SVN同步、cleanup都會出現下面的提示：
svn: E155017: Can't install '*' from pristine store, because no checksum is recorded for this file
svn報錯：“Previous operation has not finished; run 'cleanup' if it was interrupted“
解決：
一般的clean up報錯，只要回到當前目錄上一層進行clean up就能繼續提交svn內容。但是，當回到最上層目錄都無法clean up時，需要用sqlite3對工程目錄下.svn/wc.db的數據庫文件進行以下操作 ，步驟如下：
> sqlite3 PROJECT-ROOT\.svn\wc.db
> select * from work_queue ## 查看未完成的任務列表
> delete from work_queue ##
