Problem Description

Spyder crashing upon startup.

I have just installed anaconda3 on this computer (a first time install), and updated anaconda and spyder to the newest versions. Initially it worked fine, but having forgotten numpy, I closed down, and installed it. When trying to open spyder4 again it would not work. I have restarted my pc, uninstalled and reinstalled anaconda and spyder a few times, and never have I gotten spyder to open again.

What steps reproduce the problem?

1. Fresh install of conda from website (64-Bit Graphical Installer for python 3.7)
2. In the conda prompt write conda update anaconda followed by conda install spyder=4.0.1
   (Note to 2: When updating anaconda it'll post some debugging lines, and when installing spyder it'll fail with initial frozen solve to solve the environment and commence debugging at the end - see screenshots for all)
3. Run spyder --reset
4. Launch spyder

What is the expected output? What do you see instead?

Pops up with the traceback instead of opening spyder.

Versions

• Spyder version: 4.0.1
• Python version: 3.7.4 (also tried 3.7.6 with no change)
• Qt version: 5.9.7
• PyQt version: 5.9.2
• Operating System name/version: Windows 10

Dependencies

I'm assuming this is if spyder is launchable - which it isn't for me. (cannot find this)

If you have Kite installed, please uninstall it. That should solve your problem.

@dalthviz, do you know what's happening in this case?

If you have Kite installed, please uninstall it. That should solve your problem.

When I first launched spyder (the time it worked) it asked if I wanted to install Kite, which I just accepted. The install failed and installer closed, and I thought nothing more of it. I cannot find kite using Window's add/remove programs feature, so I don't know if there are some files from it remaining from the failed install.

[dalthviz]

@ccordoba12 I'm not sure but maybe some how the failed installation make available the service that Kite uses while actually not being installed? Probably caused by remaining files of the failed installation that by pass the check of Kite being installed.

@Klumpfisk could you check if there is Kite related processes running in your machine? Also, could you try to download the installer manually (available here) and try to install Kite?. For example, when I run the installer I get the following message:

Edit: Reviewing the way we check if Kite is installed, we validate if the path C:\Program Files\Kite\kited.exe exists. @Klumpfisk could you try to check if you have a folder C:\Program Files\Kite and delete it?

[Klumpfisk]

Okay, so it seems kite has made a folder on my machine with that path, however it doesn't have an uninstaller. I get the same message when trying to install kite. I'll try to manually remove the folder and check it (I'll need to install a few things again as I reinstalled conda and used the 3.3.6 version of spyder)

[Klumpfisk]

Alright, that fixed it.
Thanks a lot, would've never found this on my own :)

[dalthviz]

Thanks for the patience to reinstall everything @Klumpfisk ! Glad you could make it work :)

[dalthviz]

@ccordoba12 maybe we need to add at least a message regarding failed installations and the need of a manual (or automatic) deletion of remaining files?

Definitely, please open a PR for that.

Hi, I have met the same problem. I tried to uninstall Kite before upgrading spyder. I found the first step of uninstallation of Kite is to uninstall plugins. The expected interface would be like this:

However what is shown on my PC is:

Plugins for Spyder is shown on the 'installed editor plugins' part but there is no uninstall button.

What should I do to uninstall the plugin?

[dalthviz]

Hi @1CoreBrain in your case, as Kite Copilot mentions, the thing is that you are using Spyder version 3.3.6. If you want to use Kite inside Spyder, please update to Spyder 4 which is the version that supports Kite (if you use Anaconda you can update running something like conda install spyder=4.0.1)

[ccordoba12]

@1CoreBrain, your problem was adequately answered by @dalthviz. Please don't add more comments on this issue about it because it's really unrelated to what @Klumpfisk reported initially.

Hi, sorry for that, I think I did not say it clearly.

My question is how to UNINSTALL Kite instead of using it.

The thing is when I want to UPDATE the Spyder to 4.0.1, I got EXACTLY what Klumpfisk has met, like:

And I was looking for help and found this discussion. As @dalthviz said, Kite should be uninstalled before updating Spyder. However, I met a problem when I was trying to uninstall Kite, which I have mentioned before.

Following the uninstallation step below, I need to uninstall the Spyder plugin first.

However, there is no UNINSTALL button when I try to uninstall the Spyder plugin, I even don't know whether it is installed.

Hence I wrote a comment on this issue because I meet the same problem as @Klumpfisk reported and met a problem when following the suggestion of @dalthviz.

[ccordoba12]

@1CoreBrain, please look at the directory shown in @Klumpfisk's last screenshot above and remove it.

Alright, thanks a lot. Spyder works again.
