解决WebStorm 中集成svn时出现的路径错误问题

在webstorm中集成svn的时候出现了一个问题，webstorm报错"Can't use Subversion command line client: svn The path to the Subversion executable is probably wrong."。
很久以前在Android studio中集成svn的时候也遇到过类似的问题，把解决问题的方法记录下来。

This is annoying, I wish IntelliJ would handle this better than a startup nag..
If you are using TortoiseSVN 1.8+ on Windows, do this:
1. Run the the TortoiseSVN Installer. (It may still be in your Downloads folder)
2. Select the option to Modify.
3. Install Command line client tools on to the local harddrive.
4. Add C:\Program Files\TortoiseSVN\bin to your Path environment variable.
5. Restart IntelliJ.
