How can I install packages using pip according to the requirements.txt file from a local directory?

Here is the problem: I have a requirements.txt file that looks like: BeautifulSoup==3.2.0 Django==1.3 Fabric==1.2.0 Jinja2==2.5.5 PyYAML==3.09 Pygments==1.4 SQLAlchemy==0.7.1 South==0.7.3 amqplib==0.6.1 anyjson==0.3 ... I have a local archive directory containing all the packages + others. I have created a new virtualenv with bin/virtualenv testing Upon activating it, I tried to install the packages according to requirements.txt from the local archive directory. source bin/activate pip install -r /path/to/requirements.txt -f file:///path/to/archive/ I got some output that seems to indicate that the installation is fine: Downloading/unpacking Fabric==1.2.0 (from -r ../testing/requirements.txt (line 3)) Running setup.py egg_info for package Fabric warning: no previously-included files matching '*' found under directory 'docs/_build' warning: no files found matching 'fabfile.py' Downloading/unpacking South==0.7.3 (from -r ../testing/requirements.txt (line 8)) Running setup.py egg_info for package South .... But a later check revealed that none of the packages are installed properly. I cannot import the packages, and none are found in the site-packages directory of my virtualenv. So what went wrong?
This works for me: pip install -r requirements.txt --no-index --find-links file:///tmp/packages --no-index - Ignore package index (only look at --find-links URLs instead). -f, --find-links <URL> - If <URL> is a URL or a path to an HTML file, then parse for links to archives. If <URL> is a local path or a file:// URL that's a directory, then look for archives in the directory listing.
