SVN同步、cleanup都会出现下面的提示：
svn: E155017: Can't install '*' from pristine store, because no checksum is recorded for this file
svn报错：“Previous operation has not finished; run 'cleanup' if it was interrupted“
解决：
一般的clean up报错，只要回到当前目录上一层进行clean up就能继续提交svn内容。但是，当回到最上层目录都无法clean up时，需要用sqlite3对工程目录下.svn/wc.db的数据库文件进行以下操作 ，步骤如下：
> sqlite3 PROJECT-ROOT\.svn\wc.db
> select * from work_queue ## 查看未完成的任务列表
> delete from work_queue ##
