How to execute forever command remotely without using full path? - node.js

Question

I am trying to execute “forever” command remotely using powershell but I am getting error
'forever' is not recognized as an internal or external command
Here is what I am doing. I have the node js script "MyNodeScript.js" which executes the forever command. The script is on the WebServer "MyWebServer1".
Node.Js and Forever is installed on MyWebServer1 globally.
var exec = require('child_process').exec;
var _ = require('underscore');
var winston = require('winston');
var async = require('async');
var mycommand = 'forever -p ./logs --sourceDir ../wf_manager --workingDir ../wf_manager start -a --uid "ServiceApp" ServiceApp.js'
function start(callback) {
async.waterfall([
function (cb) {
executeCommand(mycommand, false, cb);
}
], function done(err) {
if (err) {
winston.error('failed to start all instances by forever:' + err);
} else {
winston.info('successfully started all instances by forever');
}
callback();
});
}
function executeCommand(command, skip, callback) {
async.waterfall([
function (cb) {
exec(command, cb);
}
], function done(err) {
if (err) {
if (skip) {
// skip the error
callback(null);
} else {
callback(err);
}
} else {
callback(null);
}
});
}
module.exports = {
executeCommand: executeCommand,
start: start
}
start(function(){});
On the same MyWebServer1 under same folder i have a powershell script "MyPowerShellScript.ps1" which call this node script. The powershell script has only one line
node D:\myfolder\maintenance\MyNodeScript.js
I can run this powershell script locally on MyWebServer1 and it works fine. But when i try to execute this powershell script as below from remote machine
invoke-command -computername MyWebServer1 -filepath \\MyWebServer1\MyFolder\maintenance\MyPowerShellScript.ps1
i am getting error
error: failed to start all instances by forever:Error: Command failed:
C:\Windows\system32\cmd.exe /s /c "forever -p ./logs --sourceDir
../wf_manager --workingDir ../wf_manager start -a --uid "ServiceApp"
ServiceApp.js"
+ CategoryInfo : NotSpecified: (error: failed t...ServiceApp.js":String) [], RemoteException
+ FullyQualifiedErrorId : NativeCommandError
+ PSComputerName : MyWebServer1
'forever' is not recognized as an internal or external command, operable program or
batch file.
Note that i can execute the script remotely without any error if i update "MyNodeScript.js" and use full physical path for the forever command
var mycommand = 'C:\\Users\\admin\\AppData\\Roaming\\npm\\forever -p ./logs --sourceDir ../wf_manager --workingDir ../wf_manager start -a --uid "ServiceApp" ServiceApp.js'
However i would like to use just forever command. The path is already added as Environment variable on MyWebServer1

Try calling the ps1-file like this:
Invoke-Command -Scriptblock {powershell.exe -command {d:\blah\MyPowershellscript.ps1 } }
Via -filepath your specify a local scriptfile that should be executed remotely. As your script is present on the target system, you can omit that.
