How can I tell which version of Sass is running with node-sass?

[markweston]

Hi,

This might sound like an odd question but I'm using gulp-sass, a wrapper for node-sass which in turn uses libsass.

I'm confused as to how I know which version of Sass I'm running. Does it simply correspond to the version of node-sass? I found this more self explanatory when using Ruby gems for sass.

Thanks.

Hi,

node-sass is a wrapper around libsass which is an alternate / substitute implementation of Sass language compiler written in C/C++, as opposed to the primary implementation in Ruby language.

Going by sass/libsass#629, we can say LibSass' latest version (v3.2.4) fully conforms with Sass language v3.3 and majority of v3.4 features. In other words, the lines are blur from that perspective. Besides, (IMO) the language version is an implementation detail. However, from node-sass' consumer perspective, the more imperative and distinguishing detail is the LibSass version itself, which node sass emits as follow.

From CLI:

node-sass -v
# or, depending on cwd and env PATH status, you may need:
#
# node_modules/.bin/node-sass -v

# OR even

node -e "console.log(require('node-sass').info)"

# OR -p (processes && evaluates)

node -p "console.log(require('node-sass').info)"

From code usage:

var sass = require('node-sass');
console.log(sass.info);

With latest node-sass, the output is:

node-sass       3.1.1   (Wrapper)       [JavaScript]
libsass         3.2.4   (Sass Compiler) [C/C++]

Let us know if and how we can further improve this experience.

Another way to check the version of an indirect-dependency (node-sass) used in your direct dependency (gulp-sass) is to follow the trail of downloaded dependency files until you get to node-sass folder and check its package.json to see what version of libsass it depends on.

On CLI within your project directory where your node_modules may be (if you're using npm for dependencies):

cat node_modules/gulp-sass/node_modules/node-sass/package.json | grep libsass

My current project outputs:

"libsass": "3.1.0-beta",
  "description": "Wrapper around libsass",
    "libsass",

In case your node-sass (or any other module) is in node_modules dir, instead of this line:
# node_modules/.bin/node-sass -v
you could simply use npx
npx node-sass -v

npm node-sass -v works well

npm node-sass -v works well

It only shows the npm version not the node-sass version i checked

I found this command:

node -e 'console.log(require("node-sass").info)'
