I use svn in a terminal window.
When I have updated my OS to Catalina 10.15.5,
the svn was not available anymore.
the message is:
svn: error: Failed to locate 'svn'.
svn: error: The subversion command line tools are no longer provided by Xcode.
I followed the procedure given by apple:
sudo rm -rf /Library/Developer/CommandLineTools
xcode-select --install
but it did not work.
I think that it is a trouble with Xcode, but I do not know what to do. Can I have help ?
