我使用Microsoft Visual C 2008 Express版进行了编译,使用的Pyparsing模块是最新版本.请问,有谁知道如何使这项工作？

警告实际上在第4行：警告：pyparsing.pyx：413：8：无法访问的代码.然后我将该行改为：

    def __getattr__( self,name ):
            if True: #name not in self.__slots__:
                if name in self.__tokdict:
                    if name not in self.__accumNames:
                        return self.__tokdict[name][-1][0]
                    else:
                        return ParseResults([ v[0] for v in self.__tokdict[name] ])
                else:
                    return ""
            else:
                return None

然后重新编译它.我注意到的一件事是,即使我发出警告和编辑,它们都成功编译,但是当我尝试使用以下代码进行测试时：

    from pyparsing import Word,alphas
    greet = Word(alphas) + ',' + Word(alphas) + '!'
    greeting = greet.parseString('Hello,World!')
    print greeting

我收到以下错误：

    Traceback (most recent call last):
      File "C:\nwaomachux\build_pyparsing\checkout.py",line 1,in 
        from pyparsing import Word,alphas
      File "pyparsing.pyx",line 3414,in init pyparsing (pyparsing.c:100064)
    AttributeError: 'builtin_function_or_method' object has no attribute 'ANY_VALUE'

我会进一步修改文件并发送给你检查它,但我只有几个小时的Pyparsing,所以我还没有掌握完整的源代码.

我不知道将withAttribute.ANY_VALUE = object()移动到def withAttribute(args,* attrDict)的开头是什么效果：function表示.请问,它有什么问题？谢谢.

myapp\
  myapp\
     __init__.py
  tests\
     test_ecprime.py

而我的前任是

C:\Users\wwerner\programming\myapp\

我有以下测试设置：

import pytest
import sys
import pprint

def test_cool():
    pprint.pprint(sys.path)
    assert False

这会产生以下路径：

['C:\\Users\\wwerner\\programming\\myapp\\tests','C:\\Users\\wwerner\\programming\\envs\\myapp\\Scripts','C:\\Windows\\system32\\python34.zip','C:\\python34\\DLLs','C:\\python34\\lib','C:\\python34','C:\\Users\\wwerner\\programming\\envs\\myapp','C:\\Users\\wwerner\\programming\\envs\\myapp\\lib\\site-packages']

当我尝试导入myapp时,我收到以下错误：

ImportError: No module named 'ecprime'

所以看起来它并没有将当前目录添加到我的路径中.

通过将我的导入行更改为如下所示：

import sys
sys.path.insert(0,'.')
import myapp

然后我可以毫无问题地导入myapp.

为什么运行pytest时我的当前目录没有显示在路径中？是我唯一要插入的解决方法.进入sys.path？ (如果重要,我正在使用Python 3.4)

在比较了我的cookiecutter repo的布局之后,事实证明它比这更简单(也更好).

tests/
    __init__.py
    test_myapp.py

将__init__.py文件简单添加到我的测试目录允许我从我的主目录运行py.test.

Returns the native process identifier for the running process,if available. If no process is currently running,0 is returned.

这是什么意思？

这段代码用来解释我的困惑.我使用的是Python 2.7.9,PyQt 4和Windows 7：

import  sys,os,time
from PyQt4.QtCore import *
from PyQt4.QtGui import *

class testLaunch(QWidget):
    def __init__(self):
        QWidget.__init__(self)
        self.process = QProcess(self)
        self.process.start('calc')
        self.process.waitForStarted(1000)
        print "PID:",int(self.process.pid())

if __name__ == "__main__":
    app = QApplication(sys.argv)
    main = testLaunch()
    main.show()
    sys.exit(app.exec_())

这将按预期启动Windows计算器应用程序.在任务管理器中,它显示以下内容：

这显示我的PID为8304.虽然我的应用程序的print语句显示：

PID: 44353984

这代表了什么？它与任务管理器报告的8304 PID相比如何？

typedef struct _PROCESS_informatION {
  HANDLE hProcess;
  HANDLE hThread;
  DWORD  dwProcessId;
  DWORD  dwThreadId;
} PROCESS_informatION,*LPPROCESS_informatION;

PyQt将为这样的结构返回一个sip.voidptr,这就是为什么当你用int()转换它时你会看到这个奇怪的值.你想要的实际pid是dwProcessId,所以你需要使用像ctypes这样的东西来提取它.

这是一些完全未经测试的代码,可以完成这项工作：

import ctypes

class WinProcInfo(ctypes.Structure):
    _fields_ = [
        ('hProcess',ctypes.wintypes.HANDLE),('hThread',('dwProcessID',ctypes.wintypes.DWORD),('dwThreadID',]
LPWinProcInfo = ctypes.POINTER(WinProcInfo)

lp = ctypes.cast(int(self.process.pid()),LPWinProcInfo)
print(lp.contents.dwProcessID)

http = httplib2.Http(cache='.cache')
response,content = http.request('https://sdb.amazonaws.com/...')

但它没有找到CA(我认为)：

File "C:\python32\lib\site-packages\httplib2\__init__.py",line 1059,in request self.disable_ssl_certificate_validation)
File "C:\python32\lib\site-packages\httplib2\__init__.py",line 772,in __init__ context.load_verify_locations(ca_certs)
IOError: [Errno 2] No such file or directory

我的问题：

>我需要做些什么来配置我的操作系统和环境才能使用它？
>我已经看过很多关于确保在Python 2中为SSL构建套接字库的帖子;这适用于Python 3吗？

谢谢！
