Notebook: jupyter notebook Error executing Jupyter command 'notebook': [Errno 2] No such file or directory

[psbill2614]

Hi just installed Anaconda 2.1.0 (x86_64) for one of my course on MAC OS.
()Installation went OK
()PATH was updated
()ran the following commands and all seem to go OK.

conda update conda
conda update ipython
conda update pip
conda install bokeh
()version query returns
conda --version
conda 4.4.9

As per the instruction i should have notebook package installed.
But i get the follwing error

XXXXX@Admins-MacBook-Pro ~ $ jupyter notebook
Error executing Jupyter command 'notebook': [Errno 2] No such file or directory

conda list only has ipython notebook

gsandhu@Admins-MacBook-Pro ~ $ conda list | grep notebook
ipython-notebook 2.2.0 py27_0

Previously i tried updating jupyter using "pip install jupyter" and i was able to start the notebook but then there were issues in kernal . So i uninstalled everything and started from fresh.

Can anyone please guide me through this? Thanks in Advance

@takluyver
Hi,

can you please help me in this?

[takluyver]

Does jupyter-notebook work? I.e. try with a - instead of a space. The jupyter command is looking for other commands like that.

[psbill2614]

Thanks! jupyter-notebook does not work either. "ipython notebook" also does not work.

Here is the OP to jupyter-notebook:
-bash: /usr/local/bin/jupyter-notebook: /usr/local/opt/python/bin/python2.7: bad interpreter: No such file or directory

On trying to update conda for jupyter i see the following.

(root) (root)gsandhu@Admins-MacBook-Pro bin $ conda update jupyter

PackageNotInstalledError: Package is not installed in prefix.
prefix: /Users/gsandhu/anaconda
package name: jupyter

Should i just reinstall everything and try again?

to clean everything will these commands give me a clean slate?
rm -rf ~/anaconda
m -rf ~/.condarc ~/.conda ~/.continuum

Only 1 env.
(root) (root)gsandhu@Admins-MacBook-Pro bin $ conda info --envs

conda environments:

#
base * /Users/gsandhu/anaconda

[psbill2614]

Another information if it can give some hit. When i used "conda update conda" first time there is some error at the bottom.

I ran

pip install jupyter and then i can load the notebook. But kernal stops with the following error

[takluyver]

Update the ipykernel package - it should be fixed by 4.7 or newer. https://github.com/ipython/ipykernel/pull/278

[aaronpenne]

Same issue fixed for me by updating conda and reinstalling jupyter:

conda update -n base conda
conda install jupyter

[akashshah26595]

I faced similar issue. This is what I did to fix the issue (on Ubuntu) :

• sudo apt-get remove ipython
• sudo apt-get purge ipython
• sudo apt-get autoremove
• pip install jupyter

ipython seemed to be the problem, hence removing it fixed the issue.

[daming-lu]

@akashshah26595 Thanks! That works and helps me a lot!

[MARS2280]

@akashshah26595 You're great!

[amakukha]

pip install jupyter for some reason switched my conda environment to Python 3.7, disabling Tensorflow which was installed on Python 3.6...

[tamizharasank]

noo it's not working

[ptarun]

The error means that an executable called jupyter-notebook is not on your PATH. Since you are doing --user installs on macOS, scripts are going in $HOME/Library/Python/2.7/bin, which needs to be on your PATH and isn't by default. If that's the case, you can add it with:

export PATH="$HOME/Library/Python/2.7/bin:$PATH"

(In mac os x , open .bash_profile file in nano and paste this command to it.)

[iamtodor]

same to me: macos, updated to 3.7 and then rolled back to 3.6.5 python, but seems I have some link to python3.7:

mcbk:machine-learning todor$ jupyter notebook
Error executing Jupyter command 'notebook': [Errno 2] No such file or directory
mcbk:machine-learning todor$ jupyter-notebook
-bash: /usr/local/bin/jupyter-notebook: /usr/local/opt/python/bin/python3.7: bad interpreter: No such file or directory

I have done already pip3 uninstall jupyter && pip3 install jupyter
could you please help me?

[iamtodor]

Dunno how is it possible. the following command was running smoothly: python -m IPython notebook
why does it happen?

[averri]

Executing

sudo apt-get remove ipython
sudo apt-get purge ipython
sudo apt-get autoremove
pip install jupyter

... did not solve the issue. I'm using Ubuntu 18.04.

[hemangjoshi37a]

It seems to me as though the installation has messed up somehow. Try running:

For Python 2

pip install --upgrade --force-reinstall --no-cache-dir jupyter

For Python 3

pip3 install --upgrade --force-reinstall --no-cache-dir jupyter
This should reinstall everything from PyPi. This should solve the problem as I think running pip install "ipython[notebook]" messed things up.

[dboyliao]

@hemangjoshi37a
Thanks
It works for me.

[cabric]

@hemangjoshi37a
Great!
totally solved my problem

[hemangjoshi37a]

@cabric @dboyliao It's okay bros...
Awesome...

[rh314]

For me, on Windows, the jupyter-notebook script does not even get generated (searched my file system for it.)

I resorted to manually creating the following file and just running it:
_jupyer-notebook.py:_

#!/usr/bin/python3

# -*- coding: utf-8 -*-
import re
import sys

from notebook.notebookapp import main

if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0])
    sys.exit(main())

[jodobear]

I'm running Linux Mint 19 with python 3.6.6.
jupyter notebook gives me the same error: Error executing Jupyter command 'notebook': [Errno 2] No such file or directory

I tried both the solutions provided by @akashshah26595 :
sudo apt-get remove ipython sudo apt-get purge ipython sudo apt-get autoremove pip install jupyter

and @hemangjoshi37a
pip3 install --upgrade --force-reinstall --no-cache-dir jupyter

NONE of these solutions worked for me. I still get the same error and nothing else.

Can anybody please help me sort this out?

[deeenes]

@jodobear, have you got unable to uninstall distutils installed package error messages from pip3 install --upgrade --force-reinstall --no-cache-dir jupyter? If so you need to remove those packages manually and try pip3 install --upgrade --force-reinstall --no-cache-dir jupyter until it runs with no error.

[aqsa27]

Try jupyter-notebook
it will tell you to install
"sudo apt install jupyter-notebook"
now try "jupyter-notebook"
works fine

[PapaSmurf]

ubuntu 18: try as mentioned above,
$ pip3 install jupyter-notebook
then just
$jupyter-notebook

[mykolakozyr]

I had the same issue. While running @hemangjoshi37a command I've received the message that the directory packages being installed are not added to the Path.

I have added my python directory to the Path, ran mentioned
pip3 install --upgrade --force-reinstall --no-cache-dir jupyter
, and it worked.

[Vinod-Kumar-G]

It seems to me as though the installation has messed up somehow. Try running:

For Python 2

pip install --upgrade --force-reinstall --no-cache-dir jupyter

For Python 3

pip3 install --upgrade --force-reinstall --no-cache-dir jupyter
This should reinstall everything from PyPi. This should solve the problem as I think running pip install "ipython[notebook]" messed things up.

Thanks, it worked for me.

[pbraconnot]

On Mac OS High Sierra I had to disable SIP. Mac OS system protection that blocks modifications in certain /Library files.
To disable SIP restart holding command+R > Open Terminal > run command
csrutil disable
then
reboot
then hemangjoshi37a's saved my previously installed Python 3.7 and Anaconda for 3.7

pip3 install --upgrade --force-reinstall --no-cache-dir jupyter

[bharath5673]

i faced this same issue severely :( ,, and finally i found it alone ))) ///
and its all abt RANSOMEWARE PROTECTION on my windows 10 pro.. it wont let u over write any files and folder by third party apps under this protection.

1. • Open the Windows Security app by clicking the shield icon in the
     task bar or searching the start menu for Defender.
2. • Click the Virus & threat protection tile (or the shield icon on the left menu bar) and then click Ransomware protection.
3. • Set the switch for Controlled folder access to "OFF"

and happy jupyter)))

[Kasre96]

Had the same problem.
use jupyter-notebook instead of jupyter notebook

[lovezeropython]

what is the wrong?
➜ 3 time number jupyter notebook Error executing Jupyter command 'notebook': [Errno 20] Not a directory

[Vic-TheGreat]

For me to solve the problem. instead of installing jupyter with pip3 install jupyteras stated on the jupyter website

In terminal, simply do
pip3 install numpy

after
sudo apt-get install jupyter

then run
jupyter notebook
to launch jupyter.

Cheers!!!

[cybertron97]

Had the same issue: -
What I did : Try Locating Anaconda Navigator on your Mac using Spotlight Search,
Click -> Launch Jupyter notebook, Works perfectly on mine.
Also : Do the update afterwards : conda update conda, then just simply run jupyter notebook
Works Great now

[Julie-Von]

Same issue fixed for me by updating conda and reinstalling jupyter:

conda update -n base conda
conda install jupyter

Thaaaanks!!! This solves my issue.

[JECasillas]

Hi. Just a warning to everyone else. Using autoremove f**ing ruined my whole enviroment and it wasn't even the solution.
Now I have a bigger problem.
Thank you for telling people indiscriminately to use "Autoremove" like it was nothing and taking away our time.
Cheers.

[byronkats]

I am using ubuntu and i had tried all the solutions above, and they didn't work for me. I solved the problem using: sudo apt install jupyter-notebook

[vandesa003]

It is probably because you used an env of python. And in that env, the jupyter is not installed. Just reinstall jupyter in that env.

[xuejianma]

Try jupyter-notebook
it will tell you to install
"sudo apt install jupyter-notebook"
now try "jupyter-notebook"
works fine

works for me. Thx!

[MarkintoshZ]

For those who have tried all of the methods above and still have not get it to work, here is the solution for me:

python -m jupyter notebook
or
python -m jupyter lab
(use python3 or python3.6 instead of python if needed)

Good luck!

[saurabhprasadsah]

ipython notebook

open this command and use this

[saurabhprasadsah]

if you are using anconda then use this coomand
ipython notebook

[kpreeti096]

Try jupyter-notebook

yes sure this is running....

This is the only solution that works for me.

[saurabhprasadsah]

yeah sure...
This is working fine...

[kevin-bates]

There have been lots of great responses and sufficient success to warrant this issue's closure. Should others encounter this same issue and have applied the suggested tips, we can either reopen it or create a new issue (preferred). Thanks to everyone for helping out with this issue.

[jetcem]

For those who have tried all of the methods above and still have not get it to work, here is the solution for me:

python -m jupyter notebook
or
python -m jupyter lab
(use python3 or python3.6 instead of python if needed)

Good luck!

I appreciate for that, JupyterLab is working with that.
Should I open the JupyterLab always in this way? Could it cause any problem?

[saurabhprasadsah]

yes this is also working fine...
python -m jupyter notebook
(use python 3 and python3.6)
..

[OXPHOS]

Update the ipykernel package - it should be fixed by 4.7 or newer. ipython/ipykernel#278

Jupyter notebook stopped working once I logged out and logged in again.
This solution worked for me.
