问题描述
似乎这个问题的最后一个帖子由于某种原因被关闭，所以我会试试我的运气...
Seems the last post for this problem was closed for one reason or another so I'll try my luck...
我正在尝试运行一个简单的rake db:migrate"命令.当我这样做时，我收到标题中的错误.是的，解决方案看起来"很明显，但这并不是因为我的 Rakefile 不包含对rake/rdoctask"的任何引用.它似乎来自documentation.rake，但是当我尝试按照错误建议更改该文件时，我收到了不同的错误.我发现有几篇帖子宣称这是一个已知问题，但我没有发现任何内容表明如何修复或解决此问题.
I'm trying to run a simple "rake db:migrate" command. When I do, I get the error in the title. Yes, the solution "appears" obvious but it's not because I don't my Rakefile does not contain any references to 'rake/rdoctask'. It seems to be coming from documentation.rake but when I try to change that file as recommended by the error, I get a different error. I have found a couple of posts declaring this to be a known issue but nothing I've found indicates how to fix or work around this.
有没有人有任何想法如何解决它?下面是带有 --trace 的 rake 命令的输出:
Does anyone have any ideas how to fix it? Below is the output from the rake command with a --trace:
$ rake --trace db:migrate
rake aborted!

我发现我的 Gemfile 中有 rails 3.0.3，所以我将其更改为 3.2.9，但是现在当我运行 rake db:migrate 时，我得到:
I discovered that I had rails 3.0.3 in my Gemfile so I changed it to 3.2.9, but now when I run rake db:migrate I get:
rake aborted!
Bundler could not find compatible versions for gem "rack":
In Gemfile:
rails (= 3.2.9) x86-mingw32 depends on
rack (~> 1.4.0) x86-mingw32
rack (1.2.5)
我不确定错误是什么意思，但gem list rack"显示我同时安装了 1.4.1 和 1.4.0.我的 Gemfile 非常简单:
I'm not sure what the error means but "gem list rack" shows I have both 1.4.1 and 1.4.0 installed. My Gemfile is pretty simple:
gem 'rails', '3.2.9'
gem 'rack','< 1.4.1'
gem 'mysql2', '< 0.3'
有什么想法吗?
推荐答案
我在使用 rails 2.3.5 时遇到了类似的问题，因此按照跟踪消息中的指示，我编辑了 Rakefile 以要求使用 'rdoc/task' 而不是 rake/rdoctask并安装了 rdoc gem.
I had similar problem using rails 2.3.5 so as instructed in the trace message I have edited the Rakefile to require 'rdoc/task' instead of rake/rdoctask and installed rdoc gem.
如果您使用 rake 版本 > 10.0.0 .请编辑您的 Rakefile
If you are using rake version > 10.0.0 . please edit your Rakefile
来自:
require 'rake'
require 'rake/testtask'
require 'rake/rdoctask'
require 'tasks/rails'
到:
require 'rake'
require 'rake/testtask'
require 'rdoc/task'
require 'tasks/rails'
如果你不想编辑 Rakefile，你可以像这样切换回旧版本的 take
If you don't want to edit the Rakefile you can switch back to older version of take like this
gem uninstall rake -v 10.0.3
gem install rake -v 0.8.7
这篇关于错误:'rake/rdoctask' 已过时且不再受支持.改用“rdoc/task"(在 RDoc 2.4.2+ 中可用)的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
