I'm using pip requirements files for keeping my dependency list. I also try to follow best practices for managing dependencies and provide precise package versions inside the requirements file. For example: Django==1.5.1 lxml==3.0 The question is: Is there a way to tell that there are any newer package versions available in the Python Package Index for packages listed inside requirements.txt ? For this particular example, currently latest available versions are 1.6.2 and 3.3.4 for Django and lxml respectively. I've tried pip install --upgrade -r requirements.txt , but it says that all is up-to

I have a requirements.txt file with a list of packages that are required for my virtual environment. Is it possible to find out whether all the packages mentioned in the file are present. If some packages are missing, how to find out which are the missing packages? Zaur Nasibov The pythonic way of doing it is via the pkg_resources API .

I'm trying to install Python libraries "grab" and "pycurl". I need to specify that pycurl be installed with option: "--with-nss". I can replicate the error on a completely clean virtual enviroment.

Developing a Django web app, I have a list of packages I need to install in a virtualenv. Say: Django==1.3.1 --extra-index-url=http://dist.pinaxproject.com/dev/ Pinax==0.9b1.dev10 git+git://github.com/pinax/pinax-theme-bootstrap.git@cff4f5bbe9f87f0c67ee9ada9aa8ae82978f9890 # and other packages Initially I installed them manually, one by one, along the development.
