我的 Rails 应用程序如何接受 RAILS_GEM_VERSION 次要版本更新
我的 Rails 项目在 /config/environment.rb 中有这一行
# Specifies gem version of Rails to use when vendor/rails is not present
RAILS_GEM_VERSION = '2.3.2' unless defined? RAILS_GEM_VERSION
由于我们现在有 2.3.5 作为最新升级，有没有办法让我的environment.rb 接受次要版本更新？
（无需我明确将 2.3.2 更改为 2.3.5）
My rails project has this line in /config/environment.rb
# Specifies gem version of Rails to use when vendor/rails is not present
RAILS_GEM_VERSION = '2.3.2' unless defined? RAILS_GEM_VERSION
As we now have 2.3.5 as the most recent upgrade, is there a way to make my environment.rb accept minor version bumps?
(without I have to explicitly change 2.3.2 to 2.3.5)

不，没有。
您的应用程序需要使用特定的 Rails 版本，主要是因为不同的小版本可能需要额外的步骤来升级框架，例如更改 boot.rb。
No, there isn't.
You application needs to use a specific Rails version mostly because different tiny releases might require additional steps to upgrade the framework such as changes to boot.rb.
自 Rails 2 以来，事情已经发生了一些变化，所以我今天将分享从 5.0.0 到 5.0.0.1 所必须做的事情。
我的
Gemfile读取了gem 'rails', '~>; 5.0.0'。我认为这已经足够了，但是捆绑安装 没有更新任何新内容。所以我尝试用 gem 'rails', '~>; 来强制它。 5.0'当我运行更新时也没有做任何新的事情（注意：这是我自己的实验性应用程序，而不是我正在开发的其他人的应用程序 - 不要只是默认允许次要版本更新来解决像这样的问题；））。所以我不得不尝试其他一些方法来强制执行此安全补丁/修补程序。首先，我必须在本地安装软件包：
gem install Rails --version 5.0.0.1接下来，我更新了捆绑程序：
bundle install...我在输出：
使用rails 5.0.0.1 (was 5.0.0)当我运行
./bin/rakerails:update时，它擦除了我的config/的内容paths.rb 文件更改了我在各种配置文件中的许多设置（其中一些是需要更改的危险安全设置），以及其他一些看似良性的更改。虽然这是预期的行为，但我指出这并不是更新 Rails 次要补丁/修补程序的理想方法。Things have evolved a bit since Rails 2, so Ill share what I had to do to get from 5.0.0 to 5.0.0.1 today.
My
Gemfilereadgem 'rails', '~> 5.0.0'. I figured that was enough, butbundle installwas not updating anything new. So I tried to force it withgem 'rails', '~> 5.0'which also did nothing new when I ran update (note: this is for an experimental app of my own, and not someone else's app I am working on - don't just default to allowing minor version updates to solve problems like this ;) ). So I had to try a few other ways to force this security patch/hotfix.First, I had to install the package locally:
gem install rails --version 5.0.0.1Next, I updated bundler:
bundle install...and I saw this in the output:
Using rails 5.0.0.1 (was 5.0.0)When I ran
./bin/rake rails:update, it wiped the contents of myconfig/routes.rbfile, changed many of my settings in various config files (some of which were dangerous security settings to change), among a few other seemingly benign changes. While this is the expected behavior, I am pointing this out as not exactly a desirable method for updating a minor patch/hotfix for rails.首先，您需要将版本从2.3.5更改为2.3.5，然后运行
Firstly, you need to change the version to 2.3.5 from 2.3.5 and then run
