After installing several python packages, I get following error when trying to launch Spyder from Anaconda. Not sure what I messed up during package install, but unable to remove it from Anaconda to install it back. Have tried --reset command as well to no avail.
Traceback (most recent call last):
File "C:\Users\USERNAME\Anaconda3\Scripts\spyder-script.py", line 10, in

Let me know how to fix the error so I that Spyder can be launched again from Anaconda without any errors.

I updated the anaconda Navigator and the Spyder.
But now when I try to launch it, there is the following message:

import textdistance
ModuleNotFoundError: No module named 'textdistance'
Can someone please suggest me what should I do
EDIT
I followed what "CanciuCostin" suggested in the comment.
And now I'm getting the following:
I tried conda install -c anaconda qtconsole and conda update qtconsole as well. But still the message is there.. :/
I had the same error today - with the last line about textdistance. I used conda to install text distance from the same environment as spyder and now I can open Spyder again.
conda install textdistance
My anaconda environment uses Python 3.
Well.. I used conda uninstall qtconsole and then once the uninstallation is complete, I installed it again by the command conda install qtconsole. But then I had to install spyder as well ( conda install sypder ).
Then it worked. But I had to install some libraries like scipy ( conda install scipy )
I am trying to work with my Jupyter notebook. I have done so for the last 6 six years or so. Now I am getting the following error message:
Python Anaconda ImportError No module named menuinst.knownfolders
I checked several posts on the internet but nothing has helped: “conda install menuinst”. see here:
Python Anaconda ImportError No module named menuinst.knownfolders
I now have uninstalled and re-installed it three times but did not solve the issue.
When I go to my anaconda prompt and type in “jupyter notebook”, these are the error message I am getting:

Just another piece of information, my anaconda prompt starts with (base) before it says C:\user\user>. Is that relevant or this issue?
You should try
conda remove zeromq
conda install zeromq
Solution-1
Please try to reinstall jupyter notebook from anaconda navigator it will definitely work
Solution-2
Please update jupyter notebook from anaconda prompt with below commands.
pip install notebook --upgrade
conda update notebook
I face the same issue..
1)Open anaconda prompt and type
conda list
2)Check terminado and
terminado 0.8.3
zeromq 4.3.2
3)In same anaconda prompt and check if python is working, type below code
python
if yes then
quit()
5)if no update python accordingly.
6)Type,
anaconda-navigator
This will open navigator and try to install jupyter notebook.
I'm implementing widgets in my jupyter notebook (via anaconda). I tried first by using an old code from a professor of mine, but it's not displaying widgets.
I tried installing:
jupyter labextension install #jupyter-widgets/jupyterlab-manager
But it was unsuccessful
This was presented when I attempted installation of the package via windows command prompt:
C:\Users\davio>jupyter labextension install #jupyter-widgets/jupyterlab-manager

I expect to:
i) Be able to install all the required ipy packages in order to display widgets properly
ii) View and manipulate widgets properly
Thank you!!!!
Maybe if you had alredy python installed before installing anaconda, that's the problem. Try uninstalling python and only working with anaconda's python, that worked for me.
(Sorry for bad english)
I went on to my computer today to work on a code I had been chiseling away at for school. I clicked on my anaconda navigator, only for anaconda to quickly show up in my running task bar at the bottom of my screen then disappear. I read on a other post that perhaps my Macbook wasn't updated and that was affecting it. I updated my Macbook and when I went to my launchpad to open Anaconda, it had completely disappeared. I tried opening a terminal and running "Anaconda-navigator" and I got this:
(base) xxxxx-MBP:~ xxxxx$ anaconda-navigator

I'm quite concerned, as my code was important for school and I can't access it. I tried installing it, but it said Anaconda was still downloaded, but it is nowhere to be found in my downloads or applications. Also, I ran the command to show my packages and they were still installed.
I installed Python 3.4 on my Windows 7 laptop several months ago as part of Anaconda (https://www.continuum.io/downloads). My installation included the Spyder IDE, and I have successfully been using Spyder for Python programming.
However, since yesterday, I have been unable to open Spyder. I typically open Spyder via the Start Menu, but now, when I try to click on the Spyder icon in the Start Menu, I get no response. I then tried to go directly to the spyder.exe file in the Scripts folder in the directory where Anaconda is installed. When I clicked on this the first time, the following message flashed quickly and then disappeared:
Traceback (most recent call last):
File "C:\Users\Aniket\Anaconda3\Scripts\spyder-script.py". line 2, in <module>

I double-clicked on Spyder.exe a second time, and this time, received the following message:

Both of these messages flashed very quickly and then disappeared - I captured them by quickly pressing Print Screen when they appeared. It's not evident to me what the error messages imply, nor what would have caused this. It's possible that I closed Spyder while some function was running, or that Spyder crashed and caused some persistent error. Does anyone know how I can fix this?
I had a similar problem of Spyder 2 not starting. My installation is part of Anaconda, on Win7 64-bit OS. I tried all the solutions outlined here and here, but they did not work for me. From the command line, I got the following error(s) when trying to reset spyder:
U:\>python -c "from spyderlib.spyder import main; main()" --reset

What surprised me was that spyder worked fine till yesterday, and I just did a full update yesterday as follows:
conda update --all
So I again updated spyder today with the following:
conda update spyder
And the following package plan was presented to me:
The following packages will be UPDATED:
spyder: 2.3.7-py35_3 None://None/<unknown> --> 2.3.8-py35_1
spyder-app: 2.3.7-py35_0 --> 2.3.8-py35_0
The following packages will be DOWNGRADED due to dependency conflicts:
matplotlib: 1.5.3-np111py35_1 --> 1.5.1-np111py35_0
pyqt: 5.6.0-py35_0 --> 4.11.4-py35_7
qt: 5.6.0-vc14_0 [vc14] --> 4.8.7-vc14_9
[vc14]
qtconsole: 4.2.1-py35_2 --> 4.2.1-py35_0
After the update, spyder works fine now.
In essence, my problem was due to dependency conflicts.
I ran into the same issue. The following worked for me
Please close Spyder IDE, in Anaconda Prompt run
conda update spyder
then
spyder --reset
Restart Spyder
Had the same exact problem as you a few days ago and reinstalling won't work so I went to:
C:\Users\'YourName'\\.spyder2-py3
delete every spyder, lock file/folder in it and relaunch.
I know this is an old thread but having just had the same problem an answer that worked for me from https://github.com/spyder-ide/spyder/issues/3005
My problem appeared to be that the status of spyder was still running so wouldn't open. To fix this you need to look for a directory called .spyder2 in your Users\ directory, then find a file called spyder.lock and remove it.
My solution:
I uninstalled Anaconda spyder
Removed all directories of it from
c: programs/
and c:users/Username/
and c:users/username/AppData/local
and c:users/username/AppData/
I downloaded a newer version of Anaconda Spyder and installed it.
It's all fine now.
You might get additional information if you run
from spyder.app import start
start.main()
as a python script. For example I got following output:
Traceback (most recent call last):

=> Maybe for Python 3.10 the import of collections needs to be fixed.
=> Try to use 3.9
I've got exactly the same error messages before, and I fixed it by installing spyder again under anaconda:
conda install spyder
Well it says it is missing PyQt4.dll, which you can check by: searching pyqt4 in your anaconda3 directory.
There are several possibilities:
it is still in: ~\Anaconda3_x86\Library\plugins\designer
That would mean python can't find since it ain't searching in this directory, I highly doubt that possiblity, since that would mean you'd have tweaked some code.
it ain't anywhere
Maybe you or more likely one of your programs did deleted it per accident?
it isnt in: ~\Anaconda3_x86\Library\plugins\designer
I also doubt this possibilty since it would mean the file has been moved...
However you can fix that by reinstalling spyder as mentioned by xuwei.
