The following are the key differences for a successful installation that
need to be executed at the end:
sudo mkdir -p /Library/Java/Extensions/libsvnjavahl-1.dylib
sudo ln -s /usr/local/Cellar/subversion/1.9.4/lib/libsvnjavahl-1.dylib /Library/Java/Extensions/libsvnjavahl-1.dylib
This step is very important. Many people say that javaHl is installed and they say that it cannot be used. Just do this again. According to the installation directory and version changes, my command:
sudo ln -s /usr/local/Cellar/subversion/1.9.5_1/lib /libsvnjavahl-1.dylib /Library/Java/Extensions/libsvnjavahl-1.dylib
Generally new machines do not have homebrew installed and need to be installed. Official documentation:
Get Homebrew:
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
I have installed this step several times. For specific commands, please refer to the official tutorial: https://brew.sh/index_zh-cn.html Open the terminal window and paste the above script. Homebrew will install the package into a separate directory and softlink the files to /usr/local.
