Unable to install using pip install requirements.txt

Question

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/BitTornado.git@python2.7 but it still is not working. Does someone know why is this happening?

Note: "python2.7" is the branch name

Please show the exact pip command you ran. – Daniel Roseman Mar 18 '17 at 16:04 — Daniel Roseman, Mar 18 '17 at 16:04
It's "pip install requirements.txt" – Avdhesh Parashar Mar 18 '17 at 16:07 — Avdhesh Parashar, Mar 18 '17 at 16:07
`pip install -r requirements.txt` – mic4ael Mar 18 '17 at 16:07 — mic4ael, Mar 18 '17 at 16:07
Thanks @mic4ael. I don't know how I missed -r argument! – Avdhesh Parashar Mar 18 '17 at 16:11 — Avdhesh Parashar, Mar 18 '17 at 16:11

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.

Thanks @jwodder, with -r option, it says git command not found. Does it mean I have to install git on my system and without it, it can not be installed? – Avdhesh Parashar Mar 18 '17 at 16:10
@AvdheshParashar: Yes. – jwodder Mar 18 '17 at 16:11
Is there any other way I could install git hosted library without having to use command `git clone ....`. I also tried dependency_links in setup.py but it is deprecated now. – Avdhesh Parashar Mar 18 '17 at 16:17
@AvdheshParashar: Go to https://github.com/effigies/BitTornado, click "Clone or download", click "Download ZIP", and run `pip install /path/to/zip/file/you/just/downloaded` – jwodder Mar 18 '17 at 16:38
Thanks @jwodder, I did that already but I want to install it using code, not manually – Avdhesh Parashar Mar 18 '17 at 16:56
@AvdheshParashar: `pip install https://github.com/effigies/BitTornado/archive/python2.7.zip` – jwodder Mar 18 '17 at 18:45
You saved me :D – Kavinda Jayakody Feb 20 '20 at 19:16

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