乘客 (nginx) 上的 Redmine 无法启动

Question

我按照以下教程进行操作： http://redminecrm.com/boards/4/topics/448-installing-redmine-2-2-passenger-nginx-rvm-on-ubuntu-12-04

起初，我遇到了 mysql2 的问题，但通过编辑 Gemfile 并运行包更新来修复它。之后，我遇到了一个新问题。下面附上回溯。我希望有人可以帮助我解决这个问题。

我正在使用 Ruby 2.0.0p0、passenger-4.0.0.rc6、nginx 1.2.7。

Answer 1

阅读日志！

没有要加载的文件 -- iconv (LoadError)

在你的系统上安装 iconv，然后安装 iconv gem

gem install iconv

Answer 2

in `require': no such file to load -- iconv (LoadError)

我已经解决了：

它显示 iconv 不存在，但 iconv 已安装在我的生产环境中。

root@AY130/current# iconv --version

iconv (Ubuntu EGLIBC 2.15-0ubuntu10.4) 2.15

如何解决：

安装

gem "iconv", "~> 1.0.3" #在你的 Gemfile 中添加了这个

iconv 已被弃用一段时间。它被（内置）String#encode 替换
