Conda not recognizing that I have node installed?

I open the terminal.

jupyter labextension install @jupyterlab/github

An error occured.
ValueError: Please install nodejs >=10.0.0 before continuing. nodejs may be installed using conda or directly from the nodejs website.
See the log file for details

Yet:

node -v

v14.5.0

What's going on, and how do I make conda find my node?

I had a similar problem and it was solved after I install the full package:

To install this package with conda run one of the following:

conda install -c conda-forge nodejs
conda install -c conda-forge/label/gcc7 nodejs
conda install -c conda-forge/label/cf201901 nodejs
conda install -c conda-forge/label/cf202003 nodejs

I had the same problem. The problem was I installed nodejs both with my conda package manager and in my system. I removed one of them (the conda nodejs package) and the problem solved.
