'sails' is not recognized as an internal or external command,
operable program or batch file.
So basically I use Windows 10 and I need Sails up and running. I saw on YT people working with that with no problems. I really wanna use Sails.js because it's amazing but I cannot use it.
I don't know what's wrong. I'm doing everything like they say to do. I've installed it globally through npm and of course, I have Node installed and still, I have that error...
What should I do?
It looks like you are missing the path to the sails script in the PATH environment variable. What you can do is find where your sails have been installed:
dir sails.cmd /s
After you find it, open windows menu and type directly 'env' and then select 'Edit the system environment variables'. In the opened window click on the 'Environment variables...' button and add the path to the 'Path' variable.
However, a more preferable way is to uninstall everything (node included) and use the nvm (Node Version Manager) program to get the node itself. You can find it here:
https://github.com/coreybutler/nvm-windows/releases
Then use it to get the node version you want. It is a very useful tool to quickly change between node versions. After that install sails as usual and you should be good to go.

So i just installed VScode on my Windows 10. I keep getting the following error:
"Can't find Node.js binary "node": path does not exist. Make sure Node.js is installed and in your PATH, or set the "runtimeExecutable" in your launch.json"
I've tried reinstalling VS and rebooting, tried installing from different folders (both on C drive and the second time i added it to my programs folder)
I tried installing a node.js extension which fails every time and then prompts me to try it manually...which then leads to a file downloading automatically, but when i add it to my VS folder through my file explorer, nothing happens still.
I tried installed a different node.js debugger
I tried changing my debugger to chrome too but all it does is take me to localhost:8080 and an empty page of course.
When i go through file explorer and look through the path of my .vscode folder, the nightly extension (node.js) is there....
I'm new to VScode and have just been using Scrimba's terminal to do my code but decided to try something more professional
I think you're putting node.js in the same folder/path as .vscode, this isn't correct. What you need to do is set node.js in your PATH which is different. See this answer for more information on how to set PATH/environment variables. Also install it from the official website nodejs.org. After changing your PATH remember to reboot.
I wouldn't recommend downloading "node.js extensions" as those likely are not legitimate, and as you've said yourself they don't work. Only download from the official website.
You have to install nodes from this website https://nodejs.org/
I tried so but I have a 'require is not defined' error. I can't find information about that, can someone enlighten the noob in me please?
It's possible, but you have to be careful. Trying to require() a package means that node will try to locate its files in your file system. A chrome extension only has access to the files you declare in the manifest, not your filesystem.
To get around this, use a module bundler like Webpack, which will generate a single javascript file containing all code for all packages included through require(). You will have to generate a separate module for each component of your chrome extension (e.g. one for the background page, one for content scripts, one for the popup) and declare each generated module in your manifest.
To avoid trying to setup your build system to make using require() possible, I suggest starting with a boilerplate project. You can check out my extension to see how I do it.
An updated answer for 2022
Short answer: yes, you can require/import packages. Rather than going through the tedious work of setting up & configuring a bundler like Webpack on your own (especially if you have no experience with them), there are now build tools you can use to create the boilerplate "scaffolding" for a Chrome extension:
Extension CLI -- this one is well-documented and you can also reference the source code of some Chrome extensions that have used this tool (READ: learn how others have set up their code).
Chrome Extension CLI
Benefits of using them:
New projects are initiated with a default project file structure. Super helpful.
They support modern Javascript (ES6, ES2021), so modules work fine.
They already have bundlers integrated and pre-configured (Webpack in both above cases I think). You therefore don't need to install and configure any on your own.
You can use npm as normal to install any packages/dependencies you need.
Then of course, let the official documentation for Chrome Extensions guide you through the rest.
It's not possible to require node modules directly within a chrome extension. However, it is possible to bundle node applications and packages into the browser for use with your extensions. See here for more: Is it possible to develop Google Chrome extensions using node.js?
Yes, It is possible with esm npm packages.
require is commonjs module loader.
Browser doesn't support commonjs modules system
so that this error showed.
Method 1:
Run npm init -y and add "type" :"module" in your package.json.
create path.js file
add this line in path.js
const fullPath = await import.meta.resolve("npm-pkg-name");
const path = fullPath?.match(/(/node_modules.*)/)[0];
console.log(path);
add this line inside package.json
"path": "node --experimental-import-meta-resolve path.js",
Copy console output text. Replace package name with this copied path.
Method 2:
Install other npm package to find and replace
npm packages' virtual path to real path so that chrome browser will find it.
Install Path-fixxer
Add this line in path.js
import setAllPkgPath from "path-fixxer";
setAllPkgPath();
then run command : npm run path.
Now open browser to test it.

I have tried to install meteor js 1.1 on windows 8.1 with the official installer:
https://github.com/meteor/meteor/wiki/Preview-of-Meteor-on-Windows
But even after restarting my computer, when I type the command meteor in the command prompt I get the error command not found.
Even after a search on my computer to find the installation folder of meteor, I am unable to find the answer. However, in the add/remove program utility, I can see meteor.exe.
As a note, I already successfully installed meteor before, and it used to run smoothly. In the meantime, I have removed and re-installed node, and it seems that since this moment the command meteor does not work anymore. Hence my attempt to re-install it.
Does anyone have any idea about how to troubleshoot my issue ?
I just solved my issue by using the windows command prompt instead of the git bash
It appears that only windows command prompt is supported so far.
You can try to manually add Meteor to your Path.
Go to "Environment variables" (you can find it by doing a simple search in your welcome screen) and add the following entry:
C:\\Users\\**your_user_name**\\AppData\\Local\\.meteor
Do not forget to separate this entry from other entries by a semicolon ;.
I am not that good at computers but am trying to use JSDoc for one of my projects,
The tutorial to get it up and running is here
http://usejsdoc.org/about-jsdoc3.html
I have downloaded the program from github, but now do not understand what I have to do. I have a bunch of files in a folder and dont know how to get it actually running for my project.
Could someone please give me a step by step instruction on how to actually get JSDoc working, how do I set it up, how do I use it etc.
I know this may be mundane to some of you, but hey we all gotta start somewhere right?
Well, are you using windows or GNU/Linux?
First, you have to follow the default tags to markup your source code, identifying your classes, methods, parameters, etc...
After that, you download the file here: https://github.com/jsdoc3/jsdoc
Extract it and then go to folder jsdoc-master.
Inside it, you have a script called jsdoc (with no extension). Only you have to do is execute it pointing the whole path to your .js file you want to create a documentation like this: ./jsdoc your_class.js
Then, in a couple minutes you'll have the output inside the 'out' folder. Open the .html file and bang! You have your documentation working pretty good.
Right here you can find some common tags to use in your code (as comments): http://usejsdoc.org/
This solution is for Unix based system. But, there is another one using nodejs (that you can run with windows, Linux, mac, etc...). First, download the nodejs here: http://nodejs.org/
Then go to this website to take a look at the package jsdoc: https://npmjs.org/
Then, go back to your terminal (in any operating system after installed node) and type: npm install -g jsdoc
The option -g means globally, so you have inside the main folder of your node packages and they are available for whatever project you have and you don't need to install it again and again...
Finally, you can just use this command: jsdoc path/to/your/file.js
And that's it! I hope it helps you.
Once you've extracted the file you downloaded off of github, navigate within the folder and run in a terminal:
./jsdoc
with the options you want.
If you want to display the help menu
./jsdoc --help
If you want to install the program on your system, assuming a mac or linux machine, use root user or sudo:
npm install --save -g [~/Downloads/jsdoc-3.2.2 or your path to the downloaded extracted files]
