I have a usable workflow that I want to make better. I'm building a JS library, and the way I am executing smoke tests on code is by using webpack to package the library and write it to a file that is included in an HTML file for viewing the effects of the code.
To do this, I make changes to the file in Eclipse, save it, then I must leave Leave eclipse and go to Terminal to run "npm run buildInbrowser" to execute "webpack --config inbrowser.config.js".
The configuration works perfect with regards to webpack, the configuration, and the npm setup, but when I try to configure eclipse to run those commands, it brings up an error: "env: node: No such file or directory" I've attached screenshots of my launch NPM configuration.
My system is MacOSX Catalina using Nodeclipse, npm v9.3.1 and node 16.18.0.
Again, there is no issue with me running these commands in terminal, but they won't run through node. This makes me think it's something simple that I overlooked.
As nitind pointed out, I had incorrect syntax on the PATH variable for eclipse, which was causing the problem. Also noted is that Eclipse did not populate my path variable by default, so i did have to manually enter it in. See the screen shot for the fix.
Upon running 'stripe listen' command in terminal in VS Code, it throws an issue :-
The term 'stripe' 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.
Can anybody help me in resolving this?
I have already configured Stripe-CLI for my project using command prompt but it is not working in the terminal of vs code.
You can restart your vscode and then try running your command, if it is running in command prompt outside of vscode. VScode terminal uses available system CLIs like command prompt,powershell & others, so whatever is running outside of vscode terminal, should run in vscode terminal as well.
If your command is not running outside of vscode as well, you can check the PATH variable in your system environment variables (search for environment variables in start menu, assuming Windows OS), whether it contains the path to the folder containing stripe executable file or not. You can add the path if it is not present, then restart your terminals/vscode and try running your command.
First of all, I wanted to learn Node.js, I opened my code editor then logged a simple word. but the problem is when I open my terminal I write :
node server.js
but it says :
'node' is not recognized as an internal command
or external, an executable program or a batch file.
I don't know how to fix the problem even in my editor's terminal.
Seems you haven't installed node on your system. Be sure if you have installed node or not.
Just open your terminal and type node
If you don't see a message like this Welcome to Node.js v14.12.0. then check this official download/setup link.
If you're using Ubuntu, then follow this link.
For any other Linux distro, just search Install node on <manjaro>.
Change with your distro name.
I am trying to run a hello world program written in javascript in a separate file named hello.js
Currently running windows version of node.js.
The code runs perfectly in console window but how do I reference the path in windows environment.
C:\abc\zyx\hello.js
in Unix I guess it is showing $ node hello.js
I'm absolutely new to Node.js Please correct me if I am doing something wrong.
I tried
> node C:\abc\zyx\hello.js ----didn't work
> C:\abc\zyx\hello.js --didn't work
UPDATE1:
Added node.exe to the folder where hello.js file is sitting.
Added path point to the folder c:\abc\zyx\ and I get an error that says
ReferenceError: hello is not defined
see contents of hello.js
setTimeout(function() {
console.log('World!');
}, 2000);
console.log('Hello');
UPDATE 2:
So far I have tried all these version and none of them seems to work. May be I am doing something completely wrong.
>node hello.js
>$ node hello.js
>node.exe hello.js
>node /hello.js
>node \hello.js
> \node \hello.js
> /node /hello.js
> C:\abc\xyz\node.exe C:\abc\xyz\hello.js
> C:\abc\xyz\node.exe C:/abc/xyz/hello.js
> hello.js
> /hello.js
> \hello.js
>node hello
Refer to my file structure
.
├── hello.js
├── node.exe
└── paths.txt
RESOLVED:
Instead of running node.exe, try running in command prompt with the following option and it worked.
c:\>node c:\abc\hello.js
Hello
World! (after 2 secs)
Here are the exact steps I just took to run the "Hello World" example found at http://nodejs.org/. This is a quick and dirty example. For a permanent installation you'd want to store the executable in a more reasonable place than the root directory and update your PATH to include its location.
Download the Windows executable here: http://nodejs.org/#download
Copy the file to C:\
Create C:\hello.js
Paste in the following content:
var http = require('http');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello World\n');
}).listen(1337, "127.0.0.1");
console.log('Server running at http://127.0.0.1:1337/');
Save the file
Start -> Run... -> cmd
c:
C:>node hello.js
Server running at http://127.0.0.1:1337/
That's it. This was done on Windows XP.
Install the MSI file:
Go to the installed directory C:\Program Files\nodejs from command prompt n
C:\>cd C:\Program Files\nodejs enter..
node helloworld.js
output:
Hello World
You need to make sure that node is in your PATH. To set up your path, this out.
Make sure that the directory that has node.exe is in your PATH. Then you should be able to
run node path_to_js_file.js.
For a good "Hello World" example, check out: http://howtonode.org/hello-node
another simple way
download nodejs to your system
open a notepad write js command "console.log('Hello World');"
save the file as hello.js preferably same location as nodejs
open command prompt navigate to the location where the nodejs is located
c:\program files\nodejs
and run the command from the location like c:\program files\nodejs>node hello.js
in case the js file in another location give the path of file
c:\program files\nodejs>node path\hello.js
I installed node for windows.
There is a node.js command prompt when I search for node.js in windows 7 start menu
If you run this special command prompt, you can node anything in any location without setting up the path or copy node.exe everywhere.
WinXp:
I have created a .bat file
node c:\path\to\file\my_program.js
That just run my_program.bat from Explorer or in cmd window
Go to cmd and type: node "C:\Path\To\File\Sample.js"
Windows/CMD does not know where the node file is located. You can manually type out:
path=%path%;"c:\Program Files\nodejs"
each time you open a new cmd.exe prompte
OR (in Windows 10),
right click on This PC -> properties.
Click on Advanced system settings -> Environment Variables (bottom right).
Select Path and click Edit.
Click new and enter C:\Program Files\nodejs.
Reboot and you should be able to run node from any directory.
Just change file association of .js file to node.exe and you can run directly from explorer.
Right click on the file -> Select "Open with" -> Select "Choose another program"
Check box "Always use this app to open .js file"
Click "More apps" -> "Look for another app in PC"
Navigate to node.js installation directory.(Default C:\Program Files\nodejs\node.exe"
Click "Open" and you can just see cmd flashing
Now you will be able to run any .js files directly just by double clicking.
Note: Adding below code to the end of js file will be useful as it will keep the console open for a keystroke.
console.log('Press any key to exit');
process.stdin.setRawMode(true);
process.stdin.resume();
process.stdin.on('data', process.exit.bind(process, 0));
The problem was that you opened the Node.js repl while everyone automatically assumed you were in the command prompt. For what it's worth you can run a javascript file from the repl with the .load command. For example:
.load c:/users/username/documents/script.js
The same command can also be used in the command prompt if you first start node inside the command prompt by entering node with no arguments (assuming node is in PATH).
I find it fascinating that 1)everyone assumed you were in the command prompt rather than repl, 2)no one seems to know about .load, and 3)this has 273 upvotes, proving that a lot of other node.js beginners are similarly confused.
Step For Windows
press the ctrl + r.then type cmd and hit enter.
now command prompt will be open.
after the type cd filepath of file. ex(cd C:\Users\user\Desktop\ )
then hit the enter.
please check if npm installed or not using this command node -v.
then if you installed will get node version.
type the command on command prompt like this node filename.js . example(node app.js)
C:\Users\user\Desktop>node app.js
type node js command prompt in start screen. and use it.
OR
set PATH of node in environment variable.
Install node properly, that's it.
Now open terminal to path where your .js file is.
for example- if Javascript file(fileName.js) is at folder C:\Documents\Project1.
Just go to that folder, type node to check node is enable
then type node fileName.js
Simple! Your work is done!!
c:\> node.exe %CD%\hello.js
%CD% captures the current directory under DOS
For all stuck on how to start!
https://github.com/sethvincent/javascripting
Copy here incase link dies:
Open node.js command prompt
Make directory called javascripting by typing "mkdir javascripting"
Change directory into the javascripting folder by typing "cd javascripting"
Create a file named introduction.js by typing "touch introduction.js" OR FOR WINDOWS: "NUL > introduction.js"
Open the file and type some javascript e.g. "Console.log('hello');"
Save the file and check it runs by typing "javascripting verify introduction.js"
All you have to do is right click the .js file on Windows and press "Open with Command Prompt"
OR
Open cmd, copy the path to the folder containing your script, and run the command "cd [paste text here]". Then do "node example.js"
I had such problem for windows. And I decided it so:
startApp.cmd:
#set JAVA_HOME=C:\jdk160_24
#set PATH=%JAVA_HOME%/bin;%PATH%
#cd /D C:\app\
#start /b C:\WINDOWS\system32\cscript.exe
C:\app\start.js
and saved it cmd file in dir C:\scripts
next file is runApp.bat:
C:\scripts\startApp.cmd
I'm trying to figure out node.js and nothing is working. I can run code using node.js via writing it in the terminal, but I want to run an external js file.
Right now, I have my node.js installed here "C:\Program Files\nodejs\node.exe"
I then made a js file and wrote console.log("Hello World"); and saved it in the same location and called it test.js.
I then opened up a command prompt and tried everything to try run it but nothing works.
The PowerPoint my teacher gave to me says to do "node test.js" and it should output Hello World.
When I try it, it says error cannot find test.js, so I wrote the full file path and it says, c:\program is undefined or something. Can someone please tell me what to write in the command prompt so I can output Hello World via the test.js file I've got saved in the same location as node.exe?
I am using windows if that helps.
You need to put test.js your current directory. If you just open CMD, your current directory defaults to your user directory. Instead of putting your js file next to the node.exe, you have to put it in the directory your cmd is in.
Example:
create test.js in C:\Users\yourname\Documents\test.js
then open CMD and cd C:\Users\yourname\Documents\ to set your CMD's current directory to your documents folder.
From there, node test.js will run the test.js file you have in C:\Users\yourname\Documents\
