Error on installing ruby with jemalloc
jemalloc, ruby, rvm
Solution
On [xK]ubuntu 18.10
I did
sudo apt install libjemalloc-dev
rvm install 2.5.2 -C --with-jemalloc
rvm use 2.5.2
ruby -r rbconfig -e "puts RbConfig::CONFIG['LIBS']"
Problem
I am on ubuntu 12.04.5 LTS and tried installing ruby with jemalloc. The jemalloc got installed successfully(https://blog.scalingo.com/2017/05/02/improve-ruby-application-memory-jemalloc.html) but while installing the ruby 2.3.4, it gave this following error. ``` >rvm install 2.3.4 -C --with-jemalloc Warning, new version of rvm available '1.29.1', you are using older version '1.27.0'. You can disable this warning with: echo rvm_autoupdate_flag=0 >> ~/.rvmrc You can enable auto-update with: echo rvm_autoupdate_flag=2 >> ~/.rvmrc ruby-2.3.4 - #removing src/ruby-2.3.4..
