python - Ruby 2.1.5和RubyPython 0.6.3- RubyPython::InvalidInterpreter:指定了无效的解释器

我正在尝试在Debian 8上使用RubyPython，但一直无法使用。 RubyPython.start总是引发InvalidInterpreter异常。我试过指定python解释器可执行文件，但这没关系。下面的片段显示了我的版本，并尝试从撬动中启动

rubypython (0.6.3)
adrew@bunny:~$ ruby --version
ruby 2.1.5p273 (2014-11-13) [x86_64-linux-gnu]
adrew@bunny:~$ python --version
Python 2.7.9
adrew@bunny:~$ which python2.7
/usr/bin/python2.7
adrew@bunny:~$ pry
[1] pry(main)> require 'rubypython'
=> true
[2] pry(main)> RubyPython.start
RubyPython::InvalidInterpreter: An invalid interpreter was specified.
from /var/lib/gems/2.1.0/gems/rubypython-0.6.3/lib/rubypython.rb:67:in `block in start'
[3] pry(main)> RubyPython.start(:python_exe => "/usr/bin/python2.7")
RubyPython::InvalidInterpreter: An invalid interpreter was specified.
from /var/lib/gems/2.1.0/gems/rubypython-0.6.3/lib/rubypython.rb:67:in `block in start'

最佳答案

我运行strace -ff -o /tmp/pry.txt pry来查看输入require rubypython和RubyPython.start时会发生什么。有像

stat("/usr/lib/libpython2.7.so", 0x7ffd2bf4cde0) = -1 ENOENT (No such file or directory)

意味着rubypython代码正试图找到python库。缺少的是/usr/lib/x86_64-linux-gnu/libpython2.7.so文件成功的stat。

我修改了文件〜/ .gem / ruby / 2.1.0 / gems / rubypython-0.6.3 / lib / rubypython / interpreter.rb

if ::FFI::Platform::ARCH != 'i386'
   @locations << File.join("/opt/local/lib64", name)
   @locations << File.join("/opt/lib64", name)
   @locations << File.join("/usr/local/lib64", name)
   @locations << File.join("/usr/lib64", name)
   @locations << File.join("/usr/lib/x86_64-linux-gnu", name)

最后一行是我插入的位置。此后，RubyPython.start返回true。
