-bash: gulp: command not found in Mac

问题

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:

npm WARN deprecated graceful-fs@3.0.8: graceful-fs version 3 and before will fail on newer node releases. Please update to graceful-fs@^4.0.0 as soon as possible.
npm WARN deprecated lodash@1.0.2: lodash@<3.0.0 is no longer maintained. Upgrade to lodash@^4.0.0.

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?

回答1:

Just came across this issue myself and managed to solve the issue with:

$ npm uninstall --global gulp gulp-cli
$ rm /usr/local/share/man/man1/gulp.1
$ npm install --global gulp-cli

回答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

回答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.

回答4:

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