当我尝试通过运行rvm pkg install iconv来安装iconv时，它会因此错误而失败：
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：

autoreconf: /usr/bin/autoconf failed with exit status: 1
我该如何解决这个问题？
答案 0 :(得分：6)
尝试：
rvm get head
rvm --skip-autoreconf pkg install iconv
答案 1 :(得分：3)
您不应该使用rvm pkg，RVM 1.19附带autolibs - 这会弃用pkg。
Autolibs将使用包管理器而不是编译来为ruby提取依赖关系，这将改善rubies与系统其他部分的兼容性。
使用autolibs非常简单：
rvm get stable
rvm autolibs enable
rvm install ruby
RVM将安装依赖项，然后构建您需要的ruby。
