[我是不熟悉ruby的人。执行rake db:create时出现以下错误。是什么问题。我发现这是一个常见问题，然后用谷歌搜索。我发现更改了rake版本，但问题没有解决。
rake aborted!

1.10 Update your Bundler
bundle install
1.11 :Edit your rake file from fedena project
vi fedena-v2.3-bundle-linux/Rakefile
Replace require 'rake/rdoctask' to require 'rdoc/task'
1.12 :Downgrade Your gem latest version to 1.3.7
gem update --system 1.3.7
1.13 :Now there will be a bundler conflict(latest version of gem and gem version 1.3.7) you should solve this using uninstalling bundler
Uninstalling bundler
rvm @global
gem list -d bundler1.5.2
rvm gemset use global && gem install bundler
bundle install
gem uninstall bundler(Uninstall all bundler which are installed)
1.14 Set up Fedena databases
From the Fedena source directory in terminal run, "rake db:create" followed by, "rake fedena:plugins:install_all"
1.15 Change permissions for scripts
From the same directory grant executable permissions for the files in script directory by,
"chmod +x script/*"
1.16 Run the inbuilt server
If everything went fine till now, you are ready to run fedena server by running the following from fedena source folder,
"script/server"
1.17 Finally, run the command "script/server".
This would start the server and it will be accessible at http://localhost:3000
[2在Ubuntu中安装Fedena
2.1 Setting up the Rails development environment
Ruby, rubygems, rails and other required packages can be installed by :
sudo apt-get install irb libopenssl-ruby libreadline-ruby rdoc ri ruby ruby-dev
cd /usr/local/src
wget http://production.cf.rubygems.org/rubygems/rubygems-1.3.7.tgz
tar xzvf rubygems-1.3.7.tgz
cd rubygems-1.3.7
sudo ruby setup.rb
sudo update-alternatives --install /usr/bin/gem gem /usr/bin/gem1.8 1
sudo gem install rails -v 2.3.5
2.2 Setting up MySQL server
Fedena uses mysql, so run,
"sudo apt-get install libmysqlclient-dev mysql-server"
Do remember the mysql password you set during this step, it is required in step five.
2.3.Download the latest Fedena source code from github
Download Fedena source code from GitHub. Extract the downloaded .zip archive to a convenient location where you would be running fedena . Let us say we extracted it to a directory named fedena in my home(~) directory.
2.4.Setup your database details in the database.yml
Open the file database.yml in the config folder of the fedena soucre. Change the following details:
database: fedena - The name of the database you want to use for fedena
username: root - Mysql username for fedena
password: mypass - The password for the above mysql user
2.5.Install the rest of the gems
"gem install declarative_authorization -v 0.5.1"
"gem install i18n -v 0.4.2"
2.6 Downgrade your rake version to 10.1.0 to rake, version 0.9.2
3. gem uninstall rake -v 10.1.0
4. gem install rake -v 0.9.2
2.7 Edit your rake file from fedena project
vi fedena-v2.3-bundle-linux/Rakefile
Replace require 'rake/rdoctask' to require 'rdoc/task'
2.8. Set up Fedena databases
From the Fedena source directory in terminal run, "rake db:create" followed by, "rake fedena:plugins:install_all"
2.9 Change permissions for scripts
From the same directory grant executable permissions for the files in script directory by,
"chmod +x script/*"
2.10 Run the inbuilt server
If everything went fine till now, you are ready to run fedena server by running the following from fedena source folder,
"script/server"
仅需要将您的rake从10.x.x降级到1.8.7
这是您的操作方式：
gem卸载耙
gem install rake -v = 1.8.7

实际上，由于过时的Rails版本，安装Fedena很痛苦。
