An error occurred while installing nokogiri (1.6.7.2), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.6.7.2'` succeeds before bundling.

正如它所暗示的，然后我运行gem install nokogiri -v '1.6.7.2'，它安装得很好。我重复bundle update 并得到与以前相同的错误。当我执行nokogiri --version 时，它会以 1.6.7.2 的形式返回：

$ nokogiri --version

有什么建议吗？这似乎不是 nokogiri 问题，而是 github-pages 或 bundler 问题（当然，我也可能是问题！）

【问题讨论】：

见过this?
谢谢@D-side - Geoff's comment 成功了。这是我为使其正常工作所做的工作...@ 987654330@。不知道如何将其发布为答案 - 但请随时自行发布，我会给你信用。

【解决方案1】：

问题在于扩展构建过程由于某种原因无法找到libiconv。

周围的每个人似乎都建议为 RubyGems 使用额外的参数，但问题明确指出 gem 单独实际上可以很好地安装有问题的 gem。因此，这与 Bundler 的 gems 束 的配置方式有关。

您可以通过using bundle config 将配置应用于此特定捆绑包：
```
bundle config build.nokogiri --use-system-libraries
```
这大致告诉 Bundler “无论何时安装 nokogiri，添加 --use-system-libraries”。
...然后继续：
```
bundle update
```

感谢this answer背后的优秀人士。

【解决方案2】：

您的捆绑包尝试将 gem 安装到 vendor/bundle 而不是系统 gem，这意味着您可能尝试了 --path vendor/bundle 或 --deployment - 请参阅 cat .bundle/config

您可以通过运行 bundle install --system 重新使用系统 gems

【讨论】：

@PatS 这很奇怪 - 当 gem 已经安装并且 bundle 正在使用系统 gem 时，它不应该重新安装，你使用 rvm 还是其他 ruby 管理器？

【解决方案3】：

试试下面的代码。

gem install nokogiri -- --use-system-libraries

【解决方案4】：

我认为在您解决此问题之前，许多程序员都面临同样的问题，如果您在stackoverflow 上提出任何问题，请确保有或没有此类问题。反正try this

gem install pg -- --with-pg-config= 'PATH_TO_YOUR_PG_CONFIG'

谢谢
