问题描述
我一直按照中的文档来解决Nokogiri安装问题。 tutorial。
但是这一次，即使安装了所有依赖关系之后，Nokogiri还没有安装。我收到以下错误：
缺少libxml2。请访问< http：//nokogiri.org/tutorials/installing_nokogiri.html>
我试着通过指定libxml2和libxslt目录来安装它：
sudo gem install nokogiri - --with-xml2-include = / usr / include / libxml2 --with-xml2-lib = / usr / lib --with -xslt-dir = / usr /
但它返回相同的错误。
我遵循了所有其他相关的Stack Overflow文章，没有任何帮助。有没有人有解决方案？
首先，安装依赖关系：
sudo apt-get install libxslt-dev libxml2-dev
如果你仍然收到错误，你可能会缺少一个编译器工具链：
sudo apt-get install build-essential
如果缺少构建工具链，您将会看到libxml2 is missing在Debian Lenny上遇到这个问题）。
Nokogiri构建测试 - 编译一个libxml2头文件以验证它是否存在，但是它不区分 libxml2丢失和编译器测试libxml2丢失。
I always worked my way around Nokogiri installation issues by following the documentation in the "Installing Nokogiri" tutorial.
But this time, even after installing all the dependencies, Nokogiri hasn't been installed. I get the following error:
libxml2 is missing. please visit <http://nokogiri.org/tutorials/installing_nokogiri.html>
I tried installing it by specifying the libxml2 and libxslt directories:
sudo gem install nokogiri -- --with-xml2-include=/usr/include/libxml2 --with-xml2-lib=/usr/lib --with-xslt-dir=/usr/
but it returned the same error.
I followed all the other related Stack Overflow articles and none helped. Does anyone have a solution?
First, install the dependencies:
sudo apt-get install libxslt-dev libxml2-dev
If you still receive the error, you may be missing a compiler toolchain:
sudo apt-get install build-essential
You'll get the "libxml2 is missing" error if you're missing a build toolchain (at least I ran into this issue on Debian Lenny).
The Nokogiri build test-compiles a libxml2 header file to verify that it is present, however, it doesn't differentiate between "libxml2 is missing" and "a compiler to test libxml2 is missing".
这篇关于Nokogiri安装失败-libxml2丢失的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
