Playwright运行报错：ModuleNotFoundError: No module named 'pyee.asyncio'

问题背景 #

在WSL2的Ubuntu18.04环境下运行Playwright异步代码时，出现模块找不到的错误，具体报错为ModuleNotFoundError: No module named 'pyee.asyncio'。

环境配置 #

ubuntu18.04(wsl2)
playwright 1.29.1
pyee 8.22
scrapy-playwright 0.024

运行代码 #

import asyncio
from playwright.async_api import async_playwright
import time

async def main():
    async with async_playwright() as p:
        browser = await p.chromium.launch_persistent_context(headless=False, user_data_dir='', args=['--disable-infobars'])
        page = await browser.new_page()
        await page.goto('https://www.baidu.com')
        time.sleep(100)
        await page.close()

asyncio.run(main())

报错回溯 #

    from pyee.asyncio import AsyncIOEventEmitter
ModuleNotFoundError: No module named 'pyee.asyncio'

问题原因 #

你安装的pyee 8.22版本与playwright 1.29.1不兼容。pyee从8.x版本开始调整了异步模块的导入路径，将AsyncIOEventEmitter从pyee.asyncio迁移到了pyee.asyncio.asyncio，而旧版本的Playwright仍然使用旧的导入路径，导致找不到模块。

解决方案 #

1. 降级pyee到兼容版本 #

执行以下命令降级pyee到7.x版本（与playwright 1.29.1兼容）：

pip install pyee==7.0.4 --force-reinstall

或者指定版本范围：

pip install "pyee<8" --force-reinstall

2. 验证安装 #

安装完成后，在Python环境中验证导入是否正常：

from pyee.asyncio import AsyncIOEventEmitter

如果没有报错，说明版本兼容。

3. 重新运行代码 #

再次执行你的Playwright代码，应该可以正常启动浏览器并访问页面。
