Upgrade to python 3.8 using conda

问题

Python 3.8.0 is out, but I haven't been able to find any post on how to update to python 3.8 using conda - maybe they will wait for the official release? Any suggestions?

回答1:

You can update your python version to 3.8 in conda using the command

conda install -c anaconda python=3.8

as per https://anaconda.org/anaconda/python. Though not all packages support 3.8 yet, running

conda update --all

may resolve some dependency failures. You can also create a new environment called py38 using this command

conda create -n py38 python=3.8

Edit - note that the conda install option will potentially take a while to solve the environment, and if you try to abort this midway through you will lose your Python installation (usually this means it will resort to non-conda pre-installed system Python installation).

Open Anaconda Prompt (base):

1. Update conda:

conda update -n base -c defaults conda

2. Create new environment with Python 3.8:

conda create -n python38 python=3.8

3. Activate your new Python 3.8 environment:

conda activate python38

4. Start Python 3.8 with any of these commands:

python
jupyter notebook
ipython
