Installation guide

This document describes how to install Scrapy on Linux, Windows and Mac OS X systems and it consists of the following 3 steps:

If you use Ubuntu (9.10 or above), you can use the Ubuntu packages to install Scrapy more easily, skipping these steps. The Ubuntu packages are also kept updated with latest bug fixes.


  • Python 2.5, 2.6, 2.7 (3.x is not yet supported)
  • Twisted 2.5.0, 8.0 or above (Windows users: you’ll need to install Zope.Interface and maybe pywin32 because of this Twisted bug)
  • libxml2 (versions prior to 2.6.28 are known to have problems parsing certain malformed HTML, and have also been reported to contain leaks, so 2.6.28 or above is highly recommended)


Step 1. Install Python

Scrapy works with Python 2.5, 2.6 or 2.7, which you can get at

Step 2. Install required libraries

The procedure for installing the required third party libraries depends on the platform and operating system you use.


If you’re running Ubuntu/Debian Linux, run the following command as root:

apt-get install python-twisted python-libxml2

To install optional libraries:

apt-get install python-pyopenssl python-simplejson

Arch Linux

If you are running Arch Linux, run the following command as root:

pacman -S twisted libxml2

To install optional libraries:

pacman -S pyopenssl python-simplejson

Mac OS X

First, download Twisted for Mac.

Mac OS X ships an libxml2 version too old to be used by Scrapy. Also, by looking on the web it seems that installing libxml2 on MacOSX is a bit of a challenge. Here is a way to achieve this, though not acceptable on the long run:

  1. Fetch the following libxml2 and libxslt packages:

  2. Extract, build and install them both with:

    ./configure --with-python=/Library/Frameworks/Python.framework/Versions/2.5/
    sudo make install

    Replacing /Library/Frameworks/Python.framework/Version/2.5/ with your current python framework location.

  3. Install libxml2 Python bidings with:

    cd libxml2-2.7.3/python
    sudo make install

    The libraries and modules should be installed in something like /usr/local/lib/python2.5/site-packages. Add it to your PYTHONPATH and you are done.

  4. Check the libxml2 library was installed properly with:

    python -c 'import libxml2'


Download and install:

  1. Twisted for Windows - you may need to install pywin32 because of this Twisted bug
  2. Install Zope.Interface (required by Twisted)
  3. libxml2 for Windows
  4. PyOpenSSL for Windows

Step 3. Install Scrapy

There are three ways to download and install Scrapy:

  1. Installing an official release
  2. Installing with easy_install
  3. Installing the development version

Installing an official release

Download Scrapy from the Download page. Scrapy is distributed in two ways: a source code tarball (for Unix and Mac OS X systems) and a Windows installer (for Windows). If you downloaded the tarball, you can install it as any Python package using

tar zxf scrapy-X.X.X.tar.gz
cd scrapy-X.X.X
python install

If you downloaded the Windows installer, just run it.


In Windows, you may need to add the C:\Python25\Scripts (or C:\Python26\Scripts) folder to the system path by adding that directory to the PATH environment variable from the Control Panel.

Installing with easy_install

You can install Scrapy running easy_install like this:

easy_install -U Scrapy

Installing the development version


If you use the development version of Scrapy, you should subscribe to the mailing lists to get notified of any changes to the API.

  1. Check out the latest development code from the Mercurial repository (you need to install Mercurial_ first):

    hg clone scrapy-trunk
  1. Add Scrapy to your Python path

    If you’re on Linux, Mac or any Unix-like system, you can make a symbolic link to your system site-packages directory like this:

    ln -s /path/to/scrapy-trunk/scrapy SITE-PACKAGES/scrapy

    Where SITE-PACKAGES is the location of your system site-packages directory. To find this out execute the following:

    python -c "from distutils.sysconfig import get_python_lib; print get_python_lib()"

    Alternatively, you can define your PYTHONPATH environment variable so that it includes the scrapy-trunk directory. This solution also works on Windows systems, which don’t support symbolic links. (Environment variables can be defined on Windows systems from the Control Panel).

    Unix-like example:


    Windows example (from command line, but you should probably use the Control Panel):

    set PYTHONPATH=C:\path\to\scrapy-trunk
  2. Make the scrapy command available

    On Unix-like systems, create a symbolic link to the file scrapy-trunk/bin/scrapy in a directory on your system path, such as /usr/local/bin. For example:

    ln -s `pwd`/scrapy-trunk/bin/scrapy /usr/local/bin

    This simply lets you type scrapy from within any directory, rather than having to qualify the command with the full path to the file.

    On Windows systems, the same result can be achieved by copying the file scrapy-trunk/bin/scrapy to somewhere on your system path, for example C:\Python25\Scripts, which is customary for Python scripts.
