Question

我在Ubuntu 14.04.2 LTS上遇到了rpy2。我有python版本2.7.6并运行

sudo pip install rpy2

似乎很成功。

Collecting rpy2

Successfully built rpy2
Installing collected packages: rpy2
Successfully installed rpy2-2.6.1

然而，当我尝试测试时

python -m rpy2.tests

结果没有前途：

Traceback (most recent call last):
  File "/usr/lib/python2.7/runpy.py", line 162, in _run_module_as_main
    "__main__", fname, loader, pkg_name)

    from rpy2.rinterface._rinterface import *
ImportError: /usr/local/lib/python2.7/dist-packages/rpy2/rinterface/_rinterface.so: undefined symbol: Rf_allocVector3

我已经搜索了此错误但无法找到任何涉及Rf_allocVector3

的内容

R I＆＃39; m的版本是3.0.2，如果有影响。

非常感谢任何帮助。

对于rpy2-2.6.0来说R版本太旧了，我想。

文档让我们希望R-3.0.x没问题，但我认为事实并非如此：http://rpy.sourceforge.net/rpy2/doc-2.6/html/overview.html#requirements

如何在Ubuntu 14.04.2上使用rpy2 2.6.1克服ImportError
