There is an instance of anaconda navigator already running error

Question

Previously my anaconda navigator was not responding so I have rebooted my computer and now when I am trying to open anaconda navigator it pop-ups an error with "there is an instance of anaconda navigator already running".

OS: Windows 10

Solution 1

I met the same problem a few days ago. I found the anaconda navigator will start a process called pythonw. So the following is my solution:

1. open a cmd window;
2. use command tasklist | findstr "pythonw" to find the pid of pythonw, like 37200;
3. use command tskill 37200 to kill the process.

By the way, my OS is Windows.

Solution 2

I got the same error in MAC. logoff & login did not resolve the issue and the below command solved my issue in mac. Restart not required.

killall python

Solution 3

one of the following will solve your issue in ubuntu:

killall Anaconda-Navigator 

anaconda-navigator --reset

Solution 4

[With images] The instructions Below works flawlessly in Windows 10.

1. Run CMD (command prompt) with administrator privileges
2. Run the following command,

tasklist | findstr "pythonw"

3. Lastly, after identifying process ID run this command to kill the process,

taskkill /f /pid <PID NUMBER>
