Introduction
When you type a command in command prompt, if it's a program, the reason it's available for use is because it's accessible from the PATH.
PATH is an environment variable. There is a PATH variable in your user variables, and a second one in your system variables.
PATH denotes a set of locations on your computer with programs and components that should be available globally.
Solution 1 - Edit your PATH
Firstly locate ng.exe on your computer. You may find it in your program files. If you don't know where to look for it, simply open 'Computer' and do full system search for it.
Once you've located ng.exe you will have to add the location to your user or system PATH variable. Environment variables can be edited in the advanced tab of 'System Properties' after clicking the 'Environment Variables' button.
Add a semicolon and the location of ng.exe to the end of the PATH variable.
You may use a tutorial for editing the PATH found on the internet. Here is an example of a tutorial.
Disclaimer: Editing your PATH incorrectly can cause system issues. A better solution would be to contact the maintainer of the program you're trying to install and have them fix the installer.
Solution 2 - Explicitly Run ng.exe
Firstly locate ng.exe on your computer. You may find it in your program files. If you don't know where to look for it, simply open 'Computer' and do full system search for it.
Once you've located it, instead of using ng serve in your command prompt, copy the file location and use the full file location in replacement of "ng".
Example:
ng serve
becomes
C:\path\to\installation\folder\ng.exe serve
I think this is a linking problem, you may not have installed it globally by including this -g after in the command during installing it Anyways Try this to link it:
npm link @angular/cli
