ruby-on-rails - 在 Gemfile 中设置 ruby​​ 版本

Question

我可以在 Gemfile 中设置 ruby​​ 版本如下:

ruby '2.0.0'

但是如果我想要一个特定的版本作为 2.0.0-p353 怎么办？

当我将它添加到 Gemfile 时，我得到:

Your Ruby version is 2.0.0, but your `Gemfile` specified 2.0.0-p353

甚至可以设置特定版本吗？

Answer 1

在 Bundler 1.3 及更早版本中，您 couldn’t specify the patchlevel :

The ruby directive explicitly leaves out the ability to specify a patch level. Ruby patches often include important bug and security fixes and are extremely compatible.

这在 1.5 版中发生了变化，the docs now say :

In the ruby directive, :patchlevel is optional, as patchlevel releases are usually compatible and include important security fixes. The patchlevel option checks the RUBY_PATCHLEVEL constant, and if not specified then bundler will simply ignore it.

所以你可以像这样指定补丁级别:

ruby '2.0.0', :patchlevel => '353'
