Playwright跨文件导入代码报错：module 'playwright' has no attribute 'chromium'

错误信息 #

Job "runF5 (trigger: interval[1 day, 0:00:00], next run at: 2023-01-31 00:24:00 PKT)" raised an exception

AttributeError: module 'playwright' has no attribute 'chromium'

问题原因 #

文件2中直接传递了playwright模块对象给m5.runF5()，但文件1的runF5函数需要的是**Playwright类的实例**，而非模块本身。chromium是Playwright实例的属性，模块级别的playwright并没有这个属性，因此触发报错。

解决方案 #

方案1：在文件2中正确获取Playwright实例传递 #

修改文件2代码，通过sync_playwright()获取Playwright实例后再传递：

from playwright.sync_api import sync_playwright
import m5
from apscheduler.schedulers.background import BackgroundScheduler

def runF5():
    with sync_playwright() as playwright:
        m5.runF5(playwright)

scheduler = BackgroundScheduler()
scheduler.add_job(runF5, 'interval', days=1, start_date='2022-01-01 03:31:00', timezone='Asia/Karachi')
scheduler.start()

while True:
    pass

方案2：让文件1的函数自行处理Playwright实例（更简洁） #

修改文件1的runF5函数，内部直接启动Playwright，无需外部传参：

from playwright.sync_api import sync_playwright, expect
import random
import time
import sys
import pyautogui

def runF5() -> None:
    with sync_playwright() as playwright:
        browser = playwright.chromium.launch(headless=False, slow_mo=600)
        context = browser.new_context()
        page = browser.new_page()
        page.goto('https://www.google.com/', timeout=0)
        # 后续操作完成后可主动关闭浏览器
        browser.close()

对应文件2代码简化为：

import m5
from apscheduler.schedulers.background import BackgroundScheduler

def runF5():
    m5.runF5()

scheduler = BackgroundScheduler()
scheduler.add_job(runF5, 'interval', days=1, start_date='2022-01-01 03:31:00', timezone='Asia/Karachi')
scheduler.start()

while True:
    pass

关键说明 #

• sync_playwright()是Playwright提供的同步API入口，上下文管理器会自动处理Playwright的启动与关闭。
• 确保已安装对应浏览器驱动，可执行命令 playwright install chromium 完成安装。
