快速运行时和-p文件

Question

我正试图使用python快速构建一个应用程序。大多数情况下，一切都正常。然而，当我试图运行一个读取.p（pickle）文件的函数时，我会遇到I/O错误。奇怪的是，当我在shell中运行同一个python程序时，它运行得很好。

 adam@adam-System-Product-Name:~/reskin/reskin$ quickly run    
      2, No such file or directory,  newSnapShots.p 
    Traceback (most recent call last):
      File "bin/reskin", line 36, in <module> 
        reskin.main()
      File "/home/adam/reskin/reskin/__init__.py", line 31, in main
        window = ReskinWindow.ReskinWindow()
      File "/home/adam/reskin/reskin_lib/Window.py", line 37, in __new__
        new_object.finish_initializing(builder)
      File "/home/adam/reskin/reskin/ReskinWindow.py", line 36, in finish_initializing
        self.set_app_data(builder) 
      File "/home/adam/reskin/reskin/ReskinWindow.py", line 43, in set_app_data
        viewControler.app_by_name("firstVar")
      File "/home/adam/reskin/reskin/back/viewControler.py", line 29, in app_by_name
        app = applicationGetter.get_app_by_name(name)
      File "/home/adam/reskin/reskin/back/applicationGetter.py", line 8, in get_app_by_name
        for snap in savedSnaps:
    TypeError: 'bool' object is not iterable

打印错误的功能：

def get_saved_snaps():
try:
    with open('data/newSnapShots.p','rb') as snapFile:
        savedSnaps = pickle.load(snapFile)
except IOError as e:
    print "{0}, {1},  newSnapShots.p ".format(e.errno, e.strerror)
    return False
return savedSnaps

文件树和.p位置

.

├── applicationGetter.pyc
├── data
│   └── newSnapShots.p    < file here

快速使用Cpickle有问题吗？我应该使用其他东西吗？提前谢谢。

经过一点研究，发现动态或相对文件路径在执行时遇到问题，同时也在快速执行。所以通过切换

  def get_saved_snaps():
try:
    with open('data/newSnapShots.p','rb') as snapFile:

对于

def get_saved_snaps():
try:
    with open('/absolute_path/quickly_project/data/newSnapShots.p','rb') as snapFile:

问题已经解决。我不知道为什么相对路径会这样。
