Programming Help

Because Xcode do not provide svn we need to install it

  1. a nice way to do it is to install the brew environment
    /bin/bash -c “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)”

  2. then install svn
    brew options subversion
    brew install subversion

  3. under matlab
    DownloadPsychtoolbox

There have been some other posts about this on the forum the last two weeks, please have a look there

Thanks Diederick for the hint.

Unfortunately I have installed Xcode on Catalina and svn is no longer accessible with this version.
As suggested via the forum I tried to reinstall Xcode

sudo rm -rf /Library/Developer/CommandLineTools
sudo xcode-select —install

And insert /usr/bin/svn in Matlab path

But always the fatal message « Sorry, the download command “CHECKOUT” failed with error code 72:

svn: error: Failed to locate 'svn’. »

any suggestions ??
