Can't install worked rails for nixos with ruby-1.9 from nixpkgs about nixpkgs HOT 5 CLOSED

Thank you.

Later I'll test your recommendations for server based on NixOS (now it's still work on Gentoo)
But now I found temporary solution to use rvm on notebooks with NixOS for study NixOS, rails and haskell.

It's enough:

pkgs:
git
gcc
bash
curl
openssl
sqlite
patch
readline
zlib
libyaml
#iconv
libxml2
libxslt
libtool
bison
v8
nodejs

curl -L https://get.rvm.io | bash -s stable
source /etc/profile.d/rvm.sh
rvm pkg install zlib
rvm pkg install readline
rvm pkg install openssl
rvm install 1.9.3
// : q
rvm use 1.9.3 --default
rvm use 1.9.3@rails3 --create
rvm use 1.9.3@rails3 --default
gem install rails
gem install sqlite3-ruby -- --with-sqlite3-dir=/nix/store/sqlite // replace to actual path in store
gem install libv8

cd to_your_app
bundle install

from nixpkgs.

We have a few gems (including rails) packaged through nixpkgs. nix-env -i ruby-rails-3.2.6 should work (default ruby is 1.9)

from nixpkgs.

Your receipt "nix-env -i ruby-rails-3.2.6" install successful but don't work due to rails belongs to rubygems instead gem from ruby-1.9 and failed find rack.

Oh, sorry, you'll also need to add /.nix-profile/lib/ruby/gems/1.9 to your GEM_PATH, and you might also need to have RUBYLIB=/.nix-profile/lib and RUBYOPT=rubygems

from nixpkgs.

@perestoronin thank you. It work for me, but also requires which and pkgconfig packages for Nix system and libyaml & ncurses for rvm pkg. And I didn't add openssl, readline and zlib to Nix packages.
UPD: but still not able to install gem nokogiri...

from nixpkgs.
