Question

After running:

ionic setup sass

And installing all dependencies, when I try to start gulp , I have this error instead:

/Users/user/Sites/ionic/project/node_modules/gulp-sass/node_modules/node-sass/lib/index.js:22
    throw new Error('`libsass` bindings not found. Try reinstalling `node-sass`?');
    ^

Error: `libsass` bindings not found. Try reinstalling `node-sass`?

I'm trying to reinstall node-sass, but no success so far. Any idea on how to fix this issue?

Thanks!

Answer 1

This workaround has fixed all.

Starting with this setup:

Cordova CLI: 5.3.3 Gulp version: CLI version 3.9.0 Gulp local: Local version 3.9.0 Ionic Version: 1.1.0 Ionic CLI Version: 1.6.5 Ionic App Lib Version: 0.3.9 ios-deploy version: Not installed ios-sim version: 5.0.1 OS: Mac OS X Yosemite Node Version: v4.1.1 Xcode version: Xcode 6.4 Build version 6E35b

I've found a way to avoid to use 'sudo' command. We need before to fix npm permissions following this: https://docs.npmjs.com/getting-started/fixing-npm-permissions and fixing permissions for Node here: http://mawaha.com/permission-fix-node-js/ After this we can check and reinstall software without 'sudo' for npm, n or ionic.

I followed this step:

npm install -g n
rm -R node_modules/ 
npm install node-sass@3.3.3 
npm -g install node-gyp@3
npm uninstall gulp-sass
npm install gulp-sass@2 
npm rebuild node-sass 
ionic setup sass 

Why node-sass@3.3.3? Because it works with latest ionic version: https://github.com/driftyco/ionic/pull/4449

Answer 2

Are you on Node 4? That's a somewhat common issue with the new C bindings. Here's a solution that worked for a lot:

 $ npm uninstall gulp-sass node-sass
 $ npm install node-sass@1.0.3
 $ npm install gulp-sass

Answer 3

I've just fixed problems with libsass or node-sass with this command:

$ sudo rm -rf node_modules/ && cat package.json | sed -i.bak 's/"gulp-sass": "^X.X.X"/"gulp-sass": "^2.0.4"/g' package.json && npm install && ionic lib update

Where X is the version of gulp-sass in your package.json

Explanation:

Remove the old files in node_modules. I'm not sure is necessary to use 'sudo' (in my case, yes).

$ sudo rm -rf node_modules/

Search and replace inside package.json updating gulp-sass version to ^2.0.4. It also creates a backup (package.json.bak),

$ cat package.json | sed -i.bak 's/"gulp-sass": "^X.X.X"/"gulp-sass": "^2.0.4"/g' package.json

---

Reinstall dependencies

$ npm install

---

Update the ionic lib in the project

ionic lib update
