After upgrading Spyder to version 4.2.1 on Ubuntu 18.04, it complaints, for dependencies, about
jedi = 0.17.2 : None (NOK)
parso = 0.7.0 : 0.8.1 (NOK)
I tried to install jedi, and parso using pip3 as below:
pip3 install jedi parso
But it does not fix the error.
It seems the problem is fixed when I install "Anaconda3-2020.11-Linux-x86_64.sh"
cd ~ballah/Downloads
chmod +x Anaconda3-2020.11-Linux-x86_64.sh
sudo ./Anaconda3-2020.11-Linux-x86_64.sh
You can check the dependencies from Help menu whether all they are resolved.
