Question

尝试按如下所示安装XML软件包时，出现错误configure: error: "libxml not found"。似乎R正在从Anaconda获取libxml2安装。我该如何解决？

我也明白了：

$ type xml2-config
xml2-config is /opt/dev/anaconda/2018.12/bin/xml2-config

但是在R环境中设置配置没有帮助：

Sys.setenv(XML_CONFIG="/opt/dev/anaconda/2018.12/bin/xml2-config")

更新，我已经在系统中安装了libxml2，请参见：

Answer 1

确保您的系统已安装libxml-dev或libxml2-dev软件包。即

sudo apt-get install libxml2-dev

我无法确定哪个版本是14.04的正确版本（libxml或libxml2），但是您需要确保已安装-dev版本。

Ubuntu 14.04配置：错误：“找不到libxml”
