ruby-on-rails - Rails rake 任务显示版本返回错误 Errno::ENOENT: No such file or directory @ rb_sysopen - VERSION

Question

所以像许多人一样，我正在利用“隔离”来尝试学习一些新技能，特别是 rake 任务。

我正在尝试构建一个 rake 任务来对我的 rails 应用程序进行版本控制。我发现了一个 stackoverflow 问题，其答案引起了我的注意，因此我尝试使用它。但是，当我尝试运行任务时，它给了我这个错误。

错误：

╰─ rake version:minor                                                                                                                                                                                                                      ─╯

我知道这告诉我我有一个文件路径错误，但我不能 100% 确定如何解决这个问题，而且我发现的大多数答案对我来说似乎有点混乱。

我要写入的文件路径是：

app/config/initializers/version.rb

从那里我希望能够在我的应用程序的某个地方填充它。

config/initializers/version.rb目前看起来像这样：

module RoadzeWeb
  class Application
    VERSION
  end
end

我的 version.rake 文件如下所示：

def valid?(version)
  pattern = /^\d+\.\d+\.\d+(\-(dev|beta|rc\d+))?$/
  raise "Tried to set invalid version: #{version}" unless version =~ pattern
end

def correct_version(version)
  ver, flag = version.split '-'
  v = ver.split '.'
  (0..2).each do |n|
    v[n] = v[n].to_i
  end
  [v.join('.'), flag].compact.join '-'
end

def read_version
  File.read 'VERSION'
rescue StandardError
  raise 'VERSION file not found or unreadable.'
end

def write_version(version)
  valid? version
  begin
    File.open 'VERSION', 'w' do |file|
      file.write correct_version(version)
    end
  rescue StandardError
    raise 'VERSION file not found or unwritable.'
  end
end

def reset(current, which)
  version, flag = current.split '-'
  v = version.split '.'
  which.each do |part|
    v[part] = 0
  end
  [v.join('.'), flag].compact.join '-'
end

def increment(current, which)
  version, flag = current.split '-'
  v = version.split '.'
  v[which] = v[which].to_i + 1
  [v.join('.'), flag].compact.join '-'
end

desc 'Prints the current application version'
version = read_version
task :version do
  puts <<~HELP
    Available commands are:

    rake version:major            # increment major and reset others x+1.0.0 (keeps any flags on)
    rake version:dev              # set the dev flag on x.x.x-dev

    new_version = if rc
                    [version, "rc#{rc[1].to_i + 1}"].join '-'
                  else
                    [version, 'rc1'].join '-'
                  end
    write_version new_version
    puts "New version release candidate: #{new_version.green}"
  end

  desc 'Removes any version flags'
  task :release do
    version, flag = read_version.split '-'
    write_version version
    puts "Released stable version: #{version.green}"
  end
end

这里的任何帮助将不胜感激！
