Ubuntu 14.04 配置：错误：“libxml 未找到”

Sky*_*ker 4 xml r xml-libxml ubuntu-14.04

尝试按如下方式安装 XML 包时出现错误configure: error: "libxml not found"。看来 R 正在从 Anaconda 获取 libxml2 安装。我怎样才能解决这个问题？

我也明白这个：

\n\n

$ type xml2-config\nxml2-config is /opt/dev/anaconda/2018.12/bin/xml2-config\n

但在 R 环境中设置配置没有帮助：

\n\n

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

更新我已经在系统中安装了 libxml2 请参阅：
