --python 3.7这样指定python

您可以尝试使Pipenv遵循Pyenv Python版本：

在您的shell配置文件（这是/.zshrc）中将Pipenv定向到Pyenv垫片

export PIPENV_PYTHON="$PYENV_ROOT/shims/python"

注意：

确保在外壳程序配置文件中正确设置了PYENV_ROOT。
如果使用其他版本的python创建pipfile和pipfile.lock，则可能必须重新制作它们。
