Where is Python's sys.path initialized from? UPD : Python is adding some paths before refering to PYTHONPATH: >>> import sys >>> from pprint import pprint as p >>> p(sys.path) ['', 'C:\Python25\lib\site-packages\setuptools-0.6c9-py2.5.egg', 'C:\Python25\lib\site-packages\orbited-0.7.8-py2.5.egg', 'C:\Python25\lib\site-packages\morbi
Python的sys.path从哪里初始化？ UPD ：Python在引用PYTHONPATH之前添加了一些路径： >>> import sys >>> from pprint import pprint as p >>> p(sys.path) ['', 'C:\Python25\lib\site-packages\setuptools-0.6c9-py2.5.egg', 'C:\Python25\lib\site-packages\orbited-0.7.8-py2.5.egg', 'C:\Python25\lib\site-packages\morbid-0.8.6.1-py2.5.egg', 'C:\Pyt

I'm having trouble importing a python module using rubypython. I know that the library paths are different which I think is the issue. For example running: require "rubypython" require 'pry' RubyPython.start # start the Python interpreter py = RubyPython sys = py.import 'sys' p sys.version p sys.path.inspect RubyPython.stop # stop the Python interpreter gives: '2.7.2 (default, Oct 11
我无法使用rubypython导入python模块。 我知道图书馆的路径是不同的，我认为这是问题。 例如运行： require "rubypython" require 'pry' RubyPython.start # start the Python interpreter py = RubyPython sys = py.import 'sys' p sys.version p sys.path.inspect RubyPython.stop # stop the Python interpreter 得到： '2.7.2 (default, Oct 11 2012, 20:14:37) n[GCC 4.2.1 Compatible Apple Clang 4.0 (tags/Apple

使用pool.map(funct, iterable)时出现此错误： AttributeError: __exit__ 没有说明，只将堆栈跟踪模块内的pool.py文件。 以这种方式使用： with Pool(processes=2) as pool: pool.map(myFunction, mylist) pool.map(myfunction2, mylist2) 我怀疑可能会有一个问题与可picklability（python需要pickle ，或将列表数据转换为字节流），但我不知道这是否属实或如何调试。 编辑：产生此错误的新代码格式： def governi
