Bower. Doesn't work in console.?

Question

bower

Good day to all.
When you type bower help, it says "bower is not an internal or external command, ..." .
bower was installed with npm install -g bower . The content of PATH is:
D:\Program Files\nodejs\node_modules\;C:\Users\GSU\AppData\Roaming\npm;D:\Program Files\nodejs\node_modules\npm\npm\bower\;D:\Program Files \nodejs\node_modules\npm\npm\node_modules\bower\bin\bower\ .
What does he need?
