My npm version is : 7.14.0

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)

Node - Tried to run the file "server.js" through CLI by typing node server.js but it shows message as Cannot find module

Find Visual Studio Code application where I tried to run the file. Things look fine but it says cannot find module. Find my terminal output below along with screenshot in "Node Program"

You have to run npm i and then restart your application and vs code.

Install NPM by typing npm i and then restart your application

Running "ng" causes "Unexpected token ..."

When I run ng with any command, then causes
ng -v

node -v

npm -v

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:
SyntaxError: Invalid flags supplied to RegExp constructor '*username*'

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.
