One, sass installation under Windows
Installing Ruby under the Windows platform requires a Ruby installation package, which you can download here:
https://www.ruby-lang.org/en/downloads/
After the Ruby installation file is downloaded, you can install Ruby by following the application installation steps.
After the ruby installation is complete, locate the newly installed Ruby in the Start menu and launch the Command Control Panel for Ruby Start command Prompt with Ruby. The next step is to install Sass.
1. Install Sass by command
Open your computer's command terminal and enter the following command:
Gem Install Sass
To remind you, in the use of the MAC classmate, may need to add "sudo" before the above command to install properly:
sudo gem install sass
If the above method is not successfully installed, you can use the following two methods.
2. Install Sass via Compass
In addition to using the Gem command to install Sass, you can install Sass by installing compass because compass is a framework based on Sass development. In other words, you install the Compass, and you install the Sass as well.
Similarly, enter the following command at your command terminal:
sudo gem install sass
After executing the above command, the installation of Compass and Sass is started.
Note: Compass is a mature, Sass-based framework that integrates a number of well-written mixins and Sass functions. But there is no more elaboration on this.
3, Local installation Sass
Since sometimes the direct use of the above command installation will make it impossible for you to implement the installation (Network limited reason), when encountered this situation, then the installation needs special to handle, you can use the following method to achieve the normal installation of Sass:
You can download the Sass installation package (Http://rubygems.org/gems/sass) to the Rubygems (http://rubygems.org/) website and enter it at the command terminal:
Gem Install < Drag the downloaded installation package here >
The direct carriage return can be successfully installed.
Note: On the IOSX system platform, you can drag the downloaded installation package directly after the "gem install", if you are a Windows system, you need to enter the file path of the installation.
Second, sass in the detection, update, uninstall
On the command line, start command Prompt with Ruby, enter the commands:
Sass-v Search and test
GEM Update Sass Update Sass
Gem Uninstall Sass Uninstall Sass
SCSS is a new syntax format for SASS, which can be indented, with curly braces, semicolons, and sass different from the writing format and the file name extension.
Third, the compilation of sass
1, command-line compilation:
Single-file compilation: Sass < input path >/style.scss:< output path >/style.css
Multi-file compilation: Sass sass/:css/
The above command means that all ". Scss" (". Sass") files in the "Sass" folder in the project are compiled into a ". css" file, and these CSS files are placed in the project's "CSS" folder.
Watch function on the command line:
Let's look at a simple example, assuming I have a project locally, I'm going to compile the project "Bootstrap.scss" into a "bootstrap.css" file, and put the compiled file in the "CSS" folder, and I can do it in my command terminal:
Sass--watch Sass/bootstrap.scss:css/bootstrap.css
Once I have any changes to my bootstrap.scss file, as long as I save the modified file again, the command terminal can monitor and recompile the file.
2. GUI Interface Tool compilation
Recommended Koala, Codekit these two visual tools compile, specific can be downloaded online.
3. Automated compilation
Grunt, gulp can be automatically compiled.
