跑步时出错＆＃34; gulp＆＃34;

Question

当我尝试在我的webapp文件夹中运行gulp时发生错误：

"
[14:16:06] Finished 'jshint' after 813 ms
[14:16:06] Starting 'usemin'...
Unhandled rejection Error: ϵͳ�Ҳ���ָ����·����

    at notFoundError (D:\project\datacollector\node_modules\cross-spawn\lib\enoe
nt.js:11:11)
    at verifyENOENT (D:\project\datacollector\node_modules\cross-spawn\lib\enoen
t.js:46:16)
    at ChildProcess.cp.emit (D:\project\datacollector\node_modules\cross-spawn\l
ib\enoent.js:33:19)
    at Process.ChildProcess._handle.onexit (internal/child_process.js:215:12)
"

之后我试图跑：

npm cache clean gulp-usemin

但错误再次出现 谢谢你的帮助！
