我正在尝试为 rails
构建一个 bundlerEnv
。 Nix 不知何故知道 nokogiri
(rails
的依赖项)需要 zlib
、libxml2
和 libxslt
但编译失败。
#Gemfile
gem "rails"
#default.nix
{ pkgs ? import <nixpkgs> {} }:
with pkgs;
bundlerEnv {
name = "smt";
inherit ruby;
gemfile = ./Gemfile;
lockfile = ./Gemfile.lock;
gemset = ./gemset.nix;
}
$ nix-build
...

*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers. Check the mkmf.log file for more details. You may
need configuration options.
不幸的是,运行 find/nix -name mkmf.log
失败。但是使用 Nix 环境手动配置 nokogiri
成功 ( detais )
最佳答案
我曾有过这样的配置:
with import <nixpkgs>{};
let
bundler_ = bundler.override {
ruby = ruby_2_3;
};
bundix_ = bundix.override {
bundler = bundler_;
};
gems = bundlerEnv {
name = "company-bundler";
inherit ruby_2_3;
gemfile = ./Gemfile;
lockfile = ./Gemfile.lock;
gemset = ./gemset.nix;
};
in
stdenv.mkDerivation rec {
name = "company-tools";
version = "0.1.0";
buildInputs = [
# Ruby
ruby_2_3
bundler_
bundix_
rake
gems
# Nokogiri
libiconv
libxml2
libxslt
zlib
];
shellHook = ''
# use a Gem directory within nix
export GEM_HOME=$out/.gems
export PATH=$out/.gems/bin:$PATH
# For nokogiri
export XSLT_LIB=${stdenv.lib.makeLibraryPath [ libxslt ]}
bundle config build.nokogigi --with-xslt-lib=$XSLT_LIB
'';
}
我认为关键位是 XSLT_LIB
var 和 bundle config
位
