Bundler 找不到兼容版本

Question

我的应用中有多个 gem 失败。我的捆绑器无法为所有人找到兼容的版本。我也没有“Gemfile.lock”，也没有在bundle install 上创建。如下：

Bundler could not find compatible versions for gem "actionpack":
  In Gemfile:
    draper was resolved to 2.1.0, which depends on
      actionpack (>= 3.0)

    jquery-datatables-rails (~> 3.3.0) was resolved to 3.3.0, which depends on
      actionpack (>= 3.1)

    rails (= 4.1.6) was resolved to 4.1.6, which depends on
      actionpack (= 4.1.6)

    rails-api was resolved to 0.4.1, which depends on
      actionpack (>= 3.2.11)

    ransack was resolved to 1.8.10, which depends on
      actionpack (< 5.2, >= 3.0)

    redis-rails was resolved to 5.0.2, which depends on
      redis-actionpack (< 6, >= 5.0) was resolved to 5.1.0, which depends on
        actionpack (< 7, >= 4.0)

Bundler could not find compatible versions for gem "activemodel":
  In Gemfile:
    acts_as_api (= 1.0.1) was resolved to 1.0.1, which depends on
      activemodel (>= 3.0.0)

    carrierwave (>= 1.0.0.beta, < 2.0) was resolved to 1.3.2, which depends on
      activemodel (>= 4.0.0)

    paperclip (~> 4.3.2) was resolved to 4.3.7, which depends on
      activemodel (>= 3.2.0)

    rails (= 4.1.6) was resolved to 4.1.6, which depends on
      activemodel (= 4.1.6)

Bundler could not find compatible versions for gem "activerecord":
  In Gemfile:
    activerecord-postgres-hstore was resolved to 0.7.8, which depends on
      activerecord (>= 3.1)

    audited (~> 4.7) was resolved to 4.8.0, which depends on
      activerecord (< 5.3, >= 4.0)

    rails (= 4.1.6) was resolved to 4.1.6, which depends on
      activerecord (= 4.1.6)

我正在使用以下规格再次尝试并获得相同的结果。 捆绑器：1.16.6 导轨：4.1.6 红宝石：2.3.8 ubuntu：18.04

当我执行 gem list 时，我可以看到我的 gem，但它仍然说 bundler 无法为 rails 4.1.6 找到任何东西。

在您的 Gemfile 中添加 source，如下所示：

宝石文件

source 'https://rubygems.org'

删除Gemfile.lock 中的所有内容并运行bundle install
