最新版本 mui 真机调试，每次同步都报错

正在建立手机连接...
正在同步手机端程序文件...
rm failed for /storage/emulated/legacy/Android/data/io.dcloud.HBuilder/.HBuilder/apps/HBuilder/www/, Device or resource busy
mkdir failed for /storage/emulated/legacy/Android/data/io.dcloud.HBuilder/.HBuilder/apps/HBuilder/www/, Device or resource busy
同步失败，失败原因：failed to copy '/Applications/HBuilder.app/Contents/configuration/org.eclipse.osgi/bundles/444/data/run_tmp/./article/subpage.html' to '/storage/emulated/legacy/Android/data/io.dcloud.HBuilder/.HBuilder/apps/HBuilder/www/article/subpage.html': Device or resource busy

只有去手机中删除项目后再同步才行，但是下一次又不行了。必须再次删除。
