ruby-on-rails - 如何在 Rails 3 中安装 authlogic？

Question

我发现 config/environment.rb 文件在 Rails 3.0 版中看起来有所不同。
此外，当我添加行“config.gem”authlogic“.To environment.rb 文件

Answer 1

对于 Rails 3，您不再编辑 config/environment.rb .您编辑 Gemfile , 添加

gem 'authlogic'

到它，然后做一个

bundle install

会有 Gemfile.lock ，它会列出您项目中的所有 gem 及其版本。 Bundler 的文档:

Whenever your Gemfile.lock changes, always check it in to version control. It keeps a history of the exact versions of all third-party code that you used to successfully run your application.

When your co-developers (or you on another machine) check out your code, it will come with the exact versions of all the third-party code your application used on the machine that you last developed on (in the Gemfile.lock). When they run bundle install, bundler will find the Gemfile.lock and skip the dependency resolution step. Instead, it will install all of the same gems that you used on the original machine.
