'polymer' is not recognized as an internal or external command

Question

I recently installed nodejs, bower. Then, I installed polymer using this command:

npm install -g polymer

Then, I added the polymer install path:

C:\Users\<user>\AppData\Roaming\npm

Then, I am trying to do polymer init. I am seeing this error:

'polymer' is not recognized as an internal or external command, operable program or batch file.

Can someone please suggest what I can do to get polymer working?

Try installing some other component like `polyserve` or `http-server` and see if you are facing the same problem — a1626, Nov 09 '16 at 14:48
I did `npm install -g gulp`. After that, I was able to do `gulp --version` and I got a result: > [05:01:02] CLI version 3.9.1 — user1700184, Nov 10 '16 at 11:01
was there any error while installing `polymer`? Can you reinstall it and try — a1626, Nov 10 '16 at 13:33

Adding on from akc42's answer:

Make sure you have installed the Polymer Cli
- from a command prompt type: npm install -g polymer-cli
Make sure the npm global install folder is part of the path
- edit "system environment variables"
- add reference to where npm is installed to the PATH: C:\Users\<user>\AppData\Roaming\npm
Open new command window
Type: polymer --version
If polymer can be found, it should display the version of polymer installed

Thanks @Stuy1974, and if, like me and using an app like VS Code to use polymer-cli and after updating the path you still don't see polymer --version, try restarting the app. – Cliff Coulter Dec 05 '18 at 14:26
"add reference to where npm is installed to the PATH: C:\Users\\AppData\Roaming\npm" that was my problem. thanks – Salvatore Pannozzo Capodiferro Jul 23 '19 at 11:29

The command line tool is called polymer-cli. Install that

npm install -g polymer-cli
