我在环境中使用64Python 3.3.1位在Ubuntu 13.0464 位下运行的Eclipse 4.364 位。我的项目位于以下目录结构中。Pydev 2.7.6virtualenv

Dictionary
     |
     ----------------------------
     |                          |
     src                        test
       |                          |
       petaapan                   petaapan
          |   |                   |      |
__init__.py logging        __init__.py  logging
            |     |                     |     |
   __init__.py    mplogging.py  __init__.py  test_mplogging.py

当我尝试test_mplogging.py使用pytest作为测试运行器运行时，我得到以下结果：

pydev debugger: starting
============================= test session starts ==============================
platform linux -- Python 3.3.1 -- pytest-2.3.5

E   ImportError: No module named 'petaapan.logging.mplogging'

我sys.path已经Dictionary/test提前了，Dictionary/src所以首先搜索测试树，看起来这就是常规包导入失败的原因。

我的下一次尝试是使用命名空间包做同样的事情，所以我删除了所有__init__.py文件并得到以下结果：

以下是test_mplogging.py相关部分：

import logging
from os import getcwd

from multiprocessing import Queue, Process
import petaapan.logging.mplogging as ml

谁能建议我在这种情况下需要做什么？

正如我所看到的，你有petaapan.logging.mploggingunder Dictionary/src，但没有 under Dictionary/test。

petaapan我相信解释器会从import指令中解析并找到它Dictionary/test，然后建议它是您引用的模块。但之后它无法找到（mplogging在Dictionary/test/petaapan/logging检测到的模块范围内），因此引发异常。
