ModuleNotFoundError: No module named 'playwright_stealth'

playwright-stealth is not installed in the running Python. The PyPI name is playwright-stealth (dash), the import is playwright_stealth (underscore). Run python -m pip install playwright-stealth. If your code uses stealth_sync, also pin below 2.0 (see the companion skill), or the next error you meet is the removed-helper one.

The error

ModuleNotFoundError: No module named 'playwright_stealth'

Fix it

1. Install playwright-stealth

python -m pip install playwright-stealth

Expected: Successfully installed playwright-stealth-....

1. Confirm

python -c "import playwright_stealth; print('ok')"

Expected: prints ok.

1. If your code imports stealthsync/stealthasync, pin the 1.x line

python -m pip install 'playwright-stealth<2.0.0'

Expected: the helper imports work. 2.x removed them.

When this applies

• any playwrightstealth import fails naming `playwrightstealth`
• a bot script moved to a fresh env

When it does NOT apply

• cannot import name 'stealth_sync' with the package present is the 2.x API removal

Compatibility

playwright-stealth 1.x/2.x. Remember the 2.0.0 breaking change when choosing which line to install.

Why it happens

The package was never installed into the active interpreter, and the dash/underscore split (pip install playwright-stealth, import playwright_stealth) stalls people at the install step. The follow-on trap is installing 2.x into 1.x-era code.

Edge cases

• pip install playwright_stealth (underscore) does not exist on PyPI. Use the dash form.
• playwright-stealth needs playwright itself installed and its browsers downloaded. Those are separate steps.
