[Question]: Getting error `FileNotFoundError: [Errno 2] No such file or directory: '/Users/my_user/.pyenv/versions/pwright_new/lib/python3.9/site-packages/playwright/driver/playwright-cli'`

Your question

I just installed playwright and tried running the example script as per the readme but I am getting an error:

my script:

import asyncio
from playwright.async_api import async_playwright

async def main():
    async with async_playwright() as p:
        for browser_type in [p.chromium, p.firefox, p.webkit]:
            browser = await browser_type.launch()
            page = await browser.new_page()
            await page.goto('http://whatsmyuseragent.org/')
            await page.screenshot(path=f'example-{browser_type.name}.png')
            await browser.close()

asyncio.run(main())

--no-cache-dir and uninstall etc. is I think not required. Only pip install --upgrade pip

[mxschmitt]

Awesome, TL;DR was that the PIP version which you were using did not support the package file naming which we use to distribute. After upgrading PIP it works as expected.

We can add pip install --upgrade pip in our intro: https://github.com/microsoft/playwright/blob/master/docs/src/intro-python.md

(I would add it before we run the pip install playwright command.
