报错1：执行cleanup 失败，报错如下
Cleanup failed to process the following paths:
Failed to run the WC DB work queue associated with
can't intall'###'from pristine store,
because no checksum is recorded for this file
解决方式：使用SQlite
下载https://www.sqlite.org/download.html
分别解压，把文件都拷贝到.svn 目录下
双击sqlite3，输入.open wc.db
输入 select * from work_queue;
输入 delete from work_queue;
输入.exit
OK！可以执行cleanup 和update了！！
