[英]Set ruby version in Gemfile
I can set ruby version in Gemfile
as follows: 我可以在Gemfile
设置ruby版本,如下所示:
ruby '2.0.0'
But what if I want to have a particular version as 2.0.0-p353
? 但是如果我想要一个特定的版本为2.0.0-p353
怎么2.0.0-p353
?
When I add it to Gemfile
, I get: 当我将它添加到Gemfile
,我得到:
Your Ruby version is 2.0.0, but your `Gemfile` specified 2.0.0-p353
Is it even possible to set a particular version? 甚至可以设置特定版本?
In Version 1.3 and earlier of Bundler you couldn't specify the patchlevel : 在Bundler的1.3版及更早版本中,您无法指定补丁级别 :
The
ruby
directive explicitly leaves out the ability to specify a patch level.ruby
指令明确地省去了指定补丁级别的能力。 Ruby patches often include important bug and security fixes and are extremely compatible. Ruby补丁通常包含重要的错误和安全修复程序,并且非常兼容。
This changed in version 1.5, the docs now say : 这在版本1.5中发生了变化, 文档现在说 :
In the
ruby
directive,:patchlevel
is optional, as patchlevel releases are usually compatible and include important security fixes. 在ruby
指令中,:patchlevel
是可选的,因为补丁级别版本通常是兼容的并包含重要的安全修复程序。 The patchlevel option checks theRUBY_PATCHLEVEL
constant, and if not specified then bundler will simply ignore it. patchlevel选项检查RUBY_PATCHLEVEL
常量,如果未指定,则bundler将忽略它。
So you can specify the patchlevel like this: 所以你可以像这样指定补丁级别:
ruby '2.0.0', :patchlevel => '353'
If anyone is looking to be reminded of how to NOT specify a minor version, (yeah call me a noob) you could do: 如果有人想要提醒如何不指定次要版本,(是的,我称之为菜鸟)你可以这样做:
ruby ">=2.2"
which would allow 'bundle install' call with ruby 2.2.4. 这将允许与ruby 2.2.4进行“捆绑安装”调用。
