svn cleanup failed because pristine file could not be moved

Question

I wanted to use svn cleanup to remove lock on my working copy but failed with the following log:

svn: E000001: Can't remove file '/Users/panjie/Desktop/work/SYS-SVN/.svn/pristine/e4/e41bbcb7a645255ae62c65613e6d0dcbe7499d70.svn-base': Operation not permitted

I checked the permission of the file and found nothing wrong. I am using SVN/1.9.3 under MACOSX/10.11.6

Answer 1

The cause of this is that the file is locked by macOS. So, the solution is simple chflags -R nouchg .svn and run svn cleanup again and everything is OK now.
