R-3.2.1无法加载共享对象internet.so。

Question

我在将R版本从3.1.3升级到3.2.1后，无法从CRAN安装软件包。

错误信息为共享对象internet.so无法加载。

以下帖子似乎涉及类似问题。 Error in install.packages: internet routines cannot be loaded using StatET while it works in R console

你是如何安装R的？通过官方软件包仓库吗？看起来你安装的R版本与安装的curl版本不兼容。更具体地说，R需要一个名为curl_multi_wait的curl函数，该函数似乎是在2013年左右引入curl中的。你的curl版本可能比那个更旧。 - mdd

curl/libcurl的最低版本应为7.28.0，根据文档。您安装了哪个版本？ - mdd

我之前安装了curl 7.35版本。 我更新到了7.43版本，并重新安装了R-3.2.1。 但是我仍然得到完全相同的错误版本。 R-3.2.1是从CRAN下载的。 我是从源代码包中安装的。 wget http://cran.utstat.utoronto.ca/src/base/R-3/R-3.2.1.tar.gz - Alex

wget http://cran.utstat.utoronto.ca/src/base/R-3/R-3.2.1.tar.gz tar xzvf R-3.2.1.tar.gz;mv R-3.2.1 build; mkdir R-3.2.1 configure --prefix=/software/areas/ircm/tools/R-3.2.1;make;make install - Alex

[blancha@lg-1r17-n03 build]$ curl --version curl 7.43.0 (x86_64-unknown-linux-gnu) libcurl/7.43.0 OpenSSL/1.0.1e zlib/1.2.3 libidn/1.18 - Alex

Answer 1

修复了！感谢@David Robinson的建议，让我找到了正确的解决方法。

我只需在我的.bash_profile中添加以下命令即可解决问题：

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