不能在CentOS上安装Nokogiri，而不需要更高的Ruby版本?

Below is what I tried on my CentOS6.5 server. I have already updated Git and Ruby, but still can't get it to install. The first section is where I tried to install it as a sudo user. The second section is when I Tried to install it by root.

下面是我在CentOS6.5服务器上的尝试。我已经更新了Git和Ruby，但是仍然无法安装。第一部分是我试图将其安装为sudo用户的地方。第二部分是当我尝试安装它的根。

Can anyone offer other ideas on how to fix this? I am having a hard time finding any fixes for this issue.

有人能提出其他的解决方法吗?我很难找到解决这个问题的方法。

3 个解决方案

#1

yum install libxslt-devel libxml2-devel
bundle config build.nokogiri --use-system-libraries
bundle install

#2

These error messages appear to me to be pretty clear-cut: you're using an old ruby in the first instance (and running into Rubygems behavior (not Nokogiri behavior)), and trying to link to an old (known-buggy) version of libxml2 in the second (this is Nokogiri's sanity check).

这些错误消息在我看来是相当明确的:您在第一个实例中使用了一个老ruby(并运行Rubygems行为(而不是Nokogiri行为))，并试图在第二个(这是Nokogiri的完整性检查)中链接到libxml2的一个旧版本(known-buggy)版本。

If you want to "fix" it, make sure you're using the right Ruby version, and either install an acceptable libxml2 or let Nokogiri use its vendored versions for you.

如果您想要“修复”它，请确保您使用的是正确的Ruby版本，或者安装一个可接受的libxml2，或者让Nokogiri为您使用它的版本。

After working with someone who is more familiar with CentOS, I discovered that the issue was being caused by not having cmake installed as well as trying to install a gem through sudo.

在和一个更熟悉CentOS的人合作之后，我发现这个问题是由于没有安装cmake，并试图通过sudo安装gem。

Tip: When installing gems always use the root user.

提示:在安装gems时，总是使用根用户。
