I am trying to execute a file using the terminal included in Visual Studio Code. However, I cannot seem to get it working and end up receiving the following error message:
Example, "node myfile.js" --> module.js:549
throw err;
^
Error: Cannot find module c:\somepath
Is there anyone who knows what the problem might be?
Run Visual studio as Admin and also the Node package location should be accessible for your user
I had your problem before
you should run cmd as administrator.
then type : powershell set-Executionpolicy Remotesigned
and
enter.
now you can run node in vscode .

I am very new to coding, and have just installed VS Code, and installed Node.js as well as Git Bash. I was working on a project, but couldn't console.log anything as I always received the following error when using Git Bash:
bash: syntax error near unexpected token `validateCred' (One of the
variables I used)
I created a new JS file, and ran the following code:
const hello = 'hello world';
I still received the same bash error. I have tried replacing my code with code that I know works and still receive the same errors.I have also tried using Powershell as my terminal, but receive the following errors every time:
batch : The term 'batch' is not recognized as the name of a cmdlet,
function, script file, or operable program. Check the spelling of the
name, or if a path was included, verify that the path is correct and
try again.
I am at a loss, and I'm sure it's something really simple, but I can't seem to figure it out!
A Bash shell expects you to enter Bash code and not JavaScript code.
If you want to run JavaScript code then you need to run it in Node.js and not in Bash.
Generally, the command node will launch Node.js in a Bash shell. (Assuming it is installed on the $PATH).
I want to use the linter package in the Atom Editor. I have installed the packages "linter" and "linter-jshint". Additionally I installed jshint via npm (globally) and downloaded the jshint-repo from GitHub.
When I just try to run the linter on an open .js file in Atom, it fails with message "Error running JSHint". The same happens if I point the executablePath for linter-jshint in the Atom config to the downloaded repo folder.
When I set the executablePath to the node.js Module ("linter-jshint": executablePath: "C:/Users/Username/AppData/Roaming/npm/node_modules/jshint") it just shows a warning ("JSHint return an invalid response, check your console for more info"). Developer Tools console shows:
[Linter-JSHint] SyntaxError: Unexpected end of JSON input
at JSON.parse ()
at Object. (main.js:157)
at Generator.next ()
at step (C:\Users\Username.atom\packages\linter-jshint\lib\main.js:3)
at process._tickCallback (internal/process/next_tick.js:103)
What am I doing wrong? Do I have to point to another subdir or a specific file?
Username contains space and a german umlaut "รถ".
PS: I can execute jshint from command line and it works.
On Executable Path field, you should actually point to jshint executable file, like this:
H:\node_modules\jshint\bin\jshint
I'm getting an ERROR when trying to run ng build on my angular 4 app.
EPERM: operation not permitted, lstat '<dist directory>'
Has anyone encountered this issue?
TIA
I had the same problem.
As #Mauricio De La Quintana said, the problem is permission.
In my case (Windows environment), I solved the problem by removing the read-only property from the Repos folder and adding write permission to the Everyone user.
This probably a permission issue, just restart your IDE with admin permissions!
In my case I had to restart VsCode as administrator.
While running npm run build - I received error
Open Task Manager -> Select Chrome - > End Task
-> Select VSCode -> End Task
Opened the Project again -> Run npm run Build ---> worked for me
This has happened in my ASP.NET projects. For me this has happened for one of two reasons.
This can be a permission problem so you need to run Command Prompt as Admin.
a. Press win to open the start menu. Type in cmd to search for Command Prompt.
b. Press ctrl + shift + enter to launch Command Prompt as administrator.
This can happen when you build your web project in Visual Studio(or another IDE) and it is currently running.
a. This is a simple fix click the stop debugging and then try 'ng build' again.
Just restarted the VSCode and ran in admin. That solves my problem.
I saw this problem when running IISNODE...
Solution: Ensure that AppPool Identify from IIS has read permissions all the way from root of harddrive to website files.
Full answer is here https://github.com/tjanczuk/iisnode/issues/247
I had this issue while running a build on windows at the same time WSL was running in the directory. The issue was resolved by closing the WSL terminal.
Simply follow these steps
Restart VS Code
run npm run build
I think it is a permission problem, when you do ng build you also delete the previous files. I suggest using
sudo chown -R youruser /pathAngularApp
I had the same problem, and it was related to what #goku_da_master commented, I had the vueJs application running even when my VsCode stopped, I figured it out from the task manager and fixed it like this:
I opened the task manager
I searched if Node.js was running
Right click on the Node.js process
Finish Task
"npm run dev" again
I experienced the same problem. The fix for me was to install the correct node version that the project was requiring (an older one), then closing all terminal windows in VS Code, and relaunching VSC.
To switch node versions, I installed nvm and had to make sure the default alias was pointing towards the exact node version I wanted.
Error : Error: EPERM: operation not permitted, lstat 'C:\Users\Administrator'
We encountered this error after the Windows update.
This Solution worked for me;
Go to C:\Users\Administrator
Rename the file NTUSER.DAT as NTUSER-old.DAT
I downloaded and installed node.js on Windows and I'm following a simple tutorial from nodebeginner.org.
I've created a file called HelloWorld.js which contains just:
console.log("Hello World");
When I type node HelloWorld.js in the node.js console I get:
SyntaxError: Unexpected identifier
I checked my classpath variable and it has the C:\Program Files\nodejs\ on it.
HelloWorld.js is still open in Notepad++ for editing.
What am I doing wrong?
I think you are already in the the console.
Just follow the steps to fix the error:
1) Try doing CTRL + C couple of times. See if you exit the console
2) Then do node HelloWorld.js
I think you will get your output
When in your node console already, you can simply do require("./HelloWorld.js") to get the output. (Given that you are in the directory that contains this file)
When I type node HelloWorld.js in the node.js console I get
You should type JavaScript into the Node.js console.
node is a program name. HelloWorld.js is a command line argument. They are not JavaScript.
You should type those into your shell (e.g. Windows Powershell or bash).
I had the same issue when following an online course, my mistake was that i did not safe the file i was following as .js in the name when saving.
Therefore my Hello.js did not open because it was only Hello
If people are facing below-mentioned error: Uncaught SyntaxError: Unexpected identifier at the time of running, console.log("Hello World"); code with command, node HelloWorld.js, in VS code editor
Problem :
node HelloWorld.js ^^^^^ Uncaught SyntaxError: Unexpected identifier
Solution :
(1) Just install Babel JavaScript extension in VS code editor
(2) After Babel JavaScript extension is installed, save your Program and then run your program with the command, node HelloWorld.js
Definitely will get the expected result.
I'm on linux and I'd the same issue
what I was writing in terminal is :
node
node file.js
all what I had to do is to write node file.js from the start without writing node first .
Although the question is old, I just solved it. So for anyone who still likes an answer: Apparently Node.Js installs two different consoles or executables. There is "Node.js" and there is "Node.js command prompt". Use the latter and it will work
To clarify, I used another tutorial in Dutch. Use the Javascript code in there and then in your web browser type http://localhost:3000. There you will see the Hello World output.
A little late but I figured this out as I'm learning it as well. You are not in the correct Node.js command window:
You are probably trying to run Node.js, ie. the one with the red arrow. This gives you the "Unexpected identifier" error. You want the Node.js command prompt, or the one shown with a green arrow.

On windows hit CTRL + D to exit REPL and then run HelloWorld.js again
This is something I only found out about today is that JavaScript can be run through a windows command line.
So I found out that to run a javascript file in windows cmd.exe you use cscript.
My hworld.js file only has one line
print('hello world');
I try to run this through the command line with
cscript /Prog/hworld.js
It didn't run with the error
Microsoft JScript runtime error: Object Expected
Are there steps i need to follow before simply cscript running a one line javascript file.
I was under the impression that JavaScript will just run out the box.
PS. Java is the development environment set up for the computer I am trying this on, installed and functional
The right command to print text in the console is
WScript.echo("your text");
The rest works pretty much like javascript.
