当我尝试通过运行安装 iconv 时：rvm pkg install iconv失败并出现以下错误：
Error running 'autoreconf -is --force',
please read /usr/local/rvm/log/libiconv/autoreconf.log
Configuring libiconv in /usr/local/rvm/src/libiconv-1.13.1.........................

Please note that it's required to reinstall all rubies:
rvm reinstall all --force
在日志中，它说：
