Question

在设置我的活跃商家git时，我一直在努力解决安装libxml-ruby的错误。我多次用Google搜索错误的所有组成部分，但我只是不确定我在看什么。有一堆“不” - 有人知道如何解释我可能缺少的东西吗？

检查/ opt / include / libxml2中的libxml / xmlversion.h，/ usr / local / include / libxml2，/ usr / include / libxml2 ...否

告诉我你可能遗漏了libxml2

尝试安装它：

sudo apt-get install libxml2-dev

好吧，正如@TommyNicholas所要求的那样，我将尝试解释为什么我放大了libxml2所有其他人 - 这有点像直觉，但我有一些线索：

这是安装声明失败之前的最后一行，因此该行很有可能成为一个严重错误（安装在其他失败之后继续......）它可能不是唯一的一个，但它值得注意。
错误消息显示它在libxml2，/opt/include/和/usr/local/include/下搜索了usr/include/ - 并且没有找到它，因此可以说它不是安装。
在installing Nokogiri时会发生类似的错误，因此尝试相同的解决方案并没有什么坏处。
无论如何，如果所有其他方法都失败了 - RTFM - 虽然我的猜测有效，但下一步是阅读错误消息，提示日志中可能有更完整的报告 - mkmg.log：

检查mkmf.log文件以获取更多详细信息。

错误Rails - libxml-Ruby
