ERROR: Loading command: install (LoadError)

Ruby

Hi all,

I have encountered a problem when learning Ruby. I am trying to install
several gems on ubtuntu. I install them with the following command:

gem install the_name_of_a_gem

But then I got the error message below:

ERROR: Loading command: install (LoadError)
cannot load such file – zlib
ERROR: While executing gem … (NameError)
uninitialized constant Gem::Commands::InstallCommand

Have I done something wrong here. Any help appreciated.

Looks like you are using RVM. If so, then install zlib1g-dev
and libssl-dev, then reinstall whatever Ruby version you are using.
