RuntimeError: Failed to disconnect signal currentIndexChanged(int)

[CarlosAMosquera]

Actual Behavior

The navigator launches but Anaconda3 Individual edition does not launch at all in Windows 10 X-64.

Expected Behavior

There is an error but I cannot fix it. The starting icon is shown but the program stalls and does not launch the GUI.

Steps to Reproduce

I installed Anaconda (run) as Administrator in Windows 10 X64. Installation steps

• Install for: All users
• Destination Folder: C:\ProgramData\anaconda3.
• Advanced Options: Register Anaconda3 as my default Python 3.7

I run the Anaconda Prompt (with Administrator permissions) the following: anaconda-navigator Errors that appear to me:

• ModuleNotFoundError: No module named 'PySide'
• PythonQtError ('No Qt bindings could be found') qtpy.PythonQtError: No Qt bindings could be found

I proceed to install PySide: pip install PySide2 Successfully installed: Successfully installed PySide2-5.14.2.1 shiboken2-5.14.2.1

Within the environment variables, in system variables I have configured the following: Variable: Path Value: C: \ ProgramData \ anaconda3 \ Lib \ site-packages \ PySide2 \

Variable: QT_PLUGIN_PATH Value: C: \ ProgramData \anaconda3 \ Lib \ site-packages \ PySide2 \ plugins

OR after installing PySide2, you actually replace the plugins with the ones from PySide2: Copy ...\Anaconda3\Lib\site-packages\PySide2\plugins\platforms\qminimal.dll ...\Anaconda3\Lib\site-packages\PySide2\plugins\platforms\qoffscreen.dll ...\Anaconda3\Lib\site-packages\PySide2\plugins\platforms\qwindows.dll (actually all files) files to ...\Anaconda3\Library\plugins\platforms\

I reset the navigator successfully (anaconda-navigator --reset) and run anaconda-navigator (anaconda-navigator) again from cmd. From desktop icons, the behavior is the same, just that I cannot interrupt the execution due to the error. In cmd, you just type ctrl+C and interrupt the error.

Output of conda info

I see the Anaconda icon, when it starts to load the applications it appears to me:

Message: (base) C:\WINDOWS\system32>anaconda-navigator
Traceback (most recent call last):
  File "C:\…\anaconda3\lib\site-packages\anaconda_navigator\widgets\main_window.py", line 541, in setup

    self.combo.currentIndexChanged.disconnect()
RuntimeError: Failed to disconnect signal currentIndexChanged(int).

I hope you can help me.

i got the same issue, but i haven't added anaconda to path

[AlphaLabs2302]

The solution is to open anaconda prompt and type in 'pip install spyder' then they will install the missing packages and fix the issue

@AlphaLabs2302 - That didn't solve my problem. I have the exact issue on windows 10 - 64 bit Anaconda and does anyone have a fix ?
