-bash: gulp: command not found in Mac - macos

Question

I try install gulp in mac like this :
Is-iMac:~ itop$ npm root
/Users/itop/node_modules
Is-iMac:~ itop$ npm config set prefix /usr/local
Is-iMac:~ itop$ npm root -g
/usr/local/lib/node_modules
Is-iMac:~ itop$ sudo npm install -g gulp
After Install I see this error In terminal:

Now when i type gulp for start/run in terminal i see this error:
-bash: gulp: command not found
EDIT:
I try with this comment By archie-voyageur:
npm install --global gulp-cli
And See this error:

How do fix this?

Answer 1

Just came across this issue myself and managed to solve it with:
$ npm uninstall --global gulp gulp-cli
$ rm /usr/local/share/man/man1/gulp.1
$ npm install --global gulp-cli

Answer 2

go to
cd /usr/local/bin
ls -las
if gulp is present delete that directory. (sudo rm -rf gulp) reinstall
gulp-cli
===================================================================
if it is not working uninstall node, npm completely and try again

Answer 3

I think you have gulp installed in your system, or at least you have some files related to gulp. Just do npm uninstall --global gulp gulp-cli and then try to install it again with npm install --global gulp-cli. If this doesn't work, I don't know what is happening on your system.

Answer 4

After pulling my hair out trying all of these, I ended up being able to install stupid gulp by doing
npm uninstall --global gulp gulp-cli
yarn global add gulp

Answer 5

For me it worked only when I installed gulp using npm instead of yarn. Very weird..
