Issue: Versioning operations on the project at the command line, resulting in errors such as:
Svn:E155021:This client is too old to work with the working copy at
'/users/user/works/v1baobao4iphone ' (format 31).
You need to get a newer Subversion client. For more details, see
Http://subversion.apache.org/faq.html#working-copy-format-change
Cause: The SVN version on the command line is 1.7.17, and the SVN client version I used is 1.8.x, and after using the high-version operation in the SVN client, I go back to the command line and take a break.
Workaround: As stated above, use the official script available to handle it. But the next time you're not paying attention and working on the client, you have to. Once and for all, upgrade the SVN version below the command line to the new version.
First go to download the new Mac version of Mac OSX 10.10-yosemite-subversion 1.8.11
Fool installation, after installation to pay attention to, this time need to manually add the new SVN path to the environment variable, in fact, the installation program itself will prompt, look at the picture
$CD ~$sudo vim. Bash_profile the export PATH=/opt/subversion/bin: $PATH added to the end of the file, save and exit $ source. Bash_profile
Now use SVN--version to see the SVN version.
Mac OSX 10.10-yosemite Update svn version
