==>Pouring subversion@1.8-1.8.19.sierra.bottle.tar.gz
==>Caveats
svntools have been installed to:
/usr/local/opt/subversion@1.8/libexec
This formula is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.
If you need to have this software first in your PATH run:
echo 'export PATH="/usr/local/opt/subversion@1.8/bin:$PATH"' >> ~/.bash_profile
For compilers to find this software you may need to set:
LDFLAGS: -L/usr/local/opt/subversion@1.8/lib
CPPFLAGS: -I/usr/local/opt/subversion@1.8/include
Bash completion has been installed to:
/usr/local/opt/subversion@1.8/etc/bash_completion.d
==>Summary
🍺 /usr/local/Cellar/subversion@1.8/1.8.19: 128 files, 9.2MB
localhost:~ zhangxiaofei$
4, 执行 echo 'export PATH="/usr/local/opt/subversion@1.8/bin:$PATH"' >> ~/.bash_profile 然后 source .bash_profile。
最后查看SVN版本 svn --version svn, version 1.8.19 (r1800620)降级成功！
