[FIXED] Anaconda - Spyder no longer launching

Issue

I've been using anaconda Spyder for a few weeks for one of my classes and when I anaconda today, Spyder was not listed as installed. So I updated anaconda and restarted my MacBook and Spyder was back. Now, when I try launch Spyder, I get this error:

unittest: No module named 'lxml'

Ive tried reinstalling Spyder, using a different version of Spyder, but I can't seem to get past this error. If anyone could help id really appreciate it, I need to use this software for my class.

New error:

Solution

Try resetting spyder

conda activate your_spyder_env

spyder --reset

If that doesn't work try deleting the history lcoated as below and then re-running/reinstalling

user_dir/.config/spyder-py3

If that doesn't work try uninstalling, checking that all the files have been fully removed as below, updating conda, then reinstalling in a new environment

conda activate your_spyder_env

conda remove spyder

Check and make sure below or equivalent has properly removed. Note: Your first and last name appear to be present in the logs, just a headsup in case you want to obscure it from the web

user_dir/opt/anaconda3/lib/python3.9/site-packages/spyder

Reinstall

conda update anaconda

conda create --name new_spyder_env spyder
