Question

我试图在我的Rails应用程序上进行捆绑安装，并且它被困在“安装nokogiri”。错误消息底部的说明说明

Make sure that `gem install nokogiri -v '1.5.5'` succeeds before bundling.

有一次我看到了，我试过了

gem install nokogiri -v '1.5.5'

它告诉我安装Nokogiri时出错。我在Mac上使用Ruby 1.9.2，在Rails 3.0.4应用程序中。

有人可以建议修复吗？

An error occurred while installing nokogiri (1.5.5), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.5.5'` succeeds before bundling.

brew doctor说没有问题。 brew update表示所有内容都已更新。当我brew install libxslt libxml2 libiconv时，我收到此错误：

Error: No available formula for libiconv
Apple distributes libiconv with OS X, you can find it in /usr/lib.
Some build scripts fail to detect it correctly, please check existing
formulae for solutions.

当我尝试gem install nokogiri时，我收到此错误：

Answer 1

假设您尚未安装Homebrew：

ruby -e "$(curl -fsSkL raw.github.com/mxcl/homebrew/go)"

brew doctor

确保一切正常

brew update

为了能够安装libiconv

brew tap homebrew/dupes

brew install libxslt libxml2 libiconv
brew link libxslt libxml2 libiconv

gem install nokogiri

Answer 2

如果您使用的是Ubuntu，请尝试：

sudo apt-get install libxslt-dev libxml2-dev
gem install nokogiri

如果您使用的是Mac OS，请尝试“Why does installing Nokogiri on Mac OS fail with libiconv is missing?”。

Answer 3

对我来说，这些问题已解决：

bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java

gem install nokogiri

Shows this message on "bundle update"

捆绑安装在Nokogiri停止了
