What happened? / Describe the bug

I see AttributeError sometimes when I run playwright.

Code snippet to reproduce your bug

from playwright.sync_api import sync_playwright

for i in range(10000):
    print(i)
    with sync_playwright() as p:
        pass

Relevant log output

Traceback (most recent call last):
  File "...\scratches\scratch_1.py", line 4, in <module>
    print(i)
  File "...\venv\lib\site-packages\playwright\sync_api\_context_manager.py", line 71, in __enter__
    playwright = self._playwright
AttributeError: 'PlaywrightContextManager' object has no attribute '_playwright'

sounds like #874 if you ask me

[phoenixor]

i followed the official example

from playwright.sync_api import sync_playwright
with sync_playwright() as p:
    browser = p.chromium.launch()
    page = browser.new_page()
    page.goto("http://playwright.dev")
    print(page.title())
    browser.close()

and i got this bug:

Node.js is only supported on Windows 8.1, Windows Server 2012 R2, or higher.
Setting the NODE_SKIP_PLATFORM_CHECK environment variable to 1 skips this
check, but Node.js might not execute correctly. Any issues encountered on
unsupported platforms will not be fixed.Traceback (most recent call last):

@phoenixor use triple backticks if you wanna have a multi line code block, and can you upvote this issue please.

have you fixed this bug??

Interesting, the reason it failed for you is that node needs windows 8, and you have windows 7, the docs don't mention this as a requirement.

@phoenixor I'm running into this same issue, were you able to fix it/find a workaround?

the problem is not nodejs version i think. i'v tried to reinstall nodejs v11.15.0 and v10.24.1, but i got the same bug

From System Requirements in the official Doc

Playwright requires Node.js version 12 or above. The browser binaries for Chromium, Firefox and WebKit work across the 3 platforms (Windows, macOS, Linux):

So node.js downgrade won't work.

you read the wrong offical doc of Playwright-nodejs，but my question is playwright-python

[KotlinIsland]

Doesn't playwright install it's own node?

[phoenixor]

Doesn't playwright install it's own node?

you mean i just need to install Playwright-python and i got nodejs environment at the same time???

[KotlinIsland]

yep

[phoenixor]

yep

still don't work, maybe playwright-python can not work on win7

[mxschmitt]

@KotlinIsland which version of Windows are you using? Does it also reproduce for you when using Playwright normally? (instead of using the loop and pass etc)
