我就廢話不多說了，大家往下看吧~

P|-A| a.py|-B| b.py

a想運(yùn)行b中的方法，可以直接寫成

from B impot bb.fun()但是在linux中會(huì)出現(xiàn)

ModuleNotFoundError: No module named ’B’

可以通過引入sys添加路徑解決

import syssys.path.append('/P/B')from B impot b

在程序中為了也有良好的移植性，可以在代碼中顯式添加路徑，

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))或者pathlib 方法：

BASE_DIR = Path(__file__).resolve().parent.parent

最后可以添加到 sys.path中

sys.path.append(str(BASE_DIR))

補(bǔ)充：python import導(dǎo)入三種方式（導(dǎo)入不同文件夾的文件，window和linux的區(qū)別）

import導(dǎo)入方式

import json2、導(dǎo)入同級目錄下的文件，比如在logindev.py導(dǎo)入read_config.py文件

# coding = utf-8from read_config import ReadConfigimport requestsimport json# 拼接請求參數(shù)，獲取cookie，作為后續(xù)登錄使用3、導(dǎo)入不同級別目錄下的文件：a、windows環(huán)境

# coding = utf-8import datetimeimport allureimport pytestimport jsonimport sys'''windows執(zhí)行的時(shí)候，直接在系統(tǒng)路徑上新增文件夾路徑'''sys.path.append('../common')'''linux執(zhí)行的時(shí)候，直接按照相對路徑引用即可'''from common import http_request

這段代碼在linux下報(bào)如下錯(cuò)誤：

==================================== ERRORS ====================================_______________ ERROR collecting test_case/test_member_ticket.py _______________ImportError while importing test module ’/var/jenkins_home/workspace/pytest_allure/test_case/test_member_ticket.py’.Hint: make sure your test modules/packages have valid Python names.Traceback:test_member_ticket.py:8: in <module> from common import http_requestE ImportError: No module named ’common’b、linux環(huán)境

以上為個(gè)人經(jīng)驗(yàn)，希望能給大家一個(gè)參考，也希望大家多多支持好吧啦網(wǎng)。如有錯(cuò)誤或未考慮完全的地方，望不吝賜教。
