Error installing redis: redis requires Ruby Version & gt= 2.3.0.
Error installing redis: redis requires Ruby Version & gt= 2.3.0.
Recently, the following error was reported when installing redis cluster:
the version of ruby in centos7 Yum library supports 2.0.0, but gem needs at least 2.3.0 to install redis, and uses RVM to update ruby
Follow the steps below
1. Install curl
yum -y install curl
2. Install RVM
curl - L get.rvm.io | bash - s stable
this is an installation failure error
this situation mostly occurs in self signed certificates. The error report means that the issuing certificate authority is not authenticated and cannot be identified.
3. Modify hosts
VI/etc/hosts
add the following
199.232.28.133 raw.githubusercontent.com
4. Execute curl command and download RVM
curl - L get.rvm.io | bash - s stable
Load shell configuration
source/usr/local/RVM/scripts/RVM
5. Check the known Ruby versions in RVM library
rvm list known
6. Install the ruby version
rvm install 2.6.3
7. Use Ruby Version
rvm use 2.6.3
8. Set the default version
ruby --version
9. Uninstall the old version
rvm remove 2.0.0
10. Install the interface version of redis and ruby
gem install redis
This is the perfect solution~
