Node-Red Pm2 Setup - javascript

I am trying to start my node-red on a raspberry pi 2 using pm2. I am using the startup command:
pm2 start /usr/bin/node-red-pi --node-args="--max-old-space-size=128" -- -v
At first it seems to work:
But unfortunatly then it errors:
Thats the log:
SyntaxError: Unexpected token ILLEGAL

at Module.load (module.js:343:32)

Please make sure you installed the latest PM2 version (>2.x):
$ npm install pm2#latest -g
$ pm2 update
Then start node-red again, it should works as expected:
pm2 start node-red --node-args="--max-old-space-size=128" -- -v

As exlained in above comments:
The issue originated from an old version node that didn't recognize the import feature. which is available only since : v13+ ( see https://stackoverflow.com/questions/39436322/node-js-syntaxerror-unexpected-token-import)

Fixed it, by changing docker image, from 'kadirahq/meteord' to 'abernix/meteord:base' in mup.js file.

I tried reinstalling the node, npm and #angular/cli. No solution has helped.
#Edited, Solution
I deleted ng, ng.cmd from C:\nodejs\ and folders #angular/cli/, angular-cli/ fromC:\nodejs\node_modules, and reinstall #angular/cli, and then
works correctly.

'Invalid flags supplied to RegExp constructor' error when running node server.js for Azure IoT Hub

I am trying to run 'node server.js' to connect my raspberry pi device to Azure via the Azure IoT Hub. When I run the command 'node server.js', I receive the following error. Please note that I replaced my computer's user name with 'username'. The file connection_string.js does not have my computer's username in it, despite the error saying that it does. Please see error below:

Thank you in advance for your help!
Not sure if it is your case or not, but I had similar issue:
SyntaxError: Invalid flags supplied to RegExp constructor 'u'
I fixed it simply by updating Node.js.
Previous version was:
$ node -v
v5.1.1
Then I did:
$ curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
... long output
$ sudo apt-get install -y nodejs
... shorter output
$ node -v
v6.7.0
And no more issues.
