Answer 1

你需要匹配的版本RCurl和XML到您正在使用的R版本。由於您的R版本是當前版本的更多主要版本，因此沒有理由認爲當前版本的XML和Rcurl將匹配。你可以嘗試從他們的存檔版本進行安裝。我會在大約一年半前選擇一個.....或者只是更新你的R安裝。

從@TylerRinker的鏈接中可能有一些有用信息的內核，儘管它是錯誤版本的錯誤操作系統。如果你修改了URL並且看看：http://www.stats.ox.ac.uk/pub/RWin/bin/windows/contrib/2.13/你將能夠找出哪個版本的源代碼包用於在redhat上的R的過期版本。

Answer 2

安裝RCurl時出現過類似的問題。我所需要的軟件包在亞馬遜Linux上稱爲libcurl-devel，根據this post that answered my question，CentOS也是如此。它可以使用命令sudo yum install libcurl-devel進行安裝。如果您使用的是基於Debian的發行版，則該軟件包可能會有不同的名稱，並且將使用apt進行安裝。

您的XML lib問題可能有類似的解決方案。

Answer 3

運行過的CentOS 6.4，我剛剛成功地執行的步驟：

1. 與Linux命令行安裝捲曲devel的和的libxml：

$ sudo yum install curl curl-devel 
$ sudo yum -y install libxml2 libxml2-devel 

在R控制檯上，重新啓動R會話並安裝RCurl和XML程序包：

>> install.packages("RCurl") 
>> install.packages("XML") 

裝入庫：

>> library(RCurl) 
>> library(XML) 

希望這爲你節省一天！
