[Bug] BrowserType.launch: Executable doesn't exist at /root/.cache/ms-playwright/chromium-1140/chrome-linux/chrome

[AngeloChecked]

Hi playwright guys,

This error occur with this release:

BrowserType.launch: Executable doesn't exist at /root/.cache/ms-playwright/chromium-1140/chrome-linux/chrome

Do you have any insights on this issue? Would you need additional information to assist with troubleshooting?

@AngeloChecked Are you running in docker? Any other details? The more information you can share, the better. Following the "Bug" issue template would be ideal!

oh, sorry!

version: 1.49.0 Expected Behavior: When attempting to open an HTML file using the Playwright Python library, it should generate a screenshot of the HTML using Chromium. Actual behavior: The library crashes with the following message:
Executable doesn't exist at /root/.cache/ms-playwright/chromium-1140/chrome-linux/chrome

It also displays a prompt:

Looks like Playwright was just installed or updated.       
Please run the following command to download new browsers: playwright install

However, running playwright install does not resolve the issue.

Additional context the playwright is executed inside docker the python library is playwright = "^1.48.0" My computer is a MacBook Pro with an M1 ARM processor.

OK, I found a temporary solution by fixing the version in the Dockerfile:
RUN npm install -g playwright@1.48.2

@AngeloChecked Thank you for details.

It seems like your playwright install and playwright uninstall commands are correctly installing chromium-1148 build which corresponds to playwright v1.49. This playwright is probably installed through npm install -g playwright line.

However, when you run your python script that uses playwright, it needs a different chromium-1140 build which corresponds to playwright v1.48. This playwright is probably installed because of playwright = "^1.48.0" requirement. I'd recommend to reconcile to a single playwright version, that should fix the problem.

@dgozman thank you!

I'll stick with this version for now while waiting for the next release: https://github.com/microsoft/playwright-python/releases
