How to Install Scrapy on Windows Without Hassle: Step‑by‑Step Guide

Scrapy is a fast, high‑level Python framework for web crawling and data extraction, useful for data mining, monitoring, and automated testing.

First, create a virtual environment in the desired folder, e.g. virtualenv --python=C:\Python34\python.exe scrapy_demo, naming it scrapy_demo.

Activate the environment by navigating to the Scripts directory inside scrapy_demo and running activate.bat. The command prompt will show the environment name in parentheses.

Install Scrapy with pip install Scrapy or, for faster downloads, use the Douban mirror: pip install -i https://pypi.douban.com/simple/ Scrapy. The installation proceeds quickly.

If a timeout occurs during installation, simply rerun the install command. Another common issue is a missing Twisted dependency.

To resolve the Twisted problem, download the appropriate wheel from https://www.lfd.uci.edu/~gohlke/pythonlibs/ , matching your Python version and system architecture, then install it with pip install Twisted-18.7.0-cp34-cp34m-win_amd64.whl. If the wheel is not supported, rename the .whl file to .zip, extract its contents into the virtual environment’s site-packages folder, and verify with pip list.

After fixing dependencies, reinstall Scrapy using the mirror command again. Finally, confirm a successful installation by running pip list and checking that Scrapy appears in the list.

Following these steps should allow you to install Scrapy on Windows without encountering the typical errors.
