JRuby 9.1.12.0 (2.3.3) 红宝石宝石 2.6.11 赢7 Mongo2.3.2 Bson-4.2.2

我已经转移到 JRuby 以使我能够使用一些基于 Java 的库，并且我已经设法安装了我所有的原始 gem cucumber/Rspec/Watir 等，但我似乎无法安装 Mongo Gem。我收到以下错误消息：

C:\Ruby\gem>jruby -S gem install mongo

Answer 1

您正在尝试使用依赖于 JRuby 中的本机扩展的 MRI gem - 这不会（很容易）起作用。

您的选择是：

找到一个不依赖于本机扩展的纯ruby mongo 驱动程序
找到一个 java mongodb 驱动程序，您可以将其包装在 ruby 代码中并作为依赖项加载到您的 jruby 应用程序中

Answer 2

这应该有用，也许做一个干净的 bundle install ...以便您安装最新的 gems :

$ jruby -S gem install mongo
Fetching: bson-4.2.2-java.gem (100%)
Successfully installed bson-4.2.2-java
Fetching: mongo-2.4.2.gem (100%)
Successfully installed mongo-2.4.2
