xml安装版本:
2_1.2.0
安装xml2包报错如下:
During startup - Warning messages:
1: Setting LC_TIME failed, using "C"
2: Setting LC_MESSAGES failed, using "C"
3: Setting LC_MONETARY failed, using "C"
* installing *source* package ‘xml2’ ...
** package ‘xml2’ successfully unpacked and MD5 sums checked
Found pkg-config cflags and libs!
Using PKG_CFLAGS=-I/usr/include/libxml2
Using PKG_LIBS=-L/usr/lib -lxml2 -lz -lpthread -licucore -lm
------------------------- ANTICONF ERROR ---------------------------
Configuration failed because libxml-2.0 was not found. Try installing:
* deb: libxml2-dev (Debian, Ubuntu, etc)
* rpm: libxml2-devel (Fedora, CentOS, RHEL)
* csw: libxml2_dev (Solaris)
If libxml-2.0 is already installed, check that 'pkg-config' is in your
PATH and PKG_CONFIG_PATH contains a libxml-2.0.pc file. If pkg-config
is unavailable you can set INCLUDE_DIR and LIB_DIR manually via:
R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'
--------------------------------------------------------------------
ERROR: configuration failed for package ‘xml2’
* removing ‘/usr/local/lib/R/3.5/site-library/xml2’
The downloaded source packages are in
‘/private/tmp/Rtmp9tYdXH/downloaded_packages’
Warning message:
In install.packages("xml2") :
installation of package ‘xml2’ had non-zero exit status
在网上调研了半天得到的导致结论是pkg-config不能准确定位到libxml2的位置, 这样说不是很准确, 但不纠结, 下边我们来看如何解决.
解决办法
brew安装如下包
brew install pkg-config
brew install libxml2
注意, libxml2 需配置一下PATH
brew info libxml2
# ==============================================================
==> Caveats
libxml2 is keg-only, which means it was not symlinked into /usr/local,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.
If you need to have libxml2 first in your PATH run:
echo 'export PATH="/usr/local/opt/libxml2/bin:$PATH"' >> ~/.zshrc
For compilers to find libxml2 you may need to set:
export LDFLAGS="-L/usr/local/opt/libxml2/lib"
export CPPFLAGS="-I/usr/local/opt/libxml2/include"
For pkg-config to find libxml2 you may need to set:
export PKG_CONFIG_PATH="/usr/local/opt/libxml2/lib/pkgconfig"
下载xml2包, 解压
地址: https://mirrors.tongji.edu.cn/CRAN/src/contrib/xml2_1.2.0.tar.gz, 如果地址失效, 在R安装这个包 - install.packages('xml2'), 就可以看到可用地址了
解压之后在iterm2(终端)打开:
➜ ~ cd Downloads/xml2
➜ xml2 pwd

➜ xml2 ll

注意, 其中configure文件需要我们修改
修改configure文件
将
xml2-config --version >/dev/null 2>&1
if [ $? -eq 0 ]; then
PKGCONFIG_CFLAGS=`xml2-config --cflags`
PKGCONFIG_LIBS=`xml2-config --libs`
# MacOS versions El Capitan and later ship a xml2-config which appends `xcrun
# --show-sdk-path` to the xml2-config. So we remove it if it is present.
# (https://stat.ethz.ch/pipermail/r-sig-mac/2016-September/012046.html)
if echo $OSTYPE | grep -q '^darwin'; then
PKGCONFIG_CFLAGS=`echo $PKGCONFIG_CFLAGS | perl -pe "s{\Q\`xcrun -show-sdk-path\`\E}{}"`
PKGCONFIG_LIBS=`echo $PKGCONFIG_LIBS | perl -pe "s{\Q\`xcrun -show-sdk-path\`\E}{}"`
fi
else
pkg-config --version >/dev/null 2>&1
if [ $? -eq 0 ]; then
PKGCONFIG_CFLAGS=`pkg-config --cflags $PKG_CONFIG_NAME`
PKGCONFIG_LIBS=`pkg-config --libs $PKG_CONFIG_NAME`
fi
fi
修改为
if [ $(command -v pkg-config) ]; then
PKGCONFIG_CFLAGS=$(pkg-config --cflags $PKG_CONFIG_NAME)
PKGCONFIG_LIBS=$(pkg-config --libs $PKG_CONFIG_NAME)
fi
或者
# 添加制定路径 - libxml2 文件夹的路径
PKG_CFLAGS='-I/usr/local/Cellar/libxml2/2.9.9_2/include/libxml2'
PKG_LIBS='-L/usr/local/Cellar/libxml2/2.9.9_2/lib -lxml2'

iterm2安装xml2
