grunt錯誤——Fatal error: Unable to find Gruntfile，gruntgruntfile

grunt錯誤——Fatal error: Unable to find Gruntfile，gruntgruntfile

E:\website\jquery-plugins>gruntA valid Gruntfile could not be found. Please see the getting started guide formore information on how to configure grunt: http://gruntjs.com/getting-startedFatal error: Unable to find Gruntfile.

錯誤提示Gruntfile.js檔案找不到，但項目中已經有Gruntfile.js檔案，後來發現是用npm安裝grunt模組時，沒有安裝完整（可能是中途中斷了安裝，但grunt模組的目錄已經存在與node_modules目錄下），解決辦法是重新安裝grunt模組:

E:\website\jquery-plugins>npm install grunt

再次執行:

E:\website\jquery-plugins> gruntLoading "uglify.js" tasks...ERROR>> Error: ENOENT, no such file or directory 'E:\website\jquery-plugins\node_modules\grunt-contrib-uglify\node_modules\uglify-js\lib\utils.src'Warning: Task "uglify" not found. Use --force to continue.Aborted due to warnings.

錯誤提示沒有這個檔案或者目錄，猜測grunt的uglify外掛程式也沒有安裝完整，重新安裝：

E:\website\jquery-plugins>npm install grunt-contrib-uglify --save-dev

執行grunt的預設tasks（我這裡的預設tasks只有uglify）

E:\website\jquery-plugins>gruntRunning "uglify:build" (uglify) task>> 1 file created.Done, without errors.
