in the vue project, run the npm run build package to report an error as follows: 
 Error: EPERM: operation not permitted, unlink"Cazzo UserswangyuchiPicturesxufadistence cimg20180508134210.5d873f5.jpg" 
 npm err! Code ELIFECYCLE 
 npm err! Errno 1 
 npm err! Xufast@1.0.0 build:  node build/build.js  
 npm err! Exit status 1 
 npm err! 
 npm err! Failed at the xufast@1.0.0 build script. 
 npm err! This is probably not a problem with npm. There is likely additional logging output above. 
 npm err! A complete log of this run can be found in: 
 npm err! C:UserswangyuchiAppDataRoamingnpm-cache_logs2018-05-15T01_53_53_769Z-debug.log 
 but there is no problem with npm run dev. How should it be solved?
