'concurrent' is not recognized as an internal or external command

[mounikagudee]

I'm getting an issue while "npm start" saying: 'concurrent' is not recognized as an internal or external command, operable program or batch file.

Below is the error log: 0 info it worked if it ends with ok 1 verbose cli [ 'C:\Program Files (x86)\nodejs\node.exe', 1 verbose cli 'C:\Users\GD1\AppData\Roaming\npm\node_modules\npm\bin\npm-cli.js', 1 verbose cli 'start' ] 2 info using npm@4.2.0 3 info using node@v6.10.0 4 verbose run-script [ 'prestart', 'start', 'poststart' ] 5 info lifecycle angular2-boilerplate@1.0.0~prestart: angular2-boilerplate@1.0.0 6 silly lifecycle angular2-boilerplate@1.0.0~prestart: no script for prestart, continuing 7 info lifecycle angular2-boilerplate@1.0.0~start: angular2-boilerplate@1.0.0 8 verbose lifecycle angular2-boilerplate@1.0.0~start: unsafe-perm in lifecycle true 9 verbose lifecycle angular2-boilerplate@1.0.0~start: PATH: C:\Users\GD1\AppData\Roaming\npm\node_modules\npm\bin\node-gyp-bin;C:\Users\GD1\Desktop\angular-2-beta-boilerplate-master\node_modules.bin;C:\ProgramData\Oracle\Java\javapath;C:\Program Files\Java\jdk1.7.0_51\bin;C:\Program Files\Java\jre7;C:\Program Files\Intel\WiFi\bin\;C:\Program Files\Common Files\Intel\WirelessCommon;C:\WINDOWS\system32;C:\Program Files\SourceGear\Common\DiffMerge\;C:\Program Files\TortoiseSVN\bin;C:\Program Files\Microsoft SQL Server\110\Tools\Binn\;C:\Program Files (x86)\Microsoft SQL Server\110\Tools\Binn\ManagementStudio\;C:\Program Files (x86)\Microsoft SQL Server\110\Tools\Binn\;C:\Program Files (x86)\Microsoft SQL Server\110\DTS\Binn\;C:\Program Files\Microsoft SQL Server\110\DTS\Binn\;C:\Program Files\Microsoft SQL Server\120\Tools\Binn\;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\Skype\Phone\;C:\Program Files\Git\cmd;C:\wamp64\bin\php\php5.6.25;C:\ProgramData\ComposerSetup\bin;C:\Program Files (x86)\nodejs\;C:\Program Files (x86)\Git\bin;C:\Program Files (x86)\Google\google_appengine;C:\Users\GD1\AppData\Local\Google\Cloud SDK\google-cloud-sdk\bin;C:\Users\GD1\AppData\Local\Microsoft\WindowsApps;C:\Users\GD1\AppData\Roaming\Composer\vendor\bin;E:\Program Files\Microsoft VS Code\bin;C:\Users\GD1\AppData\Roaming\npm 10 verbose lifecycle angular2-boilerplate@1.0.0~start: CWD: C:\Users\GD1\Desktop\angular-2-beta-boilerplate-master 11 silly lifecycle angular2-boilerplate@1.0.0~start: Args: [ '/d /s /c', 'concurrent "npm run gulp" "npm run lite" ' ] 12 silly lifecycle angular2-boilerplate@1.0.0~start: Returned: code: 1 signal: null 13 info lifecycle angular2-boilerplate@1.0.0~start: Failed to exec start script 14 verbose stack Error: angular2-boilerplate@1.0.0 start: concurrent "npm run gulp" "npm run lite" 14 verbose stack Exit status 1 14 verbose stack at EventEmitter.
