更新 country_state_select gem

Question

我要更新country_state_selectgem...

这是我的 Gemfile

gem 'country_state_select'
gem 'chosen_rails'
gem 'compass-rails'

在 bundle 之后，我将启动我的 rails 应用程序 rails s

我有错误，看起来像

NoMethodError - undefined method `state_options' for CountryStateSelect:Module:
  app/views/shared/users/_light_box_login.html.erb:101:in `block in _app_views_shared_users__light_box_login_html_erb___390633241__632173138'

  actionview (4.2.7.1) lib/action_view/template.rb:145:in `block in render'

我发现 solution

我的意思是gem 'country_state_select', '3.0.1'

但是当添加这个 gem 和捆绑包时，我有另一个问题..

Fetching gem metadata from https://rubygems.org/...........
Fetching version metadata from https://rubygems.org/...
Fetching dependency metadata from https://rubygems.org/..
Resolving dependencies...
Bundler could not find compatible versions for gem "compass-rails":
  In snapshot (Gemfile.lock):
    compass-rails (= 3.0.2)

  In Gemfile:
    compass-rails

    country_state_select (= 3.0.1) was resolved to 3.0.1, which depends on
      compass-rails (~> 2.0.4)

Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.

任何人都可以帮助我..如何更新 gem 版本..

Answer 1

删除 gemfile.lock 文件并在您的 gemfile 中使用 gem 'country_state_select'，然后在终端中使用 bundle install。

Answer 2

尝试bundle update。这已经在你的问题中了。

或者如果您想更新特定的 gem 使用，

bundle update gem-name

更新 country_state_select gem

update country_state_select gem

ruby

rubygems

ruby-on-rails
