安装nokogiri时出错:无法构建gem原生扩展并且缺少libiconv(OSX)

Question

我尝试克隆这个仓库并运行bundle install.捆绑过程失败并抛出此错误:

    ...

    An error occurred while installing nokogiri (1.6.2.1), and Bundler cannot continue.
    Make sure that `gem install nokogiri -v '1.6.2.1'` succeeds before bundling.

然后我尝试运行这个:

gem install nokogiri -v '1.6.2.1'

现在我收到这个错误:

我试着按照这个答案,但我仍然得到同样的错误.

我也尝试再次卸载并安装我的brew(根据这个答案),它仍然是相同的.

此外,我尝试这个解决方案,但仍然得到错误.

我现在该怎么做才能确保成功安装这个nokogiri gem？

注意:我使用的是OSX 10.11.1 El Capitan.

Answer 1

运行以下命令:

gem uninstall nokogiri
xcode-select --install
gem install nokogiri

有时mac更新可能会破坏xcode CLI,因此重新安装可以解决问题:https: //github.com/sparklemotion/nokogiri/issues/1445

Answer 2

对我有用的(在macOS Sierra上)是Sam的回答和以下内容的组合:

gem install nokogiri -- --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.12.sdk/usr/include/libxml2 --use-system-libraries

Answer 3

在使用ruby 2.3进行代码处理1.6.7.2时,我遇到了类似的问题bundle install.

对我有用的是添加:

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

之前

bundle install

Answer 4

如果你正在使用bundle:

brew install libxml2

# If using Bundle
bundle config build.nokogiri --use-system-libraries \
  --with-xml2-include=$(brew --prefix libxml2)/include/libxml2
bundle install

Answer 5

我在其他答案中做了一切,但还得做一件事:

1. 打开Xcode
2. 点击"同意"
3. 稍等一下,关闭Xcode
4. 麾

Answer 6

尝试这个

sudo apt-get install build-essential patch ruby-dev zlib1g-dev liblzma-dev

然后安装Nokogiri

sudo gem install nokogiri

Answer 7

似乎是由于nokogiri 1.6.2.1特定的问题。

我将其添加到我的Gemfile中：

gem 'nokogiri', '~> 1.6', '>= 1.6.7'

并运行bundle update nokogiri，然后bundle。现在一切正常。
