After installing gulp.js via npm, I receive a no command \'gulp\' found error when running the gulp command from the same directory it was installe
That's perfectly normal.
If you want gulp-cli available on the command line, you need to install it globally.
npm install --global gulp-cli
See the install instruction.
Also, node_modules/.bin/ isn't in your $PATH. But it is automatically added by npm when running npm scripts (see this blog post for reference).
So you could add scripts to your package.json file:
{
"name": "your-app",
"version": "0.0.1",
"scripts": {
"gulp": "gulp",
"minify": "gulp minify"
}
}
You could then run npm run gulp or npm run minify to launch gulp tasks.
