我就废话不多说了,大家往下看吧~
P
|-A
| a.py
|-B
| b.py
文件结构如上,在windows下
a想运行b中的方法,可以直接写成
1
2
|
from B impot b b.fun() |
但是在linux中会出现
ModuleNotFoundError: No module named 'B'
可以通过引入sys添加路径解决
1
2
3
|
import sys sys.path.append( "/P/B" ) from B impot b |
在程序中为了也有良好的移植性,可以在代码中显式添加路径,
比如用os的方法:
1
|
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) |
或者pathlib 方法:
1
|
BASE_DIR = Path(__file__).resolve().parent.parent |
最后可以添加到 sys.path中
1
|
sys.path.append( str (BASE_DIR)) |
补充:python import导入三种方式(导入不同文件夹的文件,window和linux的区别)
import导入方式
1、导入python自有的库
1
|
import json |
2、导入同级目录下的文件,比如在logindev.py导入read_config.py文件
1
2

5
|
# coding = utf-8 from read_config import ReadConfig import requests import json # 拼接请求参数,获取cookie,作为后续登录使用 |
3、导入不同级别目录下的文件:
a、windows环境

# coding = utf-8 import datetime import allure import pytest import json import sys """windows执行的时候,直接在系统路径上新增文件夹路径""" sys.path.append( "../common" ) """linux执行的时候,直接按照相对路径引用即可""" from common import http_request |
这段代码在linux下报如下错误:

以上为个人经验,希望能给大家一个参考,也希望大家多多支持服务器之家。如有错误或未考虑完全的地方,望不吝赐教。
