Question

我有问题尝试捆绑安装nokogiri 1.7.2

我在用

gem 'rails', '4.2.4'
MacOS High Sierra version 10.13.6

我不知道出了什么问题

下面是我的错误输出:

完整错误输出:

这是错误描述的地方:

An error occurred while installing nokogiri (1.7.2), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.7.2'` succeeds before bundling.

In Gemfile:
  rails_admin was resolved to 1.1.1, which depends on
    rails was resolved to 4.2.4, which depends on
      actionmailer was resolved to 4.2.4, which depends on
        actionpack was resolved to 4.2.4, which depends on
          actionview was resolved to 4.2.4, which depends on
            rails-dom-testing was resolved to 1.0.8, which depends on
              nokogiri

更新,没有使用sudo gem install nokogiri

$ sudo gem install nokogiri -v '1.7.2'
Building native extensions.  This could take a while...

Building Nokogiri with a packaged version of libxml2-2.9.4
with the following patches applied:
    - 0001-Fix-comparison-with-root-node-in-xmlXPathCmpNodes.patch
    - 0002-Fix-XPointer-paths-beginning-with-range-to.patch
    - 0003-Disallow-namespace-nodes-in-XPointer-ranges.patch

Team Nokogiri will keep on doing their best to provide security
updates in a timely manner, but if this is a concern for you and want
to use the system library instead; abort this installation process and
reinstall nokogiri as follows:

    gem install nokogiri -- --use-system-libraries
        [--with-xml2-config=/path/to/xml2-config]
        [--with-xslt-config=/path/to/xslt-config]

If you are using Bundler, tell it to use the option:

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

Note, however, that nokogiri is not fully compatible with arbitrary
versions of libxml2 provided by OS/package vendors.

Answer 1

有时也会发生在我身上，在这种情况下，我只需gem install nokogiri -v '1.7.2'按照错误提示通过安装 nokogiri 即可。如果失败，gem uninstall nokogiri -v '1.7.2'请先尝试，然后重试...

正如 xploshioOn 所提到的，sudo gem install作为最后的手段使用。
