I'm trying to use uglifyjs via command line, and it's not going well.

I've tried many variations of $ [sudo] npm install uglify-js -g, but in all cases, when I try to run uglifyjs as a command $ uglifyjs it says command not found.

In every case, it seems like uglify gets installed. Version 2.4.0 is listed under $ npm list -g as being installed.

I'm running: node v0.10.17 (installed via pkg from node homepage ) npm v1.3.8

I've restarted a couple of times after various installations, but I'm not getting any success.

/usr/local/share/npm/bin/uglifyjs -> /usr/local/share/npm/lib/node_modules/uglify-js/bin/uglifyjs
uglify-js@2.4.0 /usr/local/share/npm/lib/node_modules/uglify-js
├── uglify-to-browserify@1.0.1
├── async@0.2.9
├── source-map@0.1.29 (amdefine@0.0.8)
└── optimist@0.3.7 (wordwrap@0.0.2)
Andrews-MacBook-Pro:node_modules andrewheins$ uglifyjs
-bash: uglifyjs: command not found

Any ideas?

    Seems that /usr/local/share/npm/bin/uglifyjs is where the program was installed and /usr/local/share/npm/bin/ is not in your PATH environment variable. What happens if you issue as a command /usr/local/share/npm/bin/uglifyjs ? I am not familiar with this software or your set-up, this is just reasoning from general principles. – micans Aug 28 '13 at 12:48

My problem was that I installed uglifyjs, and not uglify-js. uglifyjs does not include the binary. Just leaving this here if someone else is stuck the same way.

sudo npm install -g uglify-js


Using @micans comment above, and this answer, I was able to get uglify working by adding export PATH=$PATH:/usr/local/share/npm/bin/ to my .bash_profile. Thanks all!


I had the same problem in my Linux Mint installation. I resolved it just executing the follows commands:

sudo apt-get update
sudo apt-get upgrade
