JRuby 9.1.12.0（2.3.3） Rubygem 2.6.11 赢7 Mongo 2.3.2 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所有我原来的宝石黄瓜/ 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

这应该有用，也许干净bundle install ...以便您安装最新的宝石：

$ 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
2 gems installed

Answer 2

你正在尝试使用依赖于JRuby中原生扩展的MRI gem - 这不会起作用（很容易）。

您的选择是：

找到一个不依赖于原生扩展的纯ruby mongo驱动程序
找到一个java mongodb驱动程序，你可以将其包装在ruby代码中并在jruby应用程序中作为依赖项加载

Jruby - 无法安装Mongo gem
