Help installing playwright

Hello,

I'm trying to install Playwright and I'm really not very sure what I'm doing.

Per the docs: https://github.com/microsoft/playwright-python#evaluate-js-in-browser

One must perform 2 steps: pip install playwright python -m playwright install

I've pip installed playwright on my python3.8 virtual env but am unable to complete the second step. I've tried to cd into the directories that contain playwright prior to entering the "python -m playwright install" command but am getting the following:

(

my-virtualenv) 20:48 ~/.local/lib/python3.8/site-packages/playwright $ cd /home/nweather2/.local/lib/python3.8/site-packages/playwright
(my-virtualenv) 20:48 ~/.local/lib/python3.8/site-packages/playwright $ python -m playwright install
Traceback (most recent call last):

    return _run_code(code, main_globals, None,
  File "/usr/lib/python3.8/runpy.py", line 85, in _run_code
    exec(code, run_globals)
  File "/home/nweather2/.local/lib/python3.8/site-packages/playwright/playwright.py", line 17, in <module>
    from playwright.browser_type import BrowserType

    from playwright.browser_type import BrowserType
ModuleNotFoundError: No module named 'playwright.browser_type'; 'playwright' is not a package

Can anyone help?

Thanks.

How did you install that package? Installation in .local is not the installation in your virtual environment. Why did you change the directory?

Thanks for your response, I initially changed the directory because I couldn't get it to work without doing so - I was getting the same error, anyways, I razed that venv, made another and seem to be in good shape. Thanks.
