I was trying to use a R package called "XML", 但遇到了麻煩,安裝後使用它:如何指定安裝R包時使用哪個R lib?
# in R environment
> library("XML")
> XML::parseURI("")
Error in XML::parseURI("") : cannot parse URI
問題竟然是R找不到安裝在我的目錄「的libxml2」的最新版本:
echo $LD_LIBRARY_PATH /somewhere/Jun/Programme/libxml2-devel-2.9.1-2.1/usr/lib/:
檢索有關libxml2的「XML」的版本信息鏈接到
> path = unclass(getLoadedDLLs()[["XML"]])$path
> path
[1] "/misc/home/Jun/Programme/R-3.3.1/lib64/R/library/XML/libs/XML.so"
> system2("ldd",args=path)
linux-vdso.so.1 => (0x00007fff2a9e8000)
libxml2.so.2 => /usr/lib64/libxml2.so.2 (0x00002aefc088a000) # XML is using a common "libxml2.so.2" not the one I installed.
libz.so.1 => //home/Jun/Programme/zlib-1.2.11/lib/libz.so.1 (0x00002aefc0bc8000)
libm.so.6 => /lib64/libm.so.6 (0x00002aefc0de5000)
libdl.so.2 => /lib64/libdl.so.2 (0x00002aefc1068000)
...
任何建議這樣做?
爲了使 「XML」 鏈接到安裝在我的目錄中的libxml2, 我做出這樣的努力:爲libxml2的

什麼'/somewhere/Jun/Programme/libxml2-devel-2.9.1-2.1/usr/bin/xml2-config --cflags --libs'的輸出? – nwellnhof
@nwellnhof,hi nwellnhof,你可能會懷疑,'xml2-config --cflags -I/usr/include/libxml2 xml2-config --libs -lxml2 -lz -lm -ldl#xml2-config points在系統庫。 '我的xml2-config沒有指向我安裝的lib。我通過編譯而不是使用「rpm」來重新安裝來解決我的問題。感謝您的關注和建議。 – Jun
