问题
I am attempting to use conda to install spyder-kernels and instantiate a kernel on a remote server as per the instructions here: https://docs.spyder-ide.org/ipythonconsole.html
When I run the command python -m spyder_kernels.console I get an error:
/home/selah/anaconda3/bin/python: Error while finding module specification for 'spyder-kernels.console' (ModuleNotFoundError: No module named 'spyder-kernels')
However, I know that earlier today this command worked fine.
Any ideas about what is going on and how I might fix it?
Version info:
[selah@lothal ~]$ conda --version
conda 4.6.2
[selah@lothal ~]$ conda list | grep spyder-kernels
spyder-kernels 0.3.0 py36_0
[selah@lothal ~]$ find -name '*spyder-kernels*'
./anaconda3/pkgs/spyder-kernels-0.3.0-py36_0
./anaconda3/pkgs/spyder-kernels-0.3.0-py36_0.tar.bz2
./anaconda3/conda-meta/spyder-kernels-0.3.0-py36_0.json

Given your comment:
"However, I know that earlier today this command worked fine."
You may have a conda virtual environment set up which has become deactivated. Try this to see all your available conda environments:
conda env list
If there are any, you can do:
conda list -n whicheverenvyouchoose
to see if a given one has spyder_kernels installed.
If and when you find it, simply do:
conda activate whicheverenvyouchoose
If you somehow don't have any, first, create a conda virtual environment for your work with the following:
conda create -n whateveryoudcalltheenv python=x.y anaconda
where x.y is your preferred version of python.
then do:
. activate whateveryoudcalltheenv
Now, go ahead and install your packages via:
conda install -n whateveryoudcalltheenv stuff
At that point, you should be good to go.
When you're done with working in that environment, just:
source deactivate
No need to name it.
