OSX 10.7.5 - Ruby on Rails 加载错误: 无法打开库 'sodium': dlopen(sodium, 5)

Question

在输入 rake db:create 后，我收到以下信息：

LoadError: Could not open library 'sodium': dlopen(sodium, 5): image not found.
Could not open library 'libsodium.dylib': dlopen(libsodium.dylib, 5): image not found

这里有更多的输出。

Answer 1

您可能没有安装sodium密码库。如果您使用的是MacPorts，请使用以下命令进行安装：

sudo port install libsodium

或者使用Homebrew：

brew install libsodium
