Question

下面是我的Gemfile，但是我没有指定mysql2版本，但是由于某种原因，它正在寻找0.4.4。它必须是另一个gem的依赖项。我刚刚被分配了任何想法？

Answer 1

mysql2

它将列出let int = 14; // key3 + key4 + key5 let enum { key1: 0, key2: 1, key3: 2, key4: 4, key5: 8, key6: 16, key7: 32, key8: 64 // ..... } // Output: ['key3', 'key4', 'key5'] or something along the lines of this的每个版本，然后列出依赖于该版本的宝石。

Answer 2

我相信问题出在Rails版本和mysql2版本。将包含gem 'mysql2'的Gemfile行更改为gem 'mysql2', '~> 0.4.0'

我已经安装了gem 'rails', '4.2.6'，但显然mysql2和该版本的rails存在一些编译错误。

“对于Rails 4.x，请将gem固定到mysql2'〜> 0.4.0'”-sodabrew

完成此操作后，bundle install便可以运行rails c了。

捆绑器为什么要寻找mysql2 -v'0.4.4'--source'https://rubygems.org/'
