It shows that the iconv not exist but the iconv has installed in my production env.
它显示 iconv 不存在，但 iconv 已安装在我的生产环境中。

To resolve it, add this in your Gemfile:
要解决它，请将其添加到您的 Gemfile 中：
gem "iconv", "~> 1.0.3"
Then run bundle install.
然后运行bundle install。
Note: iconv has been deprecated for a while. It is replaced by (builtin) String#encode
See here: https://bbs.archlinux.org/viewtopic.php?id=160369
注意： iconv 已被弃用一段时间。它被（内置）String#encode 替换

For those using rbenvinstead of rvm
对于那些使用rbenv而不是 rvm 的人
$ which iconv
$ /usr/local/bin/iconv
Then use the directory location of iconv to reinstall ruby
然后使用iconv的目录位置重新安装ruby
$ CONFIGURE_OPTS="--with-iconv-dir=/usr/local" rbenv install 1.8.7-p358
Good luck
祝你好运
