Problem Description

First, I absolutely love Spyder 6, well done! One of my biggest issues with Spyder 5 was that it was such a pain to switch between environments. Now that it's so much easier, I have a suggestion for how to make it easier still.

Currently, when you open an environment that doesn't have spyder-kernels installed, it will say "An error occurred while starting the kernel" with instructions for what to do. But it would be nice if there were instead a dialog box that said "Would you like to install spyder-kernels into this environment?", do it, and then start the console.

What steps reproduce the problem?

1. Go to the console
2. Go to "New console in environment"
3. Select an environment that doesn't have spyder-kernels installed

What is the expected output? What do you see instead?

I would want an option to automatically install spyder-kernels into the selected environment.

Paste Traceback/Error Below (if applicable)

An error occurred while starting the kernel
The Python environment or installation whose interpreter is located at
    /home/user/anaconda3/envs/myenv/bin/python
doesn't have spyder‑kernels version >=3.0.0,<3.1.0 installed. Without this module and specific version is not possible for Spyder to create a console for you.

You can install it by activating your environment (if necessary) and then running in a system terminal:
    conda install spyder-kernels=3.0
or
    pip install spyder-kernels==3.0.*
