I installed the latest version of Anaconda (2022.10-Windows-x86_64) and the navigator isn't launching. When I click the shortcut in my Start menu, or if I start the application directly from the application, the command window pops up for an instant then disappears and that's about all that happens.
When I launch the Anaconda prompt, I get an immediate error message that says "Invoke-Expression : Cannot bind argument to parameter 'Command' because it is an empty string."
See screen shot:
I get the same error message if I enter any command. Jupyter and Python both launch and work, but navigator does not and I cannot install any packages or dependencies. Any thoughts?

I am trying to make a python project that requires detection of keys from the user, I have tried installing the python package keyboard by running pip3 install keyboard in cmd, it ends up installing the keyboard package but when I type import keyboard into python and run the project it keeps showing an error message of: No module named 'keyboard', even though I installed it.
I am using python 3.10.4 on windows 10 home.
I use spyder as my programming editor.
I have tried uninstalling python and re-installing it but that didn't work. I have tried uninstalling the module and re-installing it but that didn't work. I have tried repairing python but that didn't work.

I managed to solve this problem by downloading and installing miniconda: (https://docs.conda.io/en/latest/miniconda.html)
I then searched for anaconda prompt in the windows search bar,
then I created a new environment using the command conda create -n spyder2 python=3
instead of spyder2 you can name it what ever you want.
Then I activated the environment by using the command conda activate spyder2
replace spyder2 with your chosen environment name.
Then I added the necessary spyder-kernels by using the command..
pip install spyder-kernels
Then I added my chosen package which in this case was the keyboard package, I used the command pip install keyboard replace keyboard with your own package name.
You can now close the anaconda prompt by pressing the exit button or typing exit in the prompt.
You now want to open spyder and click on the tools tab at the top of spyder, now press the preferences in the drop down menu when shown, then click on python interpreter in the list of options when shown, under the python interpreter section click the second check box, then click on the drop down menu and select the environment that you had made in the anaconda prompt, then click the apply button located at the bottom and then click the ok button located next to the apply button.
Now restart spyder and you have finished creating your new environment and can now start using 3rd party packages and modules.
Note: If you are wanting to add new packages or modules, open the anaconda prompt and activate the environment that you had just made using the code provided earlier on in this tutorial, then use the pip install YourPackageNamecommand and your done.
I have installed anaconda from its official website but I am not able to access launch jupyter notebook or any other application using the anaconda navigator. First, the navigator shows me to install, when I click on the install option it gives me an environment location not found error(check attached image).
after clicking ok on the error, it shows the option to launch but doesn't work, loads for some time and then nothing happens. I can access the jupyter notebook using the command prompt but I wanna know that why its not working through the navigator. Also, I am not able to change the theme of the notebook even after installing jupyterthemes using pip. I wanna that work too.

I have the lat4est version of Anaconda, Python v3.8 installed on my system running on Windows 10 Pro. I have not installed Anaconda in the default drive but set the path for Python, conda to the installed drive. But in spite of doing everything right as it seems, the Jupyter notebook is not opening when launched from the Anaconda Navigator but opens fine when I type the command from the Windows command prompt. None of the applications displayed in the Anaconda Navigator open and remain stuck as seen in the screenshot attached. But these applications do open when executed independently from the Windows Start menu.
Hope you understand the issue and respond to what may be the issue that makes the Navigator work improperly. I have already reinstalled many times but the issue persists.
Not sure about the applications not launching, but you can try going to Environments in the navigator, then click launch (looks like a play button) and "Open with Jupyter Notebook". This one works for me.
P.s. choose the environment you are looking for. If you did not create any additional envs, choose 'base'.
I'm a beginner in machine learning so tried installing ANACONDA after the complete installation as the tutorial shows it doesn't ask me to install VS code.
That's not issue I can download it separately but I cant find the anaconda navigator.
when I open the anaconda prompt it shows activate.bat is not recognized as internal external command can you please help me if you know what is the problem.
I'm struggling in this issue from past 3 days... reinstalled countless time. Tried installing miniconda.
After installing still navigator doesn't appear.
But Promt works fine here so can run commands to install the navigator.
When the navigator gets installed I cant launch any apps like Jupyter notebook or spyder.
It shows Spyder Crashed.
Any help is appreciated.
Procedure that I followed.
1) Installed Anaconda
2) I did not find Navigator nor did the anaconda promt start it shows activate.bat is not recognized as internal external command.
3) So uninstalled anaconda and installed Miniconda in this anaconda prompt works fine but navigator wasnt there so i followed this post
Anaconda Installed but Cannot Launch Navigator
4) Then I could use the navigator and while I try to launch the spyder or the jupyter it throws error saying spyder crashed during last session
Can anyone help?
I am running Windows 10 with Anaconda 3. I attempted to get to the Anaconda Navigator through clicking on navigator app in Explorer (Anaconda3\pkgs\anaconda-navigator-1.8.7-py36_0) but that only brings up a flash of what I assume is the command window (because it's too fast to see) and then nothing happens.
I can use the Anaconda prompt and so I tried running navigator using 'anaconda-navigator' and it gives error line:
".....is not recognized as an internal or external command, operable program or batch file."
I tried typing 'jupyter notebook' into the command line but the message is:
Error executing Jupyter command 'notebook': [Errno 'jupyter-notebook' not found] 2
This has happened multiple times with me uninstalling and reinstalling Anaconda. How do I fix this as it seems to be a serious problem as almost nothing works?
For starters I would check the environment path.
if you go in the application folder, where the exe or run program is, can you start it?
Is there a bin folder? See if you can start Anaconda in debug mode.
this might help: http://anaconda-installer.readthedocs.io/en/latest/boot-options.html
I would first look to see whether anaconda-navigator and jupyter-notebook are installed in your environment through the command conda list at your anaconda prompt.
If they are missing just install them through conda install anaconda-navigator jupyter-notebook
Generally, i would execute the command conda install anaconda anaconda-navigator jupyter ipython just to be sure that no packages are missing from your environment.
Hope this helped. :)
To run anaconda-navigator:
$ source ~/anaconda3/bin/activate root
$ anaconda-navigator
