Hi! I’m trying to install psychtoolbox but it always fails with an error code 72 (see bellow)
BUT I do have svn last version installed (I installed it via homebrew and checked in my terminal if it’s correctly installed which it is) and Xcode uninstalled since the last version didn’t support svn anymore. So I don’t really get why it keeps telling me the error is with svn no longer provided by Xcode…
DownloadPsychtoolbox
DownloadPsychtoolbox(‘/Applications’,‘beta’,‘’)
Requested flavor is: beta
Requested location for the Psychtoolbox folder is inside: /Applications
Will use the svn client which is located in this folder: /usr/bin/
Good. Your privileges suffice for the requested installation into folder /Applications.
I will now download the latest Psychtoolbox for OSX.
Requested flavor is: beta
Target folder for installation: /Applications
The following CHECKOUT command asks the Subversion client to
download the Psychtoolbox:
/usr/bin/svn checkout https://github.com/Psychtoolbox-3/Psychtoolbox-3/branches/beta/Psychtoolbox/ “/Applications/Psychtoolbox”
Downloading. It’s nearly 100 MB, which can take many minutes.
Alas there may be no output to this window to indicate progress until the download is complete.
Please be patient …
If you see some message asking something like “accept certificate (p)ermanently, (t)emporarily? etc.”
then please press the p key on your keyboard, possibly followed by pressing the ENTER key.
svn: error: The subversion command line tools are no longer provided by Xcode.
Sorry, the download command “CHECKOUT” failed with error code 72:
svn: error: The subversion command line tools are no longer provided by Xcode.
The download failure might also be due to temporary network or server problems. You may want to try again in a
few minutes. It could also be that the subversion client was not (properly) installed. On Microsoft
Windows you will need to exit and restart Matlab or Octave after installation of the Subversion client. If that
does not help, you will need to reboot your machine before proceeding.
Another reason for download failure could be if an old working copy - a Psychtoolbox folder - still exists.
In that case, it may help to manually delete that folder. Or maybe you do not have write permissions for the target folder?
