pyppeteer.errors.BrowserError：浏览器意外关闭

Question

今天，我学习了名为 pyppeteer 的库，当我运行我的代码时

import asyncio
from pyppeteer import launch


async def main():
    browser = await launch(options={'devtools': True, 'headless': False})
    page = await browser.newPage()
    await page.goto('http://example.com')
    await page.screenshot({'path': 'baidu.png'})
    await browser.close()


asyncio.get_event_loop().run_until_complete(main())

我有：

pyppeteer.errors.BrowserError: Browser closed unexpectedly:

Answer 1

这是因为pyppeteer不会安装所需的依赖项chromium。所以你应该自己安装它们。

执行ldd ~/.local/share/pyppeteer/local-chromium/588429/chrome-linux/chrome | grep 'not found'以获取丢失的依赖项：

输出示例：

libXcursor.so.1 => not found
libnss3.so => not found
libnssutil3.so => not found
libsmime3.so => not found
libcups.so.2 => not found
libXss.so.1 => not found
libpangocairo-1.0.so.0 => not found
libpango-1.0.so.0 => not found
libcairo.so.2 => not found
libatk-1.0.so.0 => not found
libatk-bridge-2.0.so.0 => not found
libgtk-3.so.0 => not found
libgdk-3.so.0 => not found
libgdk_pixbuf-2.0.so.0 => not found

你可以一一安装它们，或者安装google-chrome它的依赖项。

对于 ubuntu/debian：

libXcursor.so.1 => not found
libnss3.so => not found
libnssutil3.so => not found
libsmime3.so => not found
libcups.so.2 => not found
libXss.so.1 => not found
libpangocairo-1.0.so.0 => not found
libpango-1.0.so.0 => not found
libcairo.so.2 => not found
libatk-1.0.so.0 => not found
libatk-bridge-2.0.so.0 => not found
libgtk-3.so.0 => not found
libgdk-3.so.0 => not found
libgdk_pixbuf-2.0.so.0 => not found

再次执行ldd ~/.local/share/pyppeteer/local-chromium/588429/chrome-linux/chrome | grep 'not found'，可能会漏掉一些依赖：

libXss.so.1 => not found

然后执行apt install libxss1安装遗漏的libXss.so.1

额外的

如果你想截图，也许你需要一些中日韩字体：

sudo apt install fonts-wqy-zenhei

我得到了同样的结果，当我尝试从终端启动 chromium 时，我注意到它需要在没有沙箱参数的情况下运行，所以只需添加它，您的代码就可以工作：

browser=await launch(options={'args': ['--no-sandbox']})

Answer 3

对我来说，我在 docker 中运行，结果是铬没有正确安装所需的库：https : //techoverflow.net/2018/06/05/how-to-fix-puppetteer-error-while-加载共享库-libx11-xcb-so-1-cannot-open-shared-object-file-no-such-file-or-directory/
