Как использовать pip3 install -r?

Question

[link_vrb]

Когда я ввожу pip3 install -r myfile.py мне выводит:

Invalid requirement: 'import argparse'
Traceback (most recent call last):
  File "/usr/share/python-wheels/packaging-17.1-py2.py3-none-any.whl/packaging/requirements.py", line 93, in __init__
    req = REQUIREMENT.parseString(requirement_string)
  File "/usr/share/python-wheels/pyparsing-2.2.0-py2.py3-none-any.whl/pyparsing.py", line 1632, in parseString
    raise exc
  File "/usr/share/python-wheels/pyparsing-2.2.0-py2.py3-none-any.whl/pyparsing.py", line 1622, in parseString
    loc, tokens = self._parse( instring, 0 )
  File "/usr/share/python-wheels/pyparsing-2.2.0-py2.py3-none-any.whl/pyparsing.py", line 1379, in _parseNoCache
    loc,tokens = self.parseImpl( instring, preloc, doActions )
  File "/usr/share/python-wheels/pyparsing-2.2.0-py2.py3-none-any.whl/pyparsing.py", line 3395, in parseImpl
    loc, exprtokens = e._parse( instring, loc, doActions )
  File "/usr/share/python-wheels/pyparsing-2.2.0-py2.py3-none-any.whl/pyparsing.py", line 1383, in _parseNoCache
    loc,tokens = self.parseImpl( instring, preloc, doActions )
  File "/usr/share/python-wheels/pyparsing-2.2.0-py2.py3-none-any.whl/pyparsing.py", line 3183, in parseImpl
    raise ParseException(instring, loc, self.errmsg, self)
pyparsing.ParseException: Expected stringEnd (at char 7), (line:1, col:8)

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/pip/req/req_install.py", line 82, in __init__
    req = Requirement(req)
  File "/usr/share/python-wheels/packaging-17.1-py2.py3-none-any.whl/packaging/requirements.py", line 97, in __init__
    requirement_string[e.loc:e.loc + 8]))
pip._vendor.packaging.requirements.InvalidRequirement: Invalid requirement, parse error at "'argparse'"

Как сделать чтобы работало нормально?

Вместо myfile.py должен быть что-то типа requirements.txt, в котором просто перечислен список пакетов, которые нужно установить
