在python 2.6上安装rpy2

我需要在运行Python2.6旧版CentOS的机器上从源代码安装包rpy2。rpy2的当前版本是2.5，并且它仅在python>=2.7上兼容

从中，我检查了最后几个版本，发现2.2是最后一个在Python2.6上运行的版本。很遗憾，它无法安装：

# python26 setup.py build install
running build
running build_py
running build_ext
Traceback (most recent call last):
  File "setup.py", line 441, in <module>
    [os.path.join('doc', 'source', 'rpy2_logo.png')])],
  File "/usr/lib64/python2.6/distutils/core.py", line 152, in setup
    dist.run_commands()
  File "/usr/lib64/python2.6/distutils/dist.py", line 975, in run_commands
    self.run_command(cmd)
  File "/usr/lib64/python2.6/distutils/dist.py", line 995, in run_command
    cmd_obj.run()
  File "/usr/lib64/python2.6/distutils/command/build.py", line 134, in run
    self.run_command(cmd_name)
  File "/usr/lib64/python2.6/distutils/cmd.py", line 333, in run_command
    self.distribution.run_command(command)
  File "/usr/lib64/python2.6/distutils/dist.py", line 994, in run_command
    cmd_obj.ensure_finalized()
  File "/usr/lib64/python2.6/distutils/cmd.py", line 117, in ensure_finalized
    self.finalize_options()
  File "setup.py", line 152, in finalize_options
    config += get_rconfig(r_home, about)
  File "setup.py", line 312, in get_rconfig
    rc = RConfig.from_string(rconfig, allow_empty = allow_empty)
  File "setup.py", line 272, in from_string
    + '\nin string\n' + string)
ValueError: Invalid substring

我需要安装以前版本的R 2.12或2.13，如

中所述要使用较旧的rpy2，您可能还必须使用同样旧的R版本。作为替代方案，应该考虑从源代码编译最新的Python…是的，这就是问题所在！我安装了与rpy 2.2兼容的R版本，如我提供的链接中所述，并且一切正常。
