我需要在每个虚拟环境中安装Jupyter笔记本吗? [英] Do I need to install Jupyter notebook in every virtual environment?

问题描述

我使用pipenv将数据科学项目隔离到虚拟环境中.但是，运行Jupyter notebok不会访问本地环境，而是使用默认的IPyKernel.我已经看到，您可以在环境中注册虚拟环境，但这需要安装本身需要Jupyter的ipykernel软件包！

I isolate my data science projects into virtual environments using pipenv. However, running a Jupyter notebok does not access the local environment and uses the default IPyKernel. I've seen that you can register virtual environments from within the environment, but this requires installing the ipykernel package which itself requires Jupyter!

有没有避免这种情况的方法，而仅对所有虚拟环境使用一个Jupyter安装?

Is there anyway to avoid this and just use a single Jupyter install for all virtual environments?

推荐答案

通常，您将安装一次jupyter并在虚拟环境中执行以下操作:

Generally, you'd install jupyter once and do the following in your virtual environments:

pip install ipykernel  
python -m ipykernel install --user

当您运行多个Python版本时，这还不够.
这里有一个指南试图解决这个问题:

This isn't enough when you're running multiple Python versions.
There's a guide here that tries to address this:

它不是100％故障安全的，但可以帮助您避免一直重新安装jupyter笔记本电脑.

It's not 100% failsafe, but it can help you avoid reinstalling jupyter notebook all the time.
