我已经尝试安装

rvm pkg install readline
rvm pkg install iconv
rvm install 1.8.7
rvm use 1.8.7 

即使尝试过 为什么在 Mac 操作系统上安装 Nokogiri 会失败并缺少 libiconv？。

什么都不起作用。请帮忙！

谢谢！

Answer 1

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

要解决此问题，请在 Gemfile 中添加以下内容：

gem "iconv", "~> 1.0.3"

然后运行 ​​bundle install。

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

Answer 2

对于那些使用 rbenv 而不是 rvm

$ which iconv
$ /usr/local/bin/iconv

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

​​ 祝你好运

（作为一面请注意，据报告此错误发生在 Ruby 1.8.7-p3xx 中）
