I'm trying to install automatically each library in python if it isn't installed.
#!/usr/bin/python
# -*- coding: utf-8 -*-
from pip._internal import main
pkgs = ['Bio==0.1.0','argparse==1.4.0']
for package in pkgs:
try:
import package
except ImportError:
main(['install', package])
But, this error occurs:
> Collecting Bio==0.1.0 Using cached
> https://files.pythonhosted.org/packages/14/c2/43663d53b93ef7b4d42cd3550631552887f36db02c0150d803c69ba636a6/bio-0.1.0-py2.py3-none-any.whl

> ERROR: Could not install packages due to an EnvironmentError: [Errno2] No such file or directory: '/tmp/pip-req-tracker-6sqtap8q/139713c65f8ac559a034717470dc5a6e30a6db86bdc3d69fe2bc0e63'
I notice that this occur always after the first library installation, e.g.: If I change ['Bio','argparse'] for ['argparse','Bio'], the argparse will be installed, and the Bio not.
