我试过安装

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

甚至尝试过为什么在Mac OS上安装Nokogiri失败并且libiconv丢失了？.

什么都行不通.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

要解决它,请在Gemfile中添加:

gem "iconv", "~> 1.0.3"

然后跑bundle install.

注意:iconv已被弃用了一段时间.它由(builtin)String#encode代替.

Answer 2

对于那些使用rbenv而不是rvm的人

$ 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

祝好运

(作为旁注,据报道这个错误发生在Ruby 1.8.7-p3xx中)
