遵循了很多在网络上找到的帮助之后，包括使用brew来构建和安装libxml2和libxslt以及从源中构建libiconv(如"

After following a lot of help found around the web including building and installing libxml2 and libxslt using brew and building libiconv from the sources (as described in "Installing Nokogiri"), the error remains the same.

当尝试为Nokogiri运行安装时，似乎可以找到libxml2和libxslt，但不能找到libiconv.

When trying to run the installation for Nokogiri, libxml2 and libxslt seem to be found fine, but not libiconv.

任何对这些事情有更深入了解的人都知道如何安装Nokogiri?

Anyone with a better knowledge of these things know how to get Nokogiri installed?

推荐答案

我遇到了同样的问题.不幸的是，"安装Nokogiri "没有涵盖Iconv问题.这是我解决问题的方法.

I had the same issue. Unfortunately the "Installing Nokogiri" doesn't cover Iconv issues. Here's how I resolved the issue.

首先安装自制软件，它将使您的生活更轻松.如果您已经安装了它，请确保通过如下更新来获取最新的公式:

First install homebrew, it'll make your life easier. If you already have it installed, be sure to grab the latest formulae by updating like so:

brew update

注意:在OSX 10.9+中，您可能需要安装xCode命令工具以允许您安装libiconv.

Note: In OSX 10.9+ you may need to install xCode command tools to allow you to install libiconv.

xcode-select --install

然后安装更高版本的libiconv

then install a newer version of libiconv

brew install libiconv

然后安装您的宝石

gem install nokogiri -- --with-iconv-dir=/usr/local/Cellar/libiconv/1.14
