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

Question

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 everyone:

pip install -r /path/to/requirements.txt
