R-3.2.1無法加載共享對象internet.so

將R從3.1.3升級到3.2.1後，我無法安裝來自CRAN的軟件包。錯誤消息是無法加載共享對象internet.so。R-3.2.1無法加載共享對象internet.so

你怎麼安裝R？通過官方軟件倉庫？看來你安裝的R版本與curl的安裝版本不兼容。更具體地說，R需要一個curl函數'''''curl_multi_wait'''，這似乎是在2013年左右的curl中引入的。你的curl版本可能比這個更早。 – mdiener

根據[documentation]（http://curl.haxx.se/libcurl/c/curl_multi_wait.html），curl/libcurl的最低版本應爲7.28.0。你安裝了哪個版本？ – mdiener

我已經安裝了curl 7.35版本。我已更新至7.43，並重新安裝了R-3.2.1。我仍然得到完全相同的錯誤版本。 R-3.2.1是從CRAN下載的。我是從源碼包安裝的。 wget http://cran.utstat.utoronto.ca/src/base/R-3/R-3.2.1.tar.gz – Alex

固定！謝謝@David Robinson的建議。他們讓我走上正軌。

我剛添加下面的命令來我.bash_profile，問題得到了解決：

export LD_LIBRARY_PATH=$TOOLS/curl-7.43.0/lib:$LD_LIBRARY_PATH
