Pip Wheel and coverage: command not found error

Question

I want to use wheels on my Linux server as it seems much faster, but when I do:

pip install wheel    
pip wheel -r requirements_dev.txt

Which contains the following packages

nose
django_coverage
coverage

I get coverage: command not found, it's like it is not being installed.

Is there a fallback if a wheel is not found to pip install or have I not understood/setup this correctly?

Answer 1

Can you try this?

virtualenv venv
source venv/bin/activate
pip -r install requirement.txt

Also getting this with using wheel:-

pip wheel -r check.txt
Collecting nose (from -r check.txt (line 1))
  Using cached nose-1.3.7-py2-none-any.whl
  Saved ./nose-1.3.7-py2-none-any.whl
Collecting django_coverage (from -r check.txt (line 2))
  Saved ./django_coverage-1.2.4-cp27-none-any.whl
Collecting coverage (from -r check.txt (line 3))

Skipping nose, due to already being wheel.
Skipping django-coverage, due to already being wheel.
