如何在ubuntu安装sass预处理器

Sass（英文全称：Syntactically Awesome Stylesheets）是一个最初由Hampton Catlin设计并由Natalie Weizenbaum开发的层叠样式表语言，在开发最初版本之后，Weizenbaum和Chris Eppstein继续通过SassScript来继续扩充Sass的功能。SassScript是一个在Sass文件中使用的小型脚本语言
在本教程中，我们使用Ubuntu安装Sass预处理器，如果直接安装node-sass的话，你也可能会遇到下面的错误

error xxx/node_modules/node-sass-middleware/node_modules/node-sass: Command failed.
Exit code: 135
Command: sh
Arguments: -c node scripts/build.js
Directory: xxxx/node_modules/node-sass-middleware/node_modules/node-sass
Output:
Binary found at xxx/node_modules/node-sass-middleware/node_modules/node-sass/vendor/linux-x64-51/binding.node
Testing binary
Bus error (core dumped)

如果你创建express项目使用sass也会有同样的错误

解决方式

➜ sudo apt search sass |grep lib
➜ sudo apt-get install 
➜ sudo apt-get install libsass-dev

RedHat,Fedora,Centos

➜ sudo yum search sass | grep lib
➜ sudo yum install packname

如果上面的方式还没能安装好，你也可以尝试编译安装

sudo apt-get install libssl-dev
sudo apt-get install zlib1g-dev
mkdir ~/rubysass && cd ~/rubysass
wget https://cache.ruby-lang.org/pub/ruby/2.3/ruby-2.3.1.tar.gz
wget https://rubygems.org/rubygems/rubygems-2.6.7.zip
sudo apt-get update && sudo apt-get install -y tar unzip
tar zxvf ruby-2.3.1.tar.gz && unzip rubygems-2.6.7.zip
cd ruby-2.3.1
./configure && make && sudo make install
cd ~/rubysass/rubygems-2.6.7
sudo ruby setup.rb
cd ~ && sudo gem install sass
