Why won't npm module run on Windows?

Question

npm

In general, I installed gulp on Win7.
I did it like here , except -g I run the gulp
command , but the console says "gulp is not an internal or external command .. blablabla" What could be the problem?

Answer 1

Just gulp needs to be installed with the -g parameter, which makes its installation global for all node projects and there will be no need to specifically add it to the environments.
That is, the command will look like this:
npm install -g gulp

Answer 2

Add path in environment variables to gulp
