在网上找到了很多帮助之后，包括使用 brew 构建和安装 libxml2 和 libxslt 以及从源代码构建 libiconv(如安装 Nokogiri")，错误依旧.

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.

当尝试运行 Nokogiri 的安装时，libxml2 和 libxslt 似乎正常，但 libiconv 不行.

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

对这些事情有更好了解的人知道如何安装 Nokogiri 吗?

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"不包括 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，它会让您的生活更轻松.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 命令工具才能安装 libiconv.

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

xcode-select --install

然后安装新版本的 libiconv

then install a newer version of libiconv

brew install libiconv

然后安装您的 gem

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