sys.path.insert无法导入其他python文件

标签: python python-3.x import python-import importerror

标题怎么说。我在路径C:\Users\User\Desktop\all python file\5.0.8中具有以下文件结构:

5.0.8\
   tree one\
      little main.py
      sample_tree1.py
   tree two\
       sample_tree2.py

以下是little main.py中的内容:

import sys
import sample_tree1

sys.path.insert(0, r'C:\Users\User\Desktop\all python file\5.0.8\tree two\sample_tree2.py')

import sample_tree2

我想导入sample_tree2.py,但是一旦运行little main.py就会引发错误:

Traceback (most recent call last):

  File "<ipython-input-1-486a3fafa7f2>", line 1, in <module>
    runfile('C:/Users/User/Desktop/all python file/5.0.8/tree one/little main.py', wdir='C:/Users/User/Desktop/all python file/5.0.8/tree one')

  File "C:\Users\User\Anaconda3\lib\site-packages\spyder_kernels\customize\spydercustomize.py", line 786, in runfile
    execfile(filename, namespace)

  File "C:\Users\User\Anaconda3\lib\site-packages\spyder_kernels\customize\spydercustomize.py", line 110, in execfile
    exec(compile(f.read(), filename, 'exec'), namespace)

  File "C:/Users/User/Desktop/all python file/5.0.8/tree one/little main.py", line 12, in <module>
    import sample_tree2

ModuleNotFoundError: No module named 'sample_tree2'

那怎么了?我遵循了this post's top answer,以便从另一个路径分支导入文件,但是它不起作用。

提前谢谢


编辑:

我正在寻找一种解决方案,

1)不需要更改当前工作目录

2)不需要更改文件名

3)不需要更改python终端内容的配置


EDIT2: 添加了一些文件和文件夹结构的屏幕截图,以及错误消息

path without sample_tree2.py path with sample_tree2.py enter image description here enter image description here enter image description here

sys.path.insert()命令将路径插入系统路径,并且不应包含文件名。

请使用您的结构在下面尝试

小main.py:

import sys
import sample_tree1

sys.path.insert(0, r'/my/absolute/path/5.0.8/treetwo')
print(sys.path)  # view the path and verify your insert

import sample_tree2

print(sample_tree2.tree2_func())

treetwo中的sample_tree2.py

def tree2_func():
    return 'called tree2'

输出:

  

['/ my / absolute / path / 5.0.8 / treetwo','...其他路径']

     

称为tree2
