After installation of Gulp: “no command 'gulp&

问题:

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 installed into.

When looking under the node_modules/.bin/ directory, I can see the gulp executable there.

Is there something wrong with my npm installation?

回答1:

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.

I actually have the same issue.

This link is probably my best guess:

nodejs vs node on ubuntu 12.04

I did that to resolve my problem:

sudo apt-get --purge remove node 
sudo apt-get --purge remove nodejs 
sudo apt-get install nodejs
sudo ln -s /usr/bin/nodejs /usr/bin/node

I solved the issue without reinstalling node using the commands below:

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

I solved the issue removing gulp and installing gulp-cli again:

rm /usr/local/bin/gulp
npm install -g gulp-cli

Installing on a Mac - Sierra - After numerous failed attempts to install and run gulp globally via the command line using several different instructions I found I added this to my path and it worked:

export PATH=/usr/local/Cellar/node/7.6.0/libexec/npm/bin/:$PATH

I got that path from the text output when installing gulp.

I had to place sudo before npm install gulp-cli -g.

Running as administrator did not work for me. Maybe it might for some of you.
