错误看起来像：
subversion/libsvn_wc/revision_status.c:64: (apr_err=155036)
subversion/libsvn_wc/wc_db.c:12132: (apr_err=155036)
subversion/libsvn_wc/wc_db_wcroot.c:573: (apr_err=155036)
subversion/libsvn_wc/wc_db_wcroot.c:301: (apr_err=155036)
subversion/libsvn_wc/upgrade.c:1551: (apr_err=155036)
svn: E155036: Working copy '/Volumes/(some path)' is too old (format 10, created by Subversion 1.6)
output of svnversion -n is:
Command /bin/sh emitted errors but did not return a nonzero exit code to indicate failure
尽管如此，我仍然可以编译和执行/调试我的项目，但必须在某个地方摆脱这个错误......提前谢谢你！
