Error: uglifyjs not found

Question

I want to minify a folder automatically by a command line. I then installed npm install -g minify-all, then minify-all /opt/myapp/. It gives:

Click to copy

minify-all /opt/myapp/
found file: /opt/myapp/addin_online/css/Common.css
/usr/local/lib/node_modules/minify-all/node_modules/node-minify/lib/node-minify.js:104
          throw new Error(bin + ' not found !');
          ^

Error: uglifyjs not found !

Does anyone know how to fix this? Is minify-all the right package to use?

Edit 1: I tried sudo npm install uglify-js -g

Click to copy

/usr/local/bin/uglifyjs -> /usr/local/lib/node_modules/uglify-js/bin/uglifyjs
/usr/local/lib
└─┬ uglify-js@3.0.11 
  ├─┬ commander@2.9.0 
  │ └── graceful-readlink@1.0.1 
  └── source-map@0.5.6 

And sudo npm install uglify-js -save--dev under /opt/myapp/

Click to copy

async@0.2.10 node_modules/uglify-js/node_modules/async -> node_modules/swig/node_modules/async
flapper-news@0.0.0 /opt/myapp
├─┬ swig@1.4.2
│ └─┬ uglify-js@2.4.24 
│   └── source-map@0.1.34 
└─┬ uglify-js@3.0.11 
  ├─┬ commander@2.9.0 
  │ └── graceful-readlink@1.0.1 
  └── source-map@0.5.6 

However, minify-all /opt/myapp/ still shows:

Click to copy

found file: /opt/myapp/addin_online/css/Common.css
/usr/local/lib/node_modules/minify-all/node_modules/node-minify/lib/node-minify.js:104
          throw new Error(bin + ' not found !');
          ^

I don't have to use uglify-js, I just want to minimise js and css. Is there any other options?

Answer 1

If you really use uglify, you need to go install uglify-js: https://www.npmjs.com/package/uglify-js instead.

npm install uglify-js -save--dev
