I installed python and jupyter notebook through the Anaconda distribution. I have been successfully using jupyter notebook for weeks and it has run perfectly fine. However, I can only launch a notebook through the Anaconda Navigator GUI.

When I try to run the command (in command prompt) to start a notebook it says

'jupyter' is not recognized as an internal or external command

This is also the same case with Python

'python' is not recognized as an internal or external command

I am using Windows 10. I am assuming its a PATH issue but I have not had any luck with the solutions I found from other posts. I am relatively new to programming and python so any help would be greatly appreciated.

  • Do you have anaconda prompt installed? Then you can use python or jupyter there. Commented Sep 12, 2018 at 3:46
  • possibly try using choco package manager. I still had issues installing jupyter so I ended up using a Cloud VM ( AWS -> EC2 - use the free tier AMI ). doco. tutorial Commented Sep 12, 2018 at 3:49
  • so both python and jupyter notebook are installed in your conda environments that your command prompt can't locate. If you don't mind you could install them again (not in anaconda), otherwise you need to run them inside anaconda prompt as Kota suggested. Commented Sep 12, 2018 at 4:08
  • Probably not in your path. Windows or Unix? Check your path and see if the jupyter install location is in the path. Commented Sep 12, 2018 at 6:39
  • @KotaMori I am trying to run "jupyter" from Anaconda prompt and I get "not recognized" error Commented Oct 29, 2019 at 12:28

Yes, This is the problem which I faced also during the installation of Jupyter Notebook. But I know the solution of this. I hope, it also works for you as well.

  1. Open cmd.
  2. Type: pip install notebook.
  3. If you Type: **jupyter notebook** - it always shows an error.
  4. So, Type: python -m notebook.

Did the "pip install notebook" and succeeded and then "python -m notebook" but got "python.exe: No module named Notebook"
First, pip install jupyter notebook then, python -m notebook worked for me.
python -m jupyterlab worked when I ran into the same issue in VSCode/Win10

I've just fixed this issue on my windows 10 machine. My path contained

C:\Users\user\AppData\Local\Programs\Python\Python37\Scripts\

where 'user' is my windows username, however for some reason jupyter.exe installed in

 C:\Users\user\AppData\Roaming\Python\Python37\Scripts

I'm not really sure why and I'd like to get to the bottom of it, but adding both the local and roaming version to my path fixed this.

Where to check the path?
8

The issue 'jupyter' is not recognized as an internal or external command is mainly due to no path or wrong path of jupyter in windows environment variables.

In my case related files were available in C:\ProgramData\Anaconda3\Scripts and so i have added this path in Windows as shown below and then you can run from any path:

enter image description here

One important thing: after that while running jupter notebook from any location may give DLL Error. You have to first give command activate base and then jupyter notebook. Enjoy working now.

Run conda install ipykernel in that environment and then type jupyter notebook, it will lead to jupyter notebook window.

If you are facing the issue with the error as below when trying to launch jupyter notebook:

jupyter : The term 'jupyter' is not recognized as the name of a cmdlet, function, script file, or operable program.

Try using below command in TERMINAL:

python -m notebook

I recently faced this problem and overcame it by below following the command.

If you installed Jupyter Notebook through Commandline or Anaconda. for Windows 10

First check how your Python is running in command using

Using this command

C:\Users\admin>py

or this command

C:\Users\admin>Python

Most probably your Python starts with the py command.

Now type the below command to run Jypyter

C:\Users\admin>py -m jupyter notebook

or try

C:\Users\admin>python -m jupyter notebook

It'll start jupyter notebook on the browser.

Make sure to add the complete name jupyter notebook. It's working with Windows 10

I hope it helps.

Hi @Chandra, could you please elaborate on the answer you provided? Which check boxes it needs to be checked?
@ toshiro92 I think he's talking about the checkboxes which appear when we install Anaconda. But I checked both of them still the same problem arised

Here is a supplementary suggestion with respect to @Subhasish Paul 's Answer:

When creating a new path to the user variable (if you chose the option "install for all users" you may need to create a system variable), also include another path of "bin" in your environment variables, simply entering where conda in Anaconda Prompt to look for it. For me it's C:\ProgramData\Anaconda3\Library\bin .

Adding this extra path in your environment variables will eliminate DLL Error, hence you don't have to activate conda each time when you want to open jupyter notebook. It works for me very well.
