在Linux系统中，您可以创建从“life”文件夹到nib.py文件的软链接。然后，你可以像这样简单地导入它:

import nib

这是对我来说最简单的解决方法:

from ptdraft import nib

二线最简解

import os, sys
sys.path.insert(0, os.getcwd()) 

如果父目录是你的工作目录，你想从子脚本调用另一个子模块。

您可以在任何脚本中从父目录导入所有子模块并执行

python child_module1/child_script.py

你可以在“模块搜索路径”中使用OS依赖路径。路径。 因此，您可以轻松地添加如下父目录

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

如果要添加父-父目录，

sys.path.insert(0,'../..')

这在python2和python3中都适用。

如果将模块文件夹添加到PYTHONPATH中失败，则可以修改sys. conf文件。Python解释器在你的程序中搜索要导入的模块的路径列表，Python文档说:

When a module named spam is imported, the interpreter first searches for a built-in module with that name. If not found, it then searches for a file named spam.py in a list of directories given by the variable sys.path. sys.path is initialized from these locations: the directory containing the input script (or the current directory). PYTHONPATH (a list of directory names, with the same syntax as the shell variable PATH). the installation-dependent default. After initialization, Python programs can modify sys.path. The directory containing the script being run is placed at the beginning of the search path, ahead of the standard library path. This means that scripts in that directory will be loaded instead of modules of the same name in the library directory. This is an error unless the replacement is intended.

知道了这一点，你可以在程序中执行以下操作:

import sys
# Add the ptdraft folder path to the sys.path list
sys.path.append('/path/to/ptdraft/')

# Now you can import your module
from ptdraft import nib
# Or just
import ptdraft

导入系统 sys.path.append(“. . /”)
