配置：

  • macOS High Sierra 10.13.3
  • Xcode 9.2（已安装开发工具）
  • gem 2.7.6

注意：我的错误完全相同：

sudo gem install nokogiri -n /usr/local/bin

答案 0 :(得分：11)

从mkmf.log中，我得到了一个提示：

  

警告：文件的非便携式路径＆＃39;＆lt; String.h＆gt;＆＃39 ;;指定的路径与磁盘上的文件名不同

实际上，错误来自/usr/local/include/String.h文件，该文件可能不是预期的<String.h>文件。这个文件很神秘，因为它想要包含<plist/Node.h>，但/usr/local/include/plist/不存在。

实际上，我发现了其他一些有趣的东西：

brew doctor
  

警告：在/ usr / local / include中找到了未提取的头文件。   如果你没有故意将它们放在那里，那么它们可能会导致问题   构建Homebrew公式，可能需要删除。

     

意外的头文件：
    ...
    /usr/local/include/String.h
    ......

所以我只列出了那些意外的头文件：

brew doctor 2> doctor.txt

我手动修剪了doctor.txt的顶级内容，只保留文件列表。然后我删除了那些：

sed 's/^  //g' doctor.txt | tr "\n" "\0" | xargs -0 rm
rm doctor.txt

然后修复了两个安装问题（libxml-ruby和nokogiri）。
