xcrun无法复制到/ var/folders

我在尝试运行/ usr/bin/xcrun时遇到错误

 /usr/bin/xcrun -sdk iphoneos PackageApplication /Users/xxxx/bamboo-agent-home/xml-data/build-dir/BEAM-IOS0-JOB1/archive.xcarchive/Products/Applications/MyApp.app -o /Users/xxxxx/bamboo-agent-home/xml-data/build-dir/BEAM-IOS0-JOB1/MyApp.ipa --sign "iPhone Distribution: MyComp" --embed /Users/xxxx/bamboo-agent-home/xml-data/build-dir/iOS_Team_Provisioning_Profile_.mobileprovision

和错误是这样的:

error: Unable to copy '/Users/xxxxx/bamboo-agent-home/xml-data/build-dir/iOS_Team_Provisioning_Profile_.mobileprovision' 

to    '/var/folders/1t/pgh7fy550vl8nrvtmqhvn_780000gn/T/cjftmH0k7i/Payload/MyApp.app/embedded.mobileprovision'

任何的想法？这个案子怎么了？
