svn使用过程中遇到的错误

本人的svn环境在MAC下，最近遇到了一些奇怪的错误，导致项目更新失败。

1.

svn: E155009: Failed to run the WC DB work queue associated with '/Users/mining/project/android', work item 9632 (file-install ruifeng_chcv/settings.gradle 1 0 1 1)
svn: E155017: Can't install '/Users/mining/project/android/ruifeng_chcv/settings.gradle' from pristine store, because no checksum is recorded for this file

解决:
miningdeiMac-3:android mining$ cd .svn  （找到.svn文件并进入）
miningdeiMac-3:.svn mining$ sqlite3 wc.db "select * from work_queue"

9632|(file-install ruifeng_chcv/settings.gradle 1 0 1 1)
9633|(file-install ruifeng_chcv/gradle/wrapper/gradle-wrapper.jar 1 0 1 1)
9634|(file-install ruifeng_chcv/gradle/wrapper/gradle-wrapper.properties 1 0 1 1)

miningdeiMac-3:.svn mining$ sudo sqlite3 wc.db "delete from work_queue"
---重新更新项目，一切正常。

2.
miningdeiMac-3:lib_mipcu mining$ svn up
Updating '.':
svn: E000013: Unable to create pristine install stream
svn: E000013: Can't create temporary file from template '/Users/mining/project/android/.svn/tmp/svn-XXXXXX': Permission denied
解决：
miningdeiMac-3:lib_mipcu mining$ cd ..
miningdeiMac-3:commonLibs mining$ cd lib_mipcu
miningdeiMac-3:lib_mipcu mining$ sudo svn up（加权限）—check if you have the permission of /var/www/html/mysite/
Password:

附：对整个文件夹加可读可写权限：

miningdeiMac-3:project mining$ sudo chmod -R 0777 android
