python - python 3.7 上的 rpy2 3.2.0 存在导入 robjects 问题

Question

python 3.7.3，rpy2 3.2.0，代码如下:

从 rpy2 导入 robjects

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File ".virtualenvs/flask3/lib/python3.7/site-packages/rpy2/robjects/__init__.py", line 14, in <module>
    import rpy2.rinterface as rinterface
  File ".virtualenvs/flask3/lib/python3.7/site-packages/rpy2/rinterface.py", line 6, in <module>
    from rpy2.rinterface_lib import openrlib
  File ".virtualenvs/flask3/lib/python3.7/site-packages/rpy2/rinterface_lib/openrlib.py", line 65, in <module>
    _get_dataptr_fallback)
  File ".virtualenvs/flask3/lib/python3.7/site-packages/rpy2/rinterface_lib/openrlib.py", line 50, in _get_symbol_or_fallback
    res = getattr(rlib, symbol)
RuntimeError: found a situation in which we try to build a type recursively.  This is known to occur e.g. in ``struct s { void(*callable)(struct s); }''.  Please report if you get this error and really need support for your case.

发生什么事了？这看起来像是 rypy2 的标准过程，实际上也是我们在 python 2 下使用它的方式。

同样的问题适用于任何类型的 rpy2 导入:import rpy2.robjects.tests 等。

我遇到了同样的问题，并发现了上面链接的@ejolly 相同的问题。为了解决这个问题，我将 cffi 库从 1.13.0 降级到 1.12.3。

pip install cffi==1.12.3

效果非常好。
