在Python开发中，虚拟环境（Virtual Environments）是一种非常实用的工具。它通过创建独立的环境来隔离项目依赖，避免不同项目之间的依赖冲突。本文将简要介绍虚拟环境的基本概念、其优势以及如何使用，并通过几个实际例子展示其应用。Virtual environments are a highly practical tool in Python development. They isolate p...
A virtual environment is a Python environment such that the Python interpreter, libraries and scripts installed into it are isolated from those installed in other virtual environments, and (by default) any libraries installed in a “system” Python, i.e., one which is installed as part of your...
In this tutorial, you'll learn how to use a Python virtual environment to manage your Python projects. You'll also gain a deep understanding of the structure of virtual environments created with the venv module, as well as the rationale behind using virt

cannot create virtual environments for arbitrarily installed python versions(无法创建任意 Python 版本的虚拟环境) is not upgrade-able via pip(无法通过 pip 进行升级) does not have as rich programmatic API(没有丰富的 API 编程方法扩展) 而这些不足之处在 Virtualenv 里都有了比较完善的解决方案。
使用pyenv-win 的 Virtual Environments 功能,你可以创建和管理独立的 Python 环境,这与 virtualenv 的功能非常相似。但是,与 virtualenv 不同的是,pyenv-win 的 Virtual Environments 是基于不同的 Python 版本创建的,而 virtualenv 则是基于同一 Python 版本的不同虚拟环境。
Python virtual environments my_envdirectory that is created by thepython3 -m venv my_envcommand. Is this correct? I am asking, because I am planning to create a second virtual environment, and to use a different/older version of Ptyhon. Somehow I feel I should be working from within the...
