Question

在我的Ubuntu 12.04.4 LTS上安装sqlite，libsqlite0-dev和libsqlite3-dev（以及ruby1.9.3）之后，我做了：

sudo gem install sqlite-ruby

这是我得到的日志：

Building native extensions.  This could take a while...

Gem files will remain installed in /var/lib/gems/1.9.1/gems/sqlite-ruby-2.2.3 for inspection.
Results logged to /var/lib/gems/1.9.1/gems/sqlite-ruby-2.2.3/ext/gem_make.out

有人可以帮我安装那个lib吗？（我的主要问题是将Trac项目迁移到Redmine following that documentation）

感谢Graeme McLean's comment my question，http://boga.wordpress.com/2008/04/15/ruby-19-porting-notes/，https://www.ruby-forum.com/topic/4405578和http://guides.rubygems.org/make-your-own-gem/，我设法修补了sqlite-ruby gem，构建并安装它：

gem fetch sqlite-ruby
gem unpack sqlite-ruby-2.2.3.gem
cd sqlite-ruby-2.2.3/
sed -i 's/RSTRING(\(.*\))->ptr/RSTRING_PTR(\1)/g' ext/sqlite-api.c
sed -i 's/RSTRING(\(.*\))->len/RSTRING_LEN(\1)/g' ext/sqlite-api.c
gem unpack --spec ../sqlite-ruby-2.2.3.gem
sed -i 's/version: 2.2.3/version: 2.2.3.patched/' sqlite-ruby-2.2.3.gemspec
cat >> sqlite-ruby-2.2.3.gemspec <<EOF

gem build sqlite-ruby-2.2.3.gemspec
sudo gem install sqlite-ruby --local

无法安装gem sqlite-ruby
