Problem:
- According to [pipx
documentation](https://pipx.pypa.io/stable/docs/#pipx-install), `pipx
install` doesn't have --upgrade argument. Running `pipx install
--upgrade pynvim` results in an error "unrecognized arguments:
--upgrade"
- In file if_pyth.txt:317, it says "Implementation is ... written in C".
This is not true for Nvim, since find_module logic of Nvim's Python
interface is implemented in Python.
(fdaae821a9/pynvim/plugin/script_host.py (L217))
- $NVIM_LISTEN_ADDRESS has been deprecated.
- `:Next` is a core command, not termdebug plugin command. Termdebug
uses `:Over` to send command `next` to gdb
Solution:
- Just use `pipx install pynvim`
