I have tried to install jupyter lab on my Kubuntu machine. If I install jupyter lab with 'pip3 install jupyter jupyterlab' the command 'jupyter notebook' works completly fine. But if I try to run 'jupyter lab' every time I get the message:
Traceback (most recent call last):
File "/usr/local/bin/jupyter", line 11, in <module>
sys.exit(main())
File "/usr/local/lib/python3.6/dist-packages/jupyter_core/command.py", line 230, in main
command = _jupyter_abspath(subcommand)
File "/usr/local/lib/python3.6/dist-packages/jupyter_core/command.py", line 133, in _jupyter_abspath
'Jupyter command `{}` not found.'.format(jupyter_subcommand)
Exception: Jupyter command `jupyter-lab` not found.
What is wrong?
I tried to reinstall jupyter and jupyterlab multiple times with the same issue.

If you are running the latest version of Python (currently 3.14), JupyterLab will not install. It will go through the process then come back with an error:

The only solution I found was to install Python 3.13 then install JupyterLab from there.

Do this by running export PATH=$PATH:~/.local/bin
for your current session

In my ubuntu installation this was qused by not using sudo before the install.
sudo pip install jupyterlab
If you already installed jupyterlab, and it dit not work, you can install again using sudo, you dont need to remove the old version first for it to work

I was using conda to install
conda install -c conda-forge jupyterlab
and this error came about.
I simply used this command to get it to run.
pip install jupyterlab

Once installed you just have to run
pip install jupyterlab
~/.local/bin/jupyter-lab
and ready and open browser http://localhost:8888/lab

if anyone still struggling ... try:
find ~ -name jupyter-lab
and then:
export PATH=[path]
then try again: jupyter lab
note:
don't add any extra spaces and PATH is case sensitive and if u still struggling just try to install any missing pkgs after hosting to the main path by opining another tab or changing the path to main.
and then host to localhost:8888/lab
that should works fine...

ubuntu can not find the jupyter-lab because it is not in path.
in order to check the place of installment. run below command
find ~ -name jupyter-lab
possible result: /home/soshiant/.local/bin/jupyter-lab
for adding a directory to the Linux path you can follow below link:

Install with Anaconda

conda install -c conda-forge jupyter
conda install -c conda-forge jupyter_contrib_nbextensions

well the problem is like this:
the jupyterlab
module has not been packaged for debian, but the jupyterlab_server package has, named python3-jupyterlab-server
.
please sudo apt install python3-jupyterlab-server
.
then, as your user, run pip3 install jupyterlab, that will install it in your ~/.local/bin
a few programs, the missing jupyter-lab
among them.
last, but not least, run jupyter-serverextension enable --py jupyterlab
.
to be able to run jupyter lab
, you first need to run export PATH="/home/$(whoami)/.local/bin:"$PATH
. this command will run automatically if added to your ~/.bash_profile
.

When installing jupyterlab, we may get warning like this:
Installing collected packages: jupyterlab
WARNING: The scripts jlpm, jupyter-lab, jupyter-labextension and jupyter-labhub are installed in '/home/tln/.local/bin' which is not on PATH.
Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.
Successfully installed jupyterlab-3.0.14
So as per this warning, scripts like jupyter-lab will be unavailable unless added to the PATH.
Use below command to add these scripts to be able to use from command line:
tln@tln-X550LD:~$ export PATH="$HOME/.local/bin:$PATH"
That's it. This worked fine for me.

In my case, the only way to fix this was to add the following directory to the PATH
in Linux:
/home/ubuntu/.local/bin

I got this same error every time I forgot to activate the virtualenv jupyterlab was installed into. After activating the virtualenv, all's well.
With pip
$ source [path_to_venv]/bin/activate
With pipenv
$ pipenv shell
Then, with a prompt indicating an activated shell, you can enter your command
(venv) $ jupyter lab
With conda or other more holistic python environments, you probably use their gui to activate a virtualenv with jupyter and jupyterlab installed.

If you face -bash: jupyter-lab: command not found
or -bash: jupyter: command not found
, etc., you can look for "jupyter-lab" and enter that full path instead.
Mac:
$ /Users/mark/venv/bin/jupyter-lab
Windows:
C:\mark\venv\Scripts\jupyter-lab.exe

I had the same error on Windows 10. It was with pip install jupyterlab
. Then after the error I uninstalled it with pip and reinstalled with "pip install jupyterlab". Everything worked flawlessly thereafter.
In your case you're using pip3. Try it as above or see if pip3 needs an update.

Its the space. Its always the space. Never ever use spaces within package name. Its always either namepart1-namepart2 or namepart1namepart2. This is because arguments are separated by space. So if you put space in between, it makes pip
think that you want to install two different packages named jupyter
and lab
. Just use:
python -m pip install jupyterlab
Or simply:
pip install jupyterlab
No need to uninstall or reinstall anything. However to run jupyter lab server you might want to add spaces as follows:
jupyter lab
