I installed zlib package and ruby 1.9.3 using rvm, but whenever I try to install
gems it says
cannot load such file -- zlib
The commands I used to install are
$ rvm install 1.9.3
$ rvm pkg install zlib $ rvm reinstall 1.9.3 --with-readline-dir=/home/username/.rvm/usr \ --with-iconv-dir=/home/username/.rvm/usr \ --with-zlib-dir=/home/username/.rvm/usr \ --with-openssl-dir=/home/username/.rvm/usr $ rvm use 1.9.3 $ gem install heroku ERROR: Loading command: install (LoadError) cannot load such file -- zlib ERROR: While executing gem ... (NameError) uninitialized constant Gem::Commands::InstallCommand
All the help on this subject tells me to just do rvm pkg install zlib
, and
then reinstall the ruby with --with-zlib-dir=/home/username/.rvm/usr
, but this
didn't work.
I ended up installing zlib from apt-get and then reinstalling ruby to not use the rvm directory for zlib.
Here's how do:
$ sudo apt-get install zlib1g-dev
$ rvm reinstall 1.9.3
[Edit] As commenter @chrisfinne mentions, on CentOS/RedHat based systems:
$ sudo yum install zlib-devel
$ rvm reinstall 1.9.3
