我尝试克隆this repo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:

gem install nokogiri -v '1.6.2.1'

现在我收到了这个错误:

我尝试关注this answer但我仍然遇到上述错误。

我还尝试再次卸载并安装我的brew(based on this answer),它仍然相同。

此外,我尝试this solution但仍然收到错误。

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。

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

对我有用的(在 macOS Sierra 上)是Sam's answer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

答案 2 :(得分:16)

使用ruby 2.3 1.6.7.2使用代码时,bundle install出现了类似的问题。

对我有用的是添加:

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

bundle install

答案 3 :(得分:13)

如果您正在使用捆绑包:

brew install libxml2

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

我在其他答案中做了所有事情,但还得再做一件事:

  1. 打开Xcode
  2. 点击“同意”
  3. 稍等一下,关闭Xcode
  4. 飘柔

答案 5 :(得分:5)

这似乎是由于nokogiri 1.6.2.1特定问题。

我在我的Gemfile中添加了这个:

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

然后运行bundle update nokogiri,然后bundle。现在一切都很好。

尝试一下

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

然后安装Nokogiri

sudo gem install nokogiri

答案 7 :(得分:2)

Spencer's回答对我有用,但我还需要使用-n参数来克服记录的权限问题here.

所以最后,对我有用的命令是:

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

在rbenv gem文件夹中删除nokogiri并重新安装为我解决了这个问题。

答案 9 :(得分:0)

我有类似的问题。原因已过时xcode

如果您运行brew doctor,您可能会看到它。只需打开AppStore,即可转到updates标签并更新您的xcode。

答案 10 :(得分:0)

在更新到xcode 10时遇到相同的问题,我通过以下步骤解决了该问题:

  1. xcode-select --install
  2. 捆绑安装--deployment
  3. gem安装nokogiri

答案 11 :(得分:0)

如果以上方法均无效, 尝试删除Gemfile.lock,然后重新安装gem。

这帮助我解决了这个问题

  • 我重新安装了Xcode并将xcode-select定向到其路径
sudo xcode-select -s /Applications/Xcode.app/Contents/Developer
