I tried to install the extension from the command line and got:

It looks like the issue comes from another extension.

Did you try to install the extension with jupyter labextension install jupyterlab-python-file?

What is the output of jupyter labextension list?

gioarma commented

Yes I used jupyter labextension install jupyterlab-python-file.
If I run jupyter labextension list I get:

JupyterLab v2.0.1
Known labextensions:
   app dir: /opt/anaconda3/share/jupyter/lab
        @jupyter-widgets/jupyterlab-manager v2.0.0  enabled  OK
        @jupyterlab/toc v3.0.0  enabled  OK
        @lckr/jupyterlab_variableinspector v0.5.0  enabled  OK
        @pyviz/jupyterlab_pyviz v1.0.0  enabled  OK
        jupyter-matplotlib v0.7.2  enabled  OK
        jupyterlab-python-file v0.4.0  enabled  OK

Build recommended, please run `jupyter lab build`:
    jupyterlab-python-file needs to be included in build

This is what I get if I run jupyter lab build:

*Jupyter Lab Build*
[LabBuildApp] JupyterLab 2.0.1 [LabBuildApp] Building in /opt/anaconda3/share/jupyter/lab [LabBuildApp] Building jupyterlab assets (build:prod:minimize) Build failed. Troubleshooting: If the build failed due to an out-of-memory error, you may be able to fix it by disabling the `dev_build` and/or `minimize` options.

If you are building via the jupyter lab build command, you can disable
these options like so:

jupyter lab build --dev-build=False --minimize=False

You can also disable these options for all JupyterLab builds by adding these
lines to a Jupyter config file named jupyter_config.py:

c.LabBuildApp.minimize = False
c.LabBuildApp.dev_build = False

If you don't already have a jupyter_config.py file, you can create one by
adding a blank file of that name to any of the Jupyter config directories.
The config directories can be listed by running:

jupyter --paths

Explanation:

  • dev-build: This option controls whether a dev or a more streamlined
    production build is used. This option will default to False (ie the
    production build) for most users. However, if you have any labextensions
    installed from local files, this option will instead default to True.
    Explicitly setting dev-build to False will ensure that the production
    build is used in all circumstances.

  • minimize: This option controls whether your JS bundle is minified
    during the Webpack build, which helps to improve JupyterLab's overall
    performance. However, the minifier plugin used by Webpack is very memory
    intensive, so turning it off may help the build finish successfully in
    low-memory environments.

An error occured.

@gioarma would you be able to try with JupyterLab 3.0, which was released about a month ago?

With 3.0, this extension does not require NodeJS anymore, and can be installed with:

pip install jupyterlab-python-file

Yes, now it works just fine!
