执行“npm run build”时出错

Question

我无法解决这个意想不到的问题！

执行npm run build时出现此问题：

npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! *********@1.2.0 build: `gulp`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the *********@1.2.0 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:
