Install SCSS-Lint with RubyGems, add a .scss-lint.yml file to control its rules, then run scss-lint against your SCSS files. It remains a workable option for existing Ruby Sass projects, but its repository warns that its Ruby Sass dependency limits future compatibility; for a new project, evaluate Stylelint.
What SCSS-Lint does
SCSS-Lint is a command-line linter for files written in SCSS syntax. It checks code against configurable style rules and reports issues with the file, location, severity, linter name, and explanation. It can scan directories and file patterns or read code from standard input. The project also documents hooks, build-tool tasks, and editor integrations. See the SCSS-Lint repository.
Install SCSS-Lint
The documented prerequisites are Ruby 2.4 or newer, Sass 3.5.5 or newer, and SCSS-formatted files. These requirements refer to the tool’s documented Ruby Sass environment, not indented Sass syntax.
Install globally
gem install scss_lintInstall for a project
Add the gem to your project’s Gemfile, then install the bundle:

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
gem 'scss_lint', require: falsebundle installKeep require: false: SCSS-Lint monkey-patches Sass while traversing its parse tree, so loading it broadly can interfere with other Sass users in the same process.
Run a first scan
Scan a directory
SCSS-Lint searches the directory recursively:
scss-lint app/assets/stylesheets/Scan selected files
Use a glob to limit the scan to matching files:
scss-lint app/assets/stylesheets/**/*.css.scssLint standard input
When piping a file into the command, provide the path SCSS-Lint should associate with the input:
cat some-file.scss | scss-lint --stdin-file-path=path/to/treat/stdin/as/having.scssThe supplied path matters because configuration and exclusions can depend on where a file is located.

Configure rules with .scss-lint.yml
By default, SCSS-Lint looks for configuration in this order: a path supplied with --config, .scss-lint.yml in the current working directory, then .scss-lint.yml in the user’s home directory. It loads the first matching file; it does not merge these locations. Configuration extends the tool’s defaults.
For example, this configuration scopes linting to an application’s stylesheets, excludes plugins, disables a rule, and sets indentation to two spaces with warning severity:
scss_files: 'app/assets/stylesheets/**/*.css.scss'
exclude: 'app/assets/stylesheets/plugins/**'
linters:
BorderZero:
enabled: false
Indentation:
severity: warning
width: 2Each linter can be enabled or disabled, and many have rule-specific settings. Severity can be configured globally or for an individual linter. To generate a configuration that disables currently failing linters, use the Config formatter, for example scss-lint --format=Config with the files you want to check. This can help teams adopt rules incrementally.

Make a narrow inline exception
Use inline comments when a specific file, block, or line needs an exception. For example:
// scss-lint:disable BorderZero
// scss-lint:enable BorderZeroKeep exceptions as small as possible and explain unusual ones in code review.
Use SCSS-Lint in scripts and CI
The default formatter is suited to local feedback. The project also documents JSON, TAP, Files, CleanFiles, and Config formatters. JSON can feed machine processing; Config can help build an initial baseline.

SCSS-Lint’s exit codes let automation distinguish outcomes:
| Exit code | Meaning |
|---|---|
| 0 | No lints |
| 1 | Warnings only |
| 2 | One or more errors |
| 64 | Invalid command usage |
| 66 | Missing files |
| 69 | Required library missing |
| 70 | Unexpected error |
| 78 | Invalid YAML or configuration |
| 80 | A glob matched no files |
A gradual rollout can start by treating warnings as a baseline while the team tunes configuration, then make errors the failure threshold once the rules are established. That is a workflow choice based on the documented severities and exit codes, not a turnkey CI policy supplied by SCSS-Lint.

SCSS-Lint uses opinionated default rules for consistency and can load custom linters from repository directories or Ruby gems. Its repository documentation describes the available formatters and integrations.
Should a new project use SCSS-Lint or Stylelint?
The practical decision is usually between preserving compatibility in an existing Ruby Sass codebase and choosing a tool with a more current setup for a new project. The SCSS-Lint repository says the Sass core team is building Sass in Dart rather than Ruby and warns that SCSS-Lint’s dependency on Ruby Sass will eventually mean losing support for the latest Sass features and bug fixes. The repository lists version 0.60.0, released January 27, 2023, as its latest release.
Stylelint’s current getting-started guide recommends an npm setup with stylelint and stylelint-config-standard-scss, a stylelint.config.mjs configuration file, and a command like stylelint "**/*.scss". The SCSS configuration provides custom SCSS syntax and SCSS-specific rules. Stylelint’s overview says it parses SCSS, Sass, Less, and SugarSS and includes more than 100 built-in rules for modern CSS syntax. See the Stylelint getting-started guide and Stylelint project overview.
| Consideration | SCSS-Lint | Stylelint |
|---|---|---|
| Runtime and package manager | Ruby gem | Node.js packages installed with npm in the current getting-started guide |
| Compatibility direction | Depends on Ruby Sass; its repository warns this will limit support for newer Sass features and bug fixes | Current setup uses the SCSS config package and supports modern CSS tooling |
| Configuration | .scss-lint.yml, with configurable linters, severity, and rule options |
stylelint.config.mjs in the current getting-started guide, using stylelint-config-standard-scss |
| CI behavior | Documented exit codes distinguish warnings, errors, and command or configuration failures | not stated in the cited Stylelint getting-started guide |
| Editor integrations | Project documents integrations for several editors and build workflows | not stated in the cited Stylelint getting-started guide |
| Migration effort | Existing rules and exceptions live in .scss-lint.yml |
Moving requires translating configuration and checking rule differences; direct compatibility is not established by the cited setup guides |
For a maintained legacy repository already built around Ruby Sass and .scss-lint.yml, continuity may outweigh switching costs. For a new repository, the Ruby Sass maintenance warning makes Stylelint the stronger candidate to evaluate. A migration is not just a package swap: teams should map their existing rules and inline exceptions to the new configuration and verify behavior against their own files.
