Question

我正在尝试在r中安装“XML”包，但是会发生错误请告诉我出了什么问题。

操作系统：OS X 10.11.6
R版本：3.3.2
执行“install.packages（”XML“）时的错误消息如下。

* installing *source* package ‘XML’ ...

我设置LIBXML_INCDIR = / usr / local / Cellar / libxml2 / 2.9.4，然后重试。
然后发生另一个错误。

You specified LIBXML_INCDIR, but we couldn't find parser.h
Please specify it correctly and re-run the INSTALL'ation.
ERROR: configuration failed for package ‘XML’

还尝试使用LIBXML_INCDIR = / usr / local / Cellar / libxml2 / 2.9.4 / include
结果与上述相同。

此致

Answer 1

这在Mac OS X 10.11中适用于我：

在终端：

type xml2-config
xml2-config is /opt/local/bin/xml2-config

在R：

Sys.setenv(XML_CONFIG="/opt/local/bin/xml2-config")

Answer 2

您可以编辑文件beer以包含：

，而不是强制链接libxml2版本与自制程序。

$HOME/.R/Makevars

编辑SDK版本（例如上例中的MacOSX10.13）以匹配您安装的版本。有关（最小）解释，请参阅https://forums.developer.apple.com/thread/87829。

Answer 3

对于Homebrew的libxml2安装，我使用了：

export XML_CONFIG=/usr/local/Cellar//libxml2/2.9.10_1/bin/xml2-config

它奏效了。
