python从同一文件夹导入失败

python从同一文件夹导入失败,python,import,importerror,Python,Import,Importerror,我的目录结构如下: |- project |- commands.py |- Modules | |- __init__.py | |- base.py | \- build.py \- etc.... 我在\uuuu init\uuuuuuy.py commands = [] hooks = [] def load_modules(): """ dynamically loads commands from the /modules subdirectory

我的目录结构如下:

|- project
  |- commands.py
  |- Modules
  | |- __init__.py
  | |- base.py
  | \- build.py
  \- etc....
我在
\uuuu init\uuuuuuy.py

commands = []
hooks = []

def load_modules():
    """ dynamically loads commands from the /modules subdirectory """
    path = "\\".join(os.path.abspath(__file__).split("\\")[:-1])
    modules = [f for f in os.listdir(path) if f.endswith(".py") and f != "__init__.py"]
    print modules
    for file in modules:
        try:
            module = __import__(file.split(".")[0])
            print module
            for obj_name in dir(module):
                try:
                    potential_class = getattr(module, obj_name)
                    if isinstance(potential_class, Command):
                        #init command instance and place in list
                        commands.append(potential_class(serverprops))
                    if isinstance(potential_class, Hook):
                        hooks.append(potential_class(serverprops))
                except:
                    pass
        except ImportError as e:
            print "!! Could not load %s: %s" % (file, e)
    print commands
    print hooks

我试图让
\uu init\uuuuuuuuuuuuuuuuuuuuuuuuupy
将适当的命令和钩子加载到给定的列表中,但是我总是在
模块=\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu(file.split(.“”[0])
处遇到导入错误,即使
和base.py等都在同一个文件夹中。我已经验证过,任何模块文件中的任何内容都不需要
\uuu init\uuuu.py
中的任何内容,因此我真的不知道该怎么做。

您所缺少的只是在系统路径上有模块。加

import sys
sys.path.append(path)
路径=…
行之后,应该设置。以下是我的测试脚本:

import os, os.path, sys

print '\n'.join(sys.path) + '\n' * 3

commands = []
hooks = []

def load_modules():
    """ dynamically loads commands from the /modules subdirectory """
    path = os.path.dirname(os.path.abspath(__file__))

    print "In path:", path in sys.path
    sys.path.append(path)

    modules = [f for f in os.listdir(path) if f.endswith(".py") and f != "__init__.py"]
    print modules
    for file in modules:
        try:
            modname = file.split(".")[0]
            module = __import__(modname)
            for obj_name in dir(module):
                print '%s.%s' % (modname, obj_name )
        except ImportError as e:
            print "!! Could not load %s: %s" % (file, e)
    print commands


load_modules()

\uuuuu导入\uuuuu
有许多需要注意的细节,尤其是与
fromlist
有关的细节。试着搜索一下,看看你是否能找到答案。
path=os.path.dirname(os.path.abspath(_文件__))
(更正确,顺便说一下跨平台)从何处以及如何调用
load_modules()
?在初始化期间从commands.py调用load_modules
