当我尝试在Mac OS X 10.6上的nokogiri上安装ruby-1.8.7-p334 [ x86_64 ] gem时，出现以下错误：

sudo gem install nokogiri

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more

Answer 1

在安装nokogiri gem之前，您需要安装库。以下是使用自制程序

执行此操作的步骤

# the rest of this snippet assumes installation of libxml 2.7.7. YMMV.
brew install libxml2
brew link libxml2

# install libxslt from source
wget ftp://xmlsoft.org/libxml2/libxslt-1.1.26.tar.gz
tar -zxvf libxslt-1.1.26.tar.gz
cd libxslt-1.1.26
./configure --prefix=/usr/local/Cellar/libxslt/1.1.26 \
            --with-libxml-prefix=/usr/local/Cellar/libxml2/2.7.7
make
sudo make install

gem install nokogiri -- --with-xslt-dir=/usr/local/Cellar/libxslt/1.1.26

使用macports

sudo port install libxml2 libxslt
sudo gem install nokogiri

Answer 2

我尝试了各种我能找到的解决方案，包括：。使用brew来安装libxslt / libxml2 / libiconv 。尝试使用各种--with-configurations进行gem安装遗憾的是，在我卸载MacPort和所有已安装的端口之前，它们都不适合我。

然后只需执行命令gem install nokogiri，gem和rdoc就像轻而易举地安装好了。

我不明白为什么会这么详细，但根据我自己使用MacPort的经验（导致安装了多套ruby / rake / gem）以及比较brew和port的文章，我不会去回到港口。

在ruby-1.8.7-p334 [x86_64]上使用rvm安装nokogiri gem时出错
