我正在使用 JRuby，需要获取特定版本的 gem：

C:\>gem list activerecord-jdbcsqlite3-adapter --remote --all

*** REMOTE GEMS ***

activerecord-jdbcsqlite3-adapter (1.2.6, 1.2.5, 1.2.2.1, 1.2.2, 1.2.1, 1.2.0, 1.1.3, 1.1.2, 1.1.1, 1.1.0, 1.0.3 java, 1.0.2 java, 1.0.1 java, 1.0.0 java, 0.9.7
java, 0.9.6 java, 0.9.5 java, 0.9.4 java, 0.9.3 java, 0.9.2, 0.9.1, 0.9.0.1, 0.9, 0.8.2, 0.8.1)

好的，所以我把它放在 Gemfile 中：

gem 'activerecord-jdbcsqlite3-adapter', '=1.0.3 java'

但是 bundle 并不明白这一点：

C:\bundle install

There was an error in your Gemfile, and Bundler cannot continue.

我究竟做错了什么？

我想你正在寻找：

gem 'activerecord-jdbcsqlite3-adapter', '=1.0.3', :platforms => :jruby

但是，如果您使用的是 jruby，您可能不需要 platfrom 部分。
