Question

我尝试使用 bundle 安装，但出现错误。我安装了 zlib。

Fetching nokogiri 1.7.0.1


Your user account isn't allowed to install to the system RubyGems.
  You can cancel this installation and run:

      bundle install --path vendor/bundle

  to install the gems into ./vendor/bundle/, or you can enter your password
  and install the bundled gems to RubyGems using sudo.

An error occurred while installing nokogiri (1.7.0.1), and Bundler
cannot continue.
Make sure that `gem install nokogiri -v '1.7.0.1'` succeeds before bundling.

Answer 1

您的错误似乎来自 zlib:

zlib is missing; necessary for building libxml2

根据 this 的讨论，安装软件包似乎可以解决问题：

为 Ubuntu

sudo apt-get install zlib1g-dev

然后尝试安装 nokogiri:

gem install nokogiri -v '1.7.0.1'

Answer 2

虽然问题是关于 Ubuntu，但我运行进入 MacOS 的错误，这对我有用：

对于MacOS蒙特雷

bundle config build.nokogiri --use-system-libraries
bundle install

问题出在 libxml 上：

libxml2 is missing. Please check the mkmf.log to check how it is failing.
