Within my virtual python 3.9x - environment on my Lubuntu 20.04 - System, I tried to install swifter via command line using pip install swifter.
This doesn't work out however, as the compatibility checks with several modules, such as jupyter-core, jupyter-client, jedi and decorator cannot be finished even after 1 hour running time.
The entire stdout of pip install swifter until interrupting the process forcefully via CTRL + C can be seen in what follows:

As a side note on the previous lengthy code-block: I tried to make foldable markdown/HTML-blocks work here as suggested in this post, but it is not enabled by the stackoverflow - engine at the moment.
