anaconda R - Rcpp 错误

Question

设置（我正在使用 anaconda 分布式 R）：

g++ (Ubuntu 5.4.0-6ubuntu1~16.04.2) 5.4.0 20160609
R version 3.3.1 (2016-06-21) -- "Bug in Your Hair"
Rcpp -- 0.12.5

小例子：

library(Rcpp)
evalCpp("1+1")

错误：

Error in dyn.load("/tmp/RtmpGI3wKi/sourcecpp_6c2722bad7ef/sourceCpp_1.so") : 
  unable to load shared object '/tmp/RtmpGI3wKi/sourcecpp_6c2722bad7ef/sourceCpp_1.so':
  /tmp/RtmpGI3wKi/sourcecpp_6c2722bad7ef/sourceCpp_1.so: undefined symbol: _ZNKSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEE5c_strEv

我在 anaconda google groups 和 stackoverflow 上的 here 上看到了一个非常相似的错误，但没有任何补救提示。

你必须和那些给你 Anaconda 的好人谈谈。在 Debian 和 Ubuntu 上，一切都“正常工作”——并且可以预期，因为部分开发人员使用该平台：

在我的（其中一个）运行 Ubuntu 16.04 的工作站上：

R> library(Rcpp)
R> evalCpp("1+2")
[1] 3
R> 

在新推出的 Rocker r-base 容器中同上（运行 Debian 测试并通过 apt-get 拉入 Rcpp）：

$ docker run --rm -ti r-base /bin/bash
