Windows – how to use angular cli on a Windows Server in a Jenkins build batch command

before installing Jenkins I ran this:
npm install -g @angular/cli

but I also have this in devDependencies in the package.json for the project:

"@angular/cli": "1.0.0-beta.32.3",

when running a Jenkins build, I get this message in the log:

'ng' is not recognized as an internal or external command, operable program or batch file.

=======================================

Here is the Windows batch command in Jenkins:

cmd /c call npm install

set Path=%WORKSPACE%\node_modules\@angular\cli\bin;%PATH%

echo %PATH%

ng build -prod

========================================

here is a little more log output from Jenkins:

C:\Program Files (x86)\Jenkins\workspace\UiUnitTests>ng build -prod

'ng' is not recognized as an internal or external command,
operable program or batch file.

C:\Program Files (x86)\Jenkins\workspace\UiUnitTests>exit 9009
Build step 'Execute Windows batch command' marked build as failure

but when I run this just from the command line (not in a Jenkins job), this works fine:

C:\Program Files (x86)\Jenkins\workspace\UiUnitTests>ng build -prod

Your global Angular CLI version (1.0.0-rc.1) is greater than your local

version (1.0.0-beta.32.3). The local Angular CLI version is used.

To disable this warning use "ng set –global warnings.versionMismatch=false".

last but not least, here is the Jenkins log output from echo %PATH%
