网络工程师 Python 基础语法-环境搭建(第0节,Python安装) 我们先来聊聊其中一个容易在IDE中犯迷糊的概念——Python虚拟环境(Virtual environment),主要演示在Window10环境下新建Python虚拟环境并与Pycharm进行联动。 〇、参考资料 本文部分参考知乎专栏@弈心《网路行者》实验思想,推荐移步阅读。 本文部分参考书籍《Python...
1.前提必须安装好python环境,并检查电脑系统环境path是否有python路径:打开cmd输入python即可看到安装的python信息,检验python是否安装成功 2.安装虚拟环境:pipinstall virtualenv 3.创建虚拟环境:virtualenv envname 4.进入虚拟环境: 4.1 到虚拟环境的位置(目录)的Scripts中: cd 虚拟环境的位置的Scripts 4.2 然后在激活(...
如果有的工程,用到了某些特殊的包,即除了该工程,别的工程大概率是用不到的,这种情况,我们就没有必要单独将其添加到系统package中,可以将其安装在virtual environment(venv)中 进入工程,执行:python -m venv xxx,xxx为创建的文件夹名称,执行命令后会把与Python虚拟环境有关的文件放到XXX里面 进入该工程的venv/Scri...

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
Now type the following at a cmd prompt in order to automatically create a virtual environment, and then download and install ActivePython 3.6 into it: state activate ActiveState/ActivePython-3.6 For Mac and Linux users, run the following command to install the State Tool: sh <(curl -q https...
Python venv Thevenvmodule enables to create lightweight virtual environments with their own site directories. Each virtual environment has its own Python binary (which matches the version of the binary that was used to create this environment) and can have its own independent set of installed Pytho...
