这里有个-m的参数,依然可以通过python -h看看,大体就是通过python命令调去另一个venv的脚本。 -m mod : run library module as a script (terminates option list) 这里我们也不再多说,如果有兴趣可以参考手册或PEP 405文档。 venv — Creation of virtual environments — Python 3.10.7 documentation PEP 405...
$cdmy_project_folder$virtualenv venv 也可以创建一个指定python版本解释器的虚拟环境 $virtualenv -p /usr/bin/python2.7 venv 开始使用之前需要先激活 $sourcevenv/bin/activate 如果完成工作后需要取消激活,返回系统默认的python解释器环境. $deactivate 其他要点 执行virtualenv --no-site-packages将不会将系统安装的...
This list may be shorter or longer for you, depending on how many virtual environments VS Code discovers on your system. Use the arrow keys to find the virtual environment you just created:You’ll know that it’s the right one if the path to the interpreter displays as .\venv\Scripts\...

其一是通过Anconada Navigator可视化操作,选中Environments点击最下方的Create即可进入到创建虚拟环境的页面。 其二是在命令行通过指令进行创建,后续介绍的几种方案也是类似。 # 指令 conda create -n env1 python=3.8.8 指令中,env1是虚拟环境名称,可以自定义;python=3.8.8是指定python版本,可以自定义。

# 6. A list of environments, empty, is printed. # 7. Run: mkvirtualenv temp # 8. Run: workon # 9. This time, the "temp" environment is included. # 10. Run: workon temp # 11. The virtual environment is activated. # 提炼出来就是: ...
The main advantage of this approach is that you can use tools that help you manage virtual environments. You can easily list, activate, or remove them. And it doesn’t matter in which folder you currently are. That’s my preferred way too - it’s convenient to just run workon my-...
