Error trying to install extensions in jupyter lab 2.2.6

  • 772

I am trying to transition from jupyter to jupyter lab2.0. I have installed the package in a fresh environment. When trying to install some of the extensions that come by default in the package, I always get the error

"@jupyterlab/translation" is not a valid npm package

The error is reproduced with any of the extensions that come by default.

I have installed: python 3.8.5, JupyterLab v2.2.6 andnodejs 10.13.0

On the other hand, how can you upgrade to jupyter lab 3? The option indicated by jupyterlab, conda conda install -c conda-forge jupyterlab has installed version 2.

What can be the cause? How can i solve this problem?. I will appreciate help.

python

    Whenever you want to install a specific version of any package, both with pipand with condayou can use the syntax =<version_paquete>at the end of the installation. In your case with Anaconda it would be:

    conda install -c conda-forge jupyterlab=3

    With pip :

    pip install jupyterlab=3

    If you want to be more specific you can specify the version or even the patches, for example here we install the first patch 3.0.1:

    conda install -c conda-forge jupyterlab=3.0.1

  2. The problem was that I had not finished all the steps for the correct installation of nodejs and npm . The following two statements remained to be executed.

    npm config set registry http://registry.npmjs.org/
jlpm config set registry https://registry.yarnpkg.com/
