如何在centos7上安装ruby和compass

Posted 2022-07-30 陈小峰_iefreer

踏得网迁移服务器（CentOS5->CentOS7）时，遇到了一些麻烦，这里记录一下。

Compass是用来编译SCSS语法的，依赖于Ruby，虽然目前该项目可能已经不再活跃，但不能影响历史代码的应用。

yum install centos-release-scl-rh centos-release-scl

next install the right version 

yum --enablerepo=centos-sclo-rh  install rh-ruby26

then enable ruby2.6 in bash

scl enable rh-ruby26 bash

If you would like the change to be permanent (the change still persists after you log out and log back in)

you can edit your $HOME/.bashrc file to include the following line:

source scl_source enable rh-ruby26 

to verify if ruby 2.6 is installed properly or not:  

ruby --version
ruby 2.6.2p47 (2019-03-13 revision 67232)

Ensure you install the header files when you compile gem 

yum install http://mirror.centos.org/centos/7/sclo/x86_64/rh/rh-ruby26/rh-ruby26-ruby-devel-2.6.2-118.el7.x86_64.rpm

或者 yum --enablerepo=centos-sclo-rh-testing install rh-ruby26-ruby-devel

Finally

gem install compass
