Question

我遇到了同样的问题，大多数人在后小牛升级机上使用nokogiri安装时遇到了这个问题。

我的configure.log显示以下错误：

configure: error: cannot find sources (entities.c) in /usr/local/lib/node_modules/npm or ..

我已尝试安装/重新安装/取消链接/重新链接libxml2，libxslt。

还有其他提示吗？谢谢！

Answer 1

使用Homebrew安装库并在安装gem之前设置NOKOGIRI_USE_SYSTEM_LIBRARIES=1对我来说很有用。

汇总：

如果以前安装过，请卸载gem：
$ gem uninstall nokogiri
使用Homebrew安装libxml2，libxslt和libiconv：
$ brew install libxml2 libxslt libiconv
安装gem，指定要链接的库的路径：
$ NOKOGIRI_USE_SYSTEM_LIBRARIES=1 gem install nokogiri -- --use-system-libraries --with-iconv-dir="$(brew --prefix libiconv)" --with-xml2-config="$(brew --prefix libxml2)/bin/xml2-config" --with-xslt-config="$(brew --prefix libxslt)/bin/xslt-config"

有完全相同的问题。我锁定了它为什么在

中寻找（entities.c）

/usr/local/lib/node_modules/npm or ..

我不是专家，但是npm可能没有make文件。

我通过从〜/ .bash_profile删除npm来安装nokogiri（另一个要检查的地方可能是〜/ .profile）。这是我的.bash_profile看起来的样子：

export PATH="/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/lib/node_modules/npm:/usr/local/mysql/bin:$PATH"

### Added by the Heroku Toolbelt
export PATH="/usr/local/heroku/bin:$PATH"

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*

if [ -f `brew --prefix`/etc/bash_completion ]; then
    . `brew --prefix`/etc/bash_completion
fi

source ~/.profile

你可以在第一行看到npm，我刚刚删除了它，重新加载了我的终端（所以它停止在npm目录中寻找东西）并且做了sudo gem install nokogiri和IT工作：）!!!

作为旁注，npm命令似乎正在工作，所以我不知道为什么我在.bash_profile中有这条路径

希望这有帮助，首先回答SO。

这是我通过brew安装Yosemite和libxml2的解决方案

gem install nokogiri -v '1.6.5' -- --use-system-libraries=true --with-xml2-include=/usr/include/libxml2

在小牛升级后安装nokogiri - entities.c失踪了吗？
