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
3
4
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:
