Need help installing Anaconda and Spyder

Question

so i'm having some bad issues with my conda installation. I'm running this on MacOS Monterey 12.4

I installed the latest version "Anaconda3-2022.05-MacOSX-x86_64.sh" I then installed an env for spyder.

conda create -n spyder spyder

Everything seems to go ok, however everytime I attempt to run my code I get a spyder internal problem.

Traceback (most recent call last):
  File "/Users/person.blank/anaconda3/envs/spyder/lib/python3.9/site-packages/qtconsole/base_frontend_mixin.py", line 138, in _dispatch
    handler(msg)
  File "/Users/person.blank/anaconda3/envs/spyder/lib/python3.9/site-packages/spyder/plugins/ipythonconsole/widgets/debugging.py", line 278, in _handle_input_request
    return super(DebuggingWidget, self)._handle_input_request(msg)
  File "/Users/person.blank/anaconda3/envs/spyder/lib/python3.9/site-packages/qtconsole/frontend_widget.py", line 512, in _handle_input_request
    self._readline(msg['content']['prompt'], callback=callback, password=msg['content']['password'])
  File "/Users/person.blank/anaconda3/envs/spyder/lib/python3.9/site-packages/qtconsole/console_widget.py", line 2422, in _readline
    self._show_prompt(prompt, newline=False, separator=False)
TypeError: _show_prompt() got an unexpected keyword argument 'separator'

After this I removed and recreated the spyder env with:-

conda create -n spyder -c conda-forge spyder

When I attempt to launch spyder it never connects to the kernel in IPython Console. So at this point I tried doing another:

conda update --all

This updates the files, but when I launch spyder again I get a missing dependencies.

Mandatory:

qtpy >=2.1.0 : 2.0.1 (NOK)

Should it be this difficult to get anaconda and spyder working? I've always had it working without issue in the past. Anyway any help in solving this would be gratefully appreciated.

Answer 1

So after research this extensively I thought I would provide the solution that ultimately worked.

To resolve this issue you need to create an env from the conda-forge repo, in order to get the compatible versions of spyder and the spyder kernels.

conda create -n spyder-cf -c conda-forge spyder jupyter_client=7.3.1

So just breaking this down for completeness:-

Creates an env with the name spyder-cf

create -n spyder-cf

Use the conda-forge repo

-c conda-forge

Install spyder and the jupyter client from conda-forge

spyder jupyter_client=7.3.1

Once done you can activate the spyder-cf env and run spyder. However if you wish to use alternative env's then simply create the env you like and open it from spyder. For example, if I want a python 3.10 env I would do the following:

conda create -n env310 -c conda-forge python=3.10 spyder-kernels

It's important to install this from conda-forge so that you get the correct spyder kernel headers.

Change to the spyder-cf env

activate spyder-cf

Activate your python 3.10 env

spyder activate env310
