Anaconda won't update spyder 4

Question

I just installed Anaconda and haven't changed anything. When I start spyder3 it tells me spyder 4 is available. So I decided to update it. I tried

conda update  --all

conda update conda

conda update spyder

.

It all gave no errors, but when I start spyder it's all fine. I know this should work because I already did this in the past. Every help very appreciated.

Answer 1

What worked for me was clicking the "remove application" option in the settings in the top left corner of Spyder on the Anaconda Navigator. Once I removed it, it gave me an option to reinstall the newest version of Spyder.

You may have to do the commands above (for example, conda update --all) to "unlock" the newer versions after removal, though.

Answer 2

The following methods work for Anaconda Navigator 2.0.4 (Mac).

Update Anaconda Navigator

Go on the Anaconda Navigator and click on the gear on the top right corner of the Spyder "icon".

Click Remove.

Wait a couple of minutes for it to remove.

Then click refresh (if doesn't refresh automatically).

Spyder should reappear and the latest version should be suggested for installation. However, click again on the gear, install version-specific, and select the desired version.

If it doesn't work, remove Spyder again, open Terminal, and enters:

conda update anaconda
conda install spyder=5.0.5

Answer 3

Same problem , i have an environment with Spyder 3.3.1 when i try update from command line says it's already installed. have tried
conda update -n $ENV_NAME spyder
conda update spyder

when i try and update it through anaconda navigator it says "all requested packages already installed" but it hasn't it still remains as version 3.3.1

Worked out that i had to upgrade to python 3.6 at least. but had a lot of trouble doing that with all the existing dependencies.

finally i just created a new environment with 3.7 and spyder 4.3, so not ideal but at least it works
