How to update jupyterlab using conda or pip

How do you update jupyterlab using conda or pip?

I understand that conda update jupyter updates jupyter notebook (I have Anaconda), but I'm not sure this takes care of jupyterlab as well.

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:

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