How to update jupyterlab using conda or pip

conda update jupyter will not automatically update jupyterlab. You have to explicitly request an update of jupyterlab:

conda update jupyterlab

You may need to specify conda-forge:

conda update -c conda-forge jupyterlab

EDIT: Trying to update to 3.0, conda update jupyterlab did not work for me (result of jupyter lab --version still was 2.x) and when I tried to specify conda-forge or jupyterlab=3.0 the command hung for too long. I gave up after almost an hour of solving environment. The following worked for me from the Anaconda shell:

conda uninstall jupyterlab
conda install -c conda-forge jupyterlab=3

I was getting frustrated by trying to update Jupyterlab on Anaconda and failing. Eventually I realized that this line of code works for me:

    conda update --all

If you prefer using pip:

pip install --upgrade jupyterlab

Or if you'd like a specific version:

pip install jupyterlab==1.2.4

Depending on your rights, you might also need to add a --user in there:

pip install jupyterlab==1.2.4 --user

After a lot of back-and-forth with the above methods with conda, none of which worked for me to upgrade nodejs to > v14.x - below is the solution that worked for me, thanks to the link below:

conda search nodejs # Search nodejs version under conda. conda install nodejs=14.7.0 -c conda-forge
