playw.py does not contain lines that match the diff you provided!
Try again.
DO NOT skip blank lines, comments, docstrings, etc!
The diff needs to apply cleanly to the lines in playw.py!
playw.py does not contain these 7 exact lines in a row:

This diff adds a check before the main function to see if Chromium can be launched. If an exception occurs, it assumes Chromium is not installed and proceeds to install it using Playwright's command-line interface.

This diff removes the asynchronous code and replaces it with the synchronous version provided by Playwright's `sync_api`. The `async` and `await` keywords are removed, and the `async_playwright` context manager is replaced with `sync_playwright`. The script should now run synchronously.
# Aider chat conversation:
USER: write a playwright script to fetch the text from a url supplied on the cmd line
ASSISTANT: To create a Playwright script that fetches text from a URL supplied on the command line, I will write the necessary code in the `playw.py` file. The script will use Playwright's Python package to launch a browser, navigate to the provided URL, and print the text content of the page to the console.
Here is the diff for the new `playw.py` file:
```diff

```
This script will require the Playwright package to be installed. You can install it using `pip install playwright` and then run `playwright install` to install the necessary browser binaries. To run the script, use the command `python playw.py <URL>`, replacing `<URL>` with the actual URL you want to fetch text from.
