I am new to windows and recently installed angular with the following steps,
- 1> Downloaded and installed Node, -2> Used npm install -g angular/cli, via command prompt. My question here is - I could see Node.js in the list of installed programs in control panel, I am not seeing angular here. I referred to the PATH environment variable where I could see path for Node.js but no path was specified for angular. Where will I be able to see the programs installed via command prompt ?
I referred google and did thorough exploration of my windows system

I'm new on Angular, and I'm not able to run ng commands on WSL version 2.
I installed Angular CLI running:
npm install -g #angular/cli
After that I created a new npm project folder and a package.json running:
npm init
But every ng command returns:
/mnt/c/Users/xxxxxx/AppData/Roaming/npm/node_modules/node/bin/node: 1: This: not found`
I installed Node.js on Windows with an executable (so under PowerShell, everything works as expected). Am I wrong with this?
I installed Node.js on Windows with an executable before (so on PowerShell works), am I wrong with this?
Not, necessarily "wrong", but it's likely part of the problem. But you are certainly correct to question it and provide it as a critical detail in your post!
While WSL can launch Windows executables, keep in mind that those Windows executables (npm in this case) typically only understand Windows paths, processes, environment variables, etc.
npm on the Windows version of Node is a bit unusual, thought. It provides a Bash shell script, which is actually what is being called when you run npm under WSL. That shell script was originally designed for Cygwin and Git Bash, but I see that Node recently added checks in it for WSL as well. Before that, even (the Windows version of) npm itself would have issues under WSL.
But regardless of whether they've fixed npm to work under WSL, then you run into the next level of issues since Angular hasn't modified ng to detect when it is running under WSL.
Without having dug into the source code, ng is going to see that it is running under the Windows version of Node and try to use Windows tools and paths. In my test under WSL (using the Windows version of Node/npm), what seems to happen is that ng new project tries to start CMD.exe. Since it is running under the Windows version of Node, it naturally assumes that CMD.exe is available.
And it is, but starting CMD.exe from inside WSL will attempt to start in a UNC path (\\wsl$\<distroname>\path\to\current\project\dir or \\wsl.localhost\...). CMD doesn't support UNC paths, so it defaults to the Windows directory itself, and I get:
EPERM: operation not permitted, mkdir 'C:\Windows\project'
While you are getting a different error, to be sure, it's almost certainly related to this root issue.
To make a long story longer, see my advice in the question, How to organize programming languages and libraries in WSL and Windows 10.
To summarize it, when using development tools, either:
Use the Windows version of the toolchain (editor, commandline, SDK, tools, etc.)
Or use all-Linux versions of the toolchain.
Also, though, be careful with Node specifically. You can install:
The Windows version of Node for when you are using Windows tools
The Linux version of Node for when you are using WSL tools
But when you are running in WSL/Linux, make sure that the Linux version of npm and node appear first in the path, before the Windows version. This is, again, because of the fact that the Windows version provides that shell script. If the Windows version comes before the Linux version in your Linux PATH, then you will continue to have issues since the Windows npm will get called under WSL (as it is now).
I am a complete newbie to all this.
I tried to install node.js 4 times and then again uninstalled it every time trying different things, thinking one of them would work.
The link to the question is-Cannot find runtime 'node' on PATH - Visual Studio Code and Node.js
After I typed $node --version in powershell terminal in VSCode (after installing node.js in C drive, defaulting to all recommended options in the setup) I get an error. I have uploaded the image of the error.
the error
Please tell me how to get node.js working with VSCode.
To get the version of Node, just type node --version in the terminal without the "$".
I use Visual Studio Code to develop a TypeScript Node application on Windows 10, with WSL enabled.
Thanks to other threads, I'm almost able to run a VSCode task with Bash on Ubuntu on Windows.
But now I try to do the same with a launch configuration. How can I make a launch configuration to use the node executable installed in WSL instead of the one installed on Windows?
If I run this command directly in the integrated terminal, with Bash, it works :
node src/start.js
But when I press "[F5]" and start a launch configuration that runs this same file, I get an error : "Error: %1 is not a valid Win32 application". This is because the oracledb library is used and has been compiled in Bash, not in Windows.
How can I make a launch configuration use Bash to run Node?
UPDATE : I opened an issue about that on VSCode's GitHub page.
Not if sure you still need help.
open bash outside of the vs code.
then run the following command, to install node.
sudo apt install nodejs-legacy
and you should be able to run node with bash in vs code.
I'm trying to figure out how to do my web development on Windows using the relatively new Windows Subsystem for Linux (Bash on Ubuntu on Windows) in conjunction with Visual Studio Code. I've configured the IDE to use the Bash in its integrated terminal, and I've set the project up such that the files are accessible in both the Linux and Windows file system.
The last thing I want to get set up is to get the IDE set up with NodeJS, but not NodeJS for Windows. I want it to use an installation of NodeJS in the Linux Subsystem. Does anyone know if it's possible to point VS Code to the Node installation in the Linux Subsystem?
This was a stumbling block for me too, until I found out that the real problem is that there's a pathing issue with WSL that creates a conflict if you already have NPM installed for Windows. Hopefully you've already figured this out yourself, but for anyone else who hits this, I'm copying in an excerpt from my longer guide on Visual C + WSL that's specific to this problem alone.
Given what you've said, I'll assume you already have node and NPM already installed in WSL's Ubuntu.
Using your favorite CLI editor (such as nano, vim, emacs, cat and sed… etc), open your ~/.profile
nano ~/.profile
Note: do NOT attempt to edit Linux files using Windows tools. (Thanks to #david-c-rankin's comment for the official link with the bold red text explaining this) If you don't want to use a CLI editor for this in the terminal, see the bottom of the answer this is excerpted from for a link on how to get a GUI one running.
Currently, the default bash PATH variable in WSL is
PATH="$HOME/bin:$HOME/.local/bin:$PATH"
Which is injecting the windows path after the first two binary directories. Unfortunately, this doesn't result in /usr/bin being used before the windows installed npm, so add that before the final $PATH:
PATH="$HOME/bin:$HOME/.local/bin:/usr/bin:$PATH"
Save out, and then either reload the terminal or just source the path file
source ~/.profile
VSCode (v1.18) now has better WSL support for Node:
I use nvm to install Node on Ubuntu, although it should work fine if you install it normally.
e.g.
nvm install 9.2.0
nvm alias default 9.2.0
From the VSCode docs
If you want to run Node.js in the Linux subsystem on Windows (WSL), you can use the approach from above as well. However to make this even simpler, we've introduced a useWSL flag to automatically configure everything so that Node.js runs in the Linux subsystem and source is mapped to files in your workspace.
Here is the simplest debug configuration for debugging hello.js in WSL:
{
"type": "node",
"request": "launch",
"name": "Launch in WSL",
"useWSL": true,
"program": "${workspaceFolder}/hello.js"
}
I opened bash outside of the vs code and run the following command, to install node.
sudo apt install nodejs-legacy
and I'm able to run node with bash in vs code.
Installed node.js
Installed phonegap: npm install -g phonegap
Created the example app: phonegap create hello com.example.hello HelloWorld
Used the run command to test in Android: phonegap run android
What happened next is it didn't detect the Android SDK, so it asked me for build.phonegap.com account. I went ahead and created an account and entered user/pw and like magic, it created the app in the cloud. I pointed my qr code scanner to the screen and it installed on my Android phone. Cool, but...
I wanted to develop locally using the Android emulator. So I followed the instructions (http://docs.phonegap.com/en/3.0.0/guide_platforms_android_index.md.html#Android%20Platform%20Guide) to install Android SDK, change PATH variables, etc.
When I went back to command line and cd to my phonegap root folder, suddenly "'phonegap' is not recognized as an internal or external command...'. I tried to reinstall phonegap with npm and it looks like it installs just fine again, but even when restarting cmd.exe, phonegap commands do not work.
Any ideas? Changing environment variables shouldn't affect phonegap already installed, right? The only other thing I can think is I had to install Ant and made an ANT_HOME system variable..
Apologies for the noob question. I'm sure I'm just messed up something simple here..
Figured this out. I accidentally DELETED the environment variables for node.js when I was trying to APPEND additional environment variables manually for android sdk & Ant. Since phonegap was installed as a node package, it wasn't recognized.
Better reinstall using the Msysgit and give the correct path. In my case envi variable path is as follows,
C:\Program Files\nodejs\; ->NodeJS path
F:\windows_adt\sdk\platform-tools; ->SDK Platform Tools
F:\windows_adt\sdk\tools; ->SDK Tools
C:\msysgit\bin; ->Bin Folder
C:\msysgit\git; ->git
C:\msysgit\libexec\git-core; ->git-core, if you want.
To reduce further errors use the recommended msysgit shell.
