Standard Standalone Installation? (y/n) If not then what?: y

What are you trying to achieve?:

I am trying to update a plugin. The developer team of the plugin advised me to:

  1. Close all psychopy windows
  2. Find and delete the entire .psychopy3 folder at C:\Users\xxx\AppData\Roaming\psychopy3
  3. Launch PsychoPy builder and install the plugin from the Plugins/Packages window (from the Tools menu)
  4. Close all PsychoPy windows and launch once more.

I have done the same thing a few times before and it has always been working fine. But this time I am getting a “could not retrieve plugins. Try restarting the psychopy app and make sure you are connected to the internet” when I open plugin/packages manager from the Tools menu.

I’m pretty sure I have a good internet connection. Is this an issue on my end or is it something related to your server? Thank you in advance!

I have tried on two different computers and with different network and I’ve been getting the same issue

I installed Psychopy on a new computer that has never had Psychopy before and I am getting the same error when I open plugins/package manager. Any help is appreciated! Thank you!

Deleting the entire .psychopy3 folder seems a bit drastic.

Plugins have improved since 2024.2.1. Are you able to update?

Hi,

I had the same problem and solved it by running Psychopy (v.2024.2.4) with admin rights.

Hope it works :slight_smile:

There are clearly still issues around the ability to index/search the pypi projects list. We are working on a fix so that you can still install the plugins (psychopy packages that are known to us) can be installed as well as any packages that you know the names of.

If you already know the name of the name of the package you want then the current workaround is to do this from PsychoPy’s Python shell (the Shell panel in the Coder view):

>>> from psychopy.tools import pkgtools
>>> pkgtools.installPackage( 'name-of-my-package' )
