WEBrick rails 服务器无法启动 [英] WEBrick rails server won't start
本文介绍了WEBrick rails 服务器无法启动的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
你能推荐一个修复方法吗?
我根据其他 SE 问题尝试过的补救措施:
- 运行捆绑安装
- 运行 gem 清理
- 运行 bundle exec rails server
- 运行 sudo ln -s/usr/local/mysql/lib/libmysqlclient.18.dylib/usr/lib/libmysqlclient.18.dylib
- 删除 root 密码(以匹配 database.yml 配置文件)
已安装:
- OSX 10.8.3
- Ruby 2.0.0p0
- Rails 3.2.13
- mysql2 gem 0.3.11
- Gemfile 中的'mysql2'
- Mysql 14.14 5.6.11
复制:
- 起始位置:~/Sites/simple_cms
- 运行rails 服务器"
然后我得到以下输出:
=> Booting WEBrick
=> Rails 3.2.13 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server

推荐答案
您是否运行 rake db:create 来创建数据库?之后，rails server 应该可以工作了.
