It appears that the path to your node.exe can't be found in the system/environment PATH variable. You need to ensure that the path to wherever you installed Node.js is added to the PATH variable. For instance, if Node is installed at c:\program files\nodejs, then that value needs to be added to the system/environment PATH variable.

https://stackoverflow.com/questions/27864040/fixing-npm-path-in-windows-8-and-10

If you're not able to edit/modify the PATH variable on the Sitecore server, you can instruct the JSS Node engine to look for node.exe at a specific location. By default, the JSS Node engine will use your PATH variable. That setting is declared in this file on a Sitecore instance (with JSS installed): App_Config/Sitecore/JavaScriptServices/Sitecore.JavaScriptServices.ViewEngine.Node.config

You'll see the /configuration/sitecore/javaScriptServices/renderEngines/renderEngine/instance/NodePath value is node by default. You can directly modify this setting to an absolute file path on the server. Or better, patch the config file:

<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/">
  <sitecore>
    <javaScriptServices>
      <renderEngines>
        <renderEngine name="nodejs">
          <instance id="defaults">
            <NodePath>c:\path\to\node</NodePath>
          </instance>
        </renderEngine>
      </renderEngines>
    </javaScriptServices>
  </sitecore>
</configuration>

You should only modify this config setting if you're unable to change the PATH variable or if you have a very specific reason to do so.

    Hello @Adam Weber, thanks for sharing the info. I have un install node.js and did re install again. After that error is fixed.

    Yes, typically the Node installer for Windows will add the appropriate path the PATH environment variable.
