为什么一直报错啊？

为什么一直出现如下提示啊？
rm failed for /mnt/sdcard/Android/data/io.dcloud.HBuilder/.HBuilder/apps/HBuilder/www/, Permission denied
mkdir failed for /mnt/sdcard/Android/data/io.dcloud.HBuilder/.HBuilder/apps/HBuilder/www/, Permission denied
同步失败，失败原因：failed to copy 'D:\My Documents\HBuilder.windows.5.8.2\HBuilder\configuration\org.eclipse.osgi\bundles\77\data\run_tmp/audio/shake.wav' to '/mnt/sdcard/Android/data/io.dcloud.HBuilder/.HBuilder/apps/HBuilder/www/audio/shake.wav': Permission denied
检查了各个权限设置，都没有问题。
也检查了SD卡的容量大小，都没有问题，百思不得其解。
