What am I missing here?

Answer 1

Add the path to your npm installation to your path. Just add this line at the end of .bash_profile . Run it in bash first, to make sure it works before putting it in .bash_profile

export PATH=$PATH:/Users/username/npm-global/bin

Answer 2

The main problem is that node js does not know the path of the installed modules ..

Type this command to get the path of all the global modules.

npm bin -g

It will display the path (C:\\Users\\gf\\AppData\\Roaming\\npm) and also show (not in PATH env variable)

Copy the path and add it to the path variable of your computer (just like you do while installing other software) for eg : In Windows 7 - Right click on my computer ->select properties -> select advanced system settings -> environment variables

Double click on the Path variable

In the variable value first type a semicolon and paste the path which you copied and that's it every thing should work now..

Answer 3

Just a note, don't just blindly copy and paste the path /Users/username be sure you do the

npm bin -g

as explained by others and get that actual path into export PATH=$PATH:/YourActualPathHERE

Answer 4

In my case (Ubuntu with npm installed from package) live-server module was not installed. It helps:

Answer 5

try to install as root/Administrator

Answer 6

Update to http-server. You can install globally using

npm install --global http-server

You can find the docs at https://www.npmjs.com/package/http-server

Answer 7

If you on windows 10.

Assuming Nodejs is installed, npm is installed, GitBash terminal is installed

1.Install Linux subsystem for windows: Open PowerShell and type:

Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux

3. Open gitBash.exe terminal and type: $ npm bin -g

4. Copy the Path: C:\\Users\\YourMachineName\\AppData\\Roaming\\npm

5.Click the search icon and type Environment...

6.Choose Edit environment variables for your account

7. Go back to Your code Editor, or another terminal and test the work.
8. There is a probability that Powershell will not work. That is why you should select GitBash as your default terminal if you develop a website using VSCode on Windows.

Answer 8

Just try to use live-server in your project as a dev-dependency. Yes, it is not the recommended way. But it is a shortcut and will save your precious time.

Answer 9

My npm live-server works well until it suddenly stopped without any error. I then must change to use live-server of Visual Studio code instead. After read many article i found that my path variable missing C:\Windows\System32\ variable. Check carefully your path environment variable to make sure you have all the addresses needed.
