Issues installing nest-simulator=2.20.* via conda

[proteino]

Describe the bug
I want to install an older version of nest via conda (preferably 2.20.*), but conda search -c conda-forge nest-simulator only shows versions >= 3.3. In the Documentation (https://nest-simulator.readthedocs.io/en/stable/installation/conda_forge.html#conda-forge-install), the following command is proposed:
conda create --name nest_2_18_0 -c conda-forge nest-simulator=2.18.0=*,
but it does not work (error message: zsh: no matches found: nest-simulator=2.18.0=*)

Desktop/Environment (please complete the following information):

• OS: Mac-OS 14.4.1
• Shell: zsh

@proteino We unfortunately do not have the capacity to prepare conda packages for older NEST versions. I would also strongly recommend to install NEST 3.7 since newer NEST versions contain many improvements and bug fixes. If you need a NEST 2 version to run existing model code for comparison, you can either build NEST 2.20.2 on your computer from the sources or download the NEST 2.20.2 Live Media and run that as a virtual machine in, e.g., VirtualBox.
