You need to run the cmd prompt from the Scripts directory of Anaconda where ever you have the Anaconda parent folder installed. I happen to have in the root directory of the C drive on my Windows machine. If you are not familiar there are two ways to do that:
A) Use the key combination Win-key + R then type cmd and hit return to launch the terminal window and then type: cd C:\Anaconda\Scripts (or whatever directory path yours is).
B) Navigate using windows explorer to that Scripts directory then type cmd in the address bar of that window and hit return (that will launch the terminal already set to that directory).
Next type the follow commands waiting in between for each to complete:
activate root
conda update -n root conda
conda update --all
When complete type the following and Navigator hopefully should launch:
anaconda-navigator

You need to update Anaconda using:
conda update
and
conda update anaconda-navigator
Try these commands on anaconda prompt and then try to launch navigator from the prompt itself using following command:
anaconda-navigator
If still the problem doesn't get solved, share the anaconda prompt logs here if they have any errors.

I am not sure why but the command below worked for me.
pip install pyqt5
Of course I updated Anaconda and Navigator before running this command.
回答4:
I had the same issue, and solved it by the following commands:
conda update conda
conda update anaconda-navigator
anaconda-navigator --reset
anaconda-navigator
回答5:
I had the same problem which was mainly due to an update to PyQt5, the following code helped me.
Run cmd.exe as admin:
conda update conda
conda update anaconda-navigator
reinstall PyQt5:
pip uninstall PyQt5
pip install PyQt5
pip install pyqtwebengine
回答6:
Faced the same problem. 'conda update' does not work; It gives the error : "CondaValueError: no package names supplied"
On executing the following commands, I was able to launch the Anaconda navigator:
conda update -n base conda
conda update anaconda-navigator
回答7:
I was also facing same problem. Running below command from conda command prompt solved my problem
pip install pyqt5
回答8:
This helped to me:
conda install anaconda-navigator
回答9:
Update to the latest conda and latest navigator will resolve this issue.
Open the Anaconda Prompt and type
- conda update conda
and
- conda update anaconda-navigator

I was working on my Windows 10 machine and I'm not sure which package "broke" Spyder and Anaconda Navigator, but could have been either, or, or both Kivy-1.10.1 and moviepy-0.2.3.5 which gave me problems. I installed with either pip or conda. So of course I looked on this site to see what to do to fix. I found how pyqt was probably the issue. I uninstalled pyqt, kivy, and moviepy by using "pip uninstall ". I found where/or how they were installed by "pip list" and "conda list". After they were uninstalled I used "conda install - c anaconda pyqt" to reinstall pyqt. After installing pyqt I launched Spyder with no problems.

I tried the following @janny loco's answer first and then reset anaconda to get it to work.
Step 1:
activate root
conda update -n root conda
conda update --all
Step 2:
anaconda-navigator --reset
After running the update commands in step 1 and not seeing any success, I reset anaconda by running the command above based on what I found here.
I am not sure if it was the combination of updating conda and reseting the navigator or just one of the two. So, please try accordingly.

I struggled with this problem for a couple of hours (got the same error message you showed in your attachment). I knew the problem had to do with the path variable, specifically the PYTHONHOME variable.
I finally found I had set the PYTHONHOME path to the python.exe file (C:\Anaconda3\python.exe). It should be set to the Anaconda folder that contains the python.exe file (C:\Anaconda3).
After that I could run the Anaconda Navigator.
回答13:
For me it worked doing this:
Uninstall the previous version: go to C:\users\username\anaconda3 and run the anaconda-uninstall.exe
Install again anaconda
then run the following commands on the anaconda pompt:
conda create -n my_env python=2.7
conda activate my_env
start the gui app
anaconda-navigator
