macOS Catalina

I had the same issue after upgrading to Catalina 10.15. It's clearly mentioned in the Apple website that SVN is deprecated in Xcode 11:

You can find it here: https://developer.apple.com/documentation/macos_release_notes/macos_catalina_10_15_release_notes

Command line tool support for Subversion — including svn, git-svn, and related commands — is no longer provided by Xcode.

The solution is to install the standalone Command Line Tools package instead:

sudo rm -rf /Library/Developer/CommandLineTools

followed by:

sudo xcode-select --install

This will replace the bundled Command Line Tools with the standalone package.

If it doesn't work for you then try to install it with brew.

brew install svn

brew is a package manager for MacOS so if you don't have it installed then you can simply install it: https://brew.sh/

macOS Big Sur

I faced the same issue Today (16th November 2020) after upgrading to MacOS Big Sur. I was able to fix it by installing the SVN again using brew install svn command.

If you faced permission errors after running above command, you can fix it by running following command.

sudo chown -R $(whoami) /usr/local/*

brew install svn 

in Xcode 11.4. Svn has been removed.

I had same issue from Netbeans and have done the following from command line and now all fine

sudo xcode-select --install

1. /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
2. brew install svn

Coming from a FreeBSD background we elected to install SVN via MacPorts which is akin to FreeBSD Ports. So basically one would first need to install MacPorts and then install SVN as follows:

sudo port install subversion

Some details -

1. Install MacPorts: https://www.macports.org/install.php

2. Install SVN: https://trac.macports.org/wiki/howto/Subversion

It took less than five(5) minutes and works well for us.

I switched to SVNKIT which works very well for my purposes. Since I'm doing a lot of Java development is no drawback for me that SVNKIT is based on Java. The big advantage is that SVNKIT will still work even if Apple throws SVN out completely.

I found svn still available on my Mac (upgraded from 10.15.x -> Big Sur, including XCode upgrade) in

/Library/Developer/CommandLineTools/usr/bin/svn

In the Apple Developers forum I read the suggestion to make an alias, which worked for me. However, considering svn is being dropped by Apple, this will probably not work on new installs, but it could be useful for those of us that just want it to work for now after upgrading.

alias svn=/Library/Developer/CommandLineTools/usr/bin/svn

Note: I found it easier to just make a symbolic link to svn:

ln -s /Library/Developer/CommandLineTools/usr/bin/svn /usr/local/bin/svn

my mac os version is macOs Catalina 10.15.5,I try

sudo rm -rf /Library/Developer/CommandLineTools
sudo xcode-select --install
brew install svn 

but it not work.so I try to install with source code.It's work!

tar xvf subversion-1.14.0.tar.gz
cd subversion-1.14.0
./configure --with-apr=/usr/local/opt/apr --with-apr-util=/usr/local/opt/apr-util
make

now,you can find it in /usr/local/bin/

Based partly on the other answers here, I built from source with this procedure:

1. Download & unpack svn source tarball (NOT zip file!) from https://subversion.apache.org/download.cgi
2. cd subversion-1.14.0
3. ./get-deps (this seems to have downloaded apr and apr-util but not built them)
4. cd apr
5. sudo mkdir /usr/local/opt (because I did not already have such a directory on a fresh Mac)
6. ./configure --prefix=/usr/local/opt/apr
7. make
8. make test (saw lots of "OK" and "SUCCESS", plus one failure in "testsock")
9. sudo make install
10. cd ../apr-util
11. ./configure --prefix=/usr/local/opt/apr-util --with-apr=/usr/local/opt/apr
12. cd ..
13. make
14. ./configure --with-apr=/usr/local/opt/apr --with-apr-util=/usr/local/opt/apr-util --with-lz4=internal --with-utf8proc=internal
15. make
16. sudo make install

The top instructions (removing the command line tools, xcode-select --install, and brew install svn) worked for me (Monterey, 12.5.1, on an M1 pro). Thanks! However, after I did the brew install, I had to manually remove the old svn version from /opt/local/bin before the new version would run. (discovered with $ which svn). Might be the result of migrating from the old laptop to the new one.
