  1. You are missing -r command flag, so go again with:

    pip install -r requirements.txt

    As it was before, pip just try to get requirements-txt from remote store expecting it to be a package name.

    See pip help install

    Usage:

      pip install [options] <requirement specifier> [package-index-options] ...
  pip install [options] -r <requirements file> [package-index-options] ...

...
  pip also supports installing from "requirements files", which provide
  an easy way to specify a whole environment to be installed.

    Install Options: 

      -r, --requirement <file>    Install from the given requirements file. This option
                              can be used multiple times.

  2. pip3 install -r requirements.txt

    or

    pip install -r requirements.txt

    would help
