Question

Gemfile只包含rails 3.0.7和sqlite3，突然rake不会在任何app上运行。运行'rake db：migrate'时出错完整跟踪输出：

rake aborted!

Answer 1

我做了：sudo gem uninstall rake -v 0.9然后将gem 'rake', '0.8.7'添加到我的gem文件中。

Answer 2

您可以通过添加以下行来修复您的application.rb文件，而不是降级您的Rake：

include Rake::DSL

只需在类Application中添加它，你应该很好！

示例application.rb：

module AppName
  class Application < Rails::Application
   include Rake::DSL
  end
end

Answer 3

Gemfile中的

gem 'rake', '0.8.7'如果捆绑包抱怨rake lock'0.9.0'，则可能还需要运行bundle update rake。

以下是rake github页面https://github.com/jimweirich/rake/issues/33

上的问题

Answer 4

我在jruby。以下是解决问题的确切命令。

jruby -S gem uninstall rake
jruby -S gem install rake -v 0.8.7

编辑Gemfile：在gem'trail'之后添加：

gem 'rake', '0.8.7'

最后运行：

jruby -S bundle update rake

Answer 5

在命令提示符下运行这两行。它将删除rake 0.9.0。用你的用户名替换它显示“用户名”

GEM_HOME ='/ Users/username/.rvm/gems/ruby-1.9.2-p180@global'GEM_PATH='/Users/username/.rvm/gems/ruby-1.9.2-p180@global'gemony卸载rake

GEM_HOME ='/ Users / username / .rvm / gems / ruby-1.9.2-p180'GEM_PATH ='/ Users / username / .rvm / gems / ruby-1.9.2-p180'gem uninstall rake

然后安装正确的宝石：

rvm gem install mysql2 -v 0.2.7

rvm gem install rake -v 0.8.7

更新MySQL gem（此处显示x86_64 intel安装的声明）：

env ARCHFLAGS =“ - arch x86_64”gem install mysql - --with-mysql-config = / usr / local / mysql / bin / mysql_config

创建新应用时：

rails new -d mysql

您不需要更改gemfile或使用bundle exec

我希望这是有道理的。这篇文章不会让我将语法布局在可读的地方。
