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

    Do NOT use ```pip install --upgrade jupyterlab``` in a conda environment where jupyterlab was installed with conda, unless you plan to "dead-end" that conda environment (or possibly corrupt it permanently).

  • Hi I used this approach, then I found the version I installed is 3.3.2. However in below anaconda website the version is 3.5.0. How do I upgrade it to 3.5.0? Thanks https://anaconda.org/conda-forge/jupyterlab – roudan Oct 30 '22 at 19:38

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

    In fact `conda update --all` is a good to refresh and update the entire environment before upgrading a major package like JupyterLab, Jupyter Classic NB, or Spyder so that all the supporting packages are up-to-date before doing your update. This can help to repair the conda package index caused by packages inadvertently installed using pip into the conda environment. – Rich Lysakowski PhD Apr 07 '21 at 04:10

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

Experience has taught me, that when you need to upgrade multiple pip packages, the best way is to do it all at once (pip will find a good combination of versions and requirements).

So what I did is this.

  1. Figure out what jupyterlab uses (your output may differ):
$ jupyter --version
Selected Jupyter core packages...
IPython          : 8.9.0
ipykernel        : 6.20.2
ipywidgets       : 8.0.4
jupyter_client   : 8.0.1
jupyter_core     : 5.1.5
jupyter_server   : 2.1.0
jupyterlab       : 3.5.3
nbclient         : 0.7.2
nbconvert        : 7.2.9
nbformat         : 5.7.3
notebook         : 6.5.2
qtconsole        : 5.4.0
traitlets        : 5.8.1
  1. Put all those in a single line and run --upgrade:
$ pip install --upgrade IPython ipykernel  ipywidgets jupyter_client jupyter_core jupyter_server jupyterlab nbclient nbconvert nbformat notebook qtconsole traitlets

All went smoothly.

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
