Unable to install using pip install requirements.txt

I'm trying to install BitTornado for Python 2.7 using requirements.txt, I get the following error:

Collecting requirements.txt
  Could not find a version that satisfies the requirement requirements.txt (from versions: )
No matching distribution found for requirements.txt

Here is my code in requirements.txt:

-e git+https://github.com/effigies/BitTornado.git#egg=python2.7

I also tried -e git+https://github.com/effigies/[email protected] but still not working. Does someone know why is this happening?

Note: "python2.7" is the branch name

Thanks in Advance

The correct command is pip install -r requirements.txt. Note the -r option; without it, pip thinks you want to install a package named requirements.txt, which doesn't exist.

You forgot to add -r switch to specify that requirements.txt is the file with your dependencies.
