Rpy2安装的坑 KOBAS两周安装历程

编译R ./configure --enable-R-shlib=yes --with-tcltk --prefix=/opt/soft/R-3.3.1/ --with-readline=yes
with-readline千万不要选no，影响RPY2 默认为yes

否则报错undefined symbol: rl_basic_word_break_characters

当然首先要安装 yum install readline-devel

Traceback (most recent call last):

如果找不到R_HOME可以修改代码setup.py

r_home = subprocess.check_output((r_bin, "RHOME"),universal_newlines=True)

改为

r_home = /opt/soft/R-3.3.1

再

sudo python setup.py build install
