ModuleNotFoundError: No module named 'pyquery'

pyquery is not installed in the running Python. Run python -m pip install pyquery. The PyPI name and the import name match (pyquery), so this is just a missing install.

The error

ModuleNotFoundError: No module named 'pyquery'

Fix it

1. Install pyquery

python -m pip install pyquery

Expected: Successfully installed pyquery-... with lxml and cssselect.

1. Confirm

python -c "from pyquery import PyQuery; print(PyQuery('hi').text())"

Expected: prints hi.

When this applies

• any pyquery import fails naming pyquery
• a fresh env for a jQuery-style scraping script

When it does NOT apply

• cannot import name 'etree' from 'lxml' means pyquery IS installed but lxml is broken (Python 3.12 vs old lxml)
• cannot import name 'PyQuery' from 'pyquery' is the shadowing problem

Compatibility

pyquery 2.x. Needs lxml; on Python 3.12+ make sure lxml is 4.9.3+.

Why it happens

The package was never installed into the active interpreter. pyquery scripts move between machines often, and the import is the first thing that notices.

Edge cases

• If the import then fails on etree from lxml, your lxml is too old for your Python. Upgrade lxml.
• pyquery is a thin wrapper over lxml. If lxml itself will not install on your platform, pyquery cannot work either.
