Mac上刚安装的WebStorm或PHPStorm遇到SVN版本太旧的问题

Mac上刚安装的WebStorm或PHPStorm遇到SVN版本太旧的问题:

URL:	svn: E155021: This client is too old to work with the working copy at '/******/' (format 31). You need to get a newer Subversion client. For more details, see http://subversion.apache.org/faq.html#working-copy-format-change
Format:	1.8
Depth:	unknown

参考这位大侠的解决方法：

For developing WordPress with PHPStorm I seem to need Subversion 1.8 due to this notification:

Which shows this error:

It reads svn: E155021: This client is too old to work with the working copy at ‘/Users/andrea/dev/wp/vvv/www/wordpress-develop’ (format 31). You need to get a newer Subversion client. For more details, see http://subversion.apache.org/faq.html#working-copy-format-change.

Here they say

Now, IntelliJ IDEA offers different integration options for each specific Subversion:

1.6 – SVNKit only
1.7 – SVNKit and command line client
1.8 – Command line client only

If you opt to the command line client, make sure you have its binaries installed on your machine, because they are not bundled with IntelliJ IDEA.

So I checked my system:

$ svn --version
svn, version 1.7.17 (r1591372)
   compiled Aug  7 2014, 17:03:25
...

Then I installed Subversion all together using brew.

$ brew update
Updated Homebrew from 80f2d299 to 93e17517.
...

$ brew info subversion
subversion: stable 1.8.10 (bottled)
https://subversion.apache.org/
Not installed
...

$ brew install subversion

svntools have been installed to:

Bash completion has been installed to:
  /usr/local/etc/bash_completion.d
==> Summary

  /usr/local/Cellar/subversion/1.8.10_1: 116 files, 9,4M

It took some seconds to download and compile, but eventually I got:

$ svn --version
svn, version 1.7.17 (r1591372)
   compiled Aug  7 2014, 17:03:25
...

Uh?

$ which -a svn
/usr/bin/svn
/usr/local/bin/svn

OK, then I tried editing my ~/.bash_profile:

export PATH="/usr/local/bin:$PATH"

After which I had:

$ source ~/.bash_profile

$ svn --version
svn, version 1.8.10 (r1615264)
   compiled Aug 25 2014, 10:57:58 on x86_64-apple-darwin13.3.0
...

Then I closed PHPStorm and opened it again… But PHPStorm error didn’t go away !!

Then I searched PHPStorm preferences for “svn” and tried forcing/usr/local/bin/svn:

Which immediately made the error disappear:

So I undid the PATH change, just to be sure OSX still sees Subversion 1.7, and all is working fine.
