Could not find a version that satisfies the requirement package

Question

I m installing several Python packages in Ubuntu 12 04 using the following requirements txt file   numpy gt  1 8 2  lt 2 0 0 matplotlib gt  1 3 1  lt 2 0 0 scipy gt  0 14 0  lt 1 0 0 astroML gt  0 2  lt 1 0 scikit-learn gt  0 14 1  lt 1 0 0 rpy2 gt  2 4 3  lt 3 0 0   and these two commands     pip install --download  tmp -r requirements txt   pip install --user --no-index --find-links  tmp -r requirements txt    the first one downloads the packages and the second one installs them    The process is frequently stopped with the error     Could not find a version that satisfies the requirement  lt package gt   from matplotlib lt 2 0 0  gt  1 3 1- gt -r requirements txt  line 2    from versions    No matching distribution found for  lt package gt   from matplotlib lt 2 0 0  gt  1 3 1- gt -r requirements txt  line 2     which I fix manually with   pip install --user  lt package gt    and then run the second pip install command again   But that only works for that particular package  When I run the second pip install command again  the process is stopped now complaining about another required package and I need to repeat the process again  ie  install the new required package manually  with the command above  and then run the second pip install command   So far I ve had to manually install six  pytz  nose  and now it s complaining about needing mock   Is there a way to tell pip to automatically install all needed dependencies so I don t have to do it manually one by one   Add  This only happens in Ubuntu 12 04 BTW  In Ubuntu 14 04 the pip install commands applied on the requirements txt file work without issues

Although it doesn t really answers this specific question  Others got the same error message with this mistake  For those who like me initial forgot the -r  Use pip install -r requirements txt the -r is essential for the command  The original answer  https   stackoverflow com a 42876654 10093070

Try installing flask through the powershell using the following command   pip install --isolated Flask   This will allow installation to avoide environment variables and user configuration

Not always  but in some cases the package already exists  For example - getpass  It is not listed by  pip list  but it can be imported and used     If I try to pip install getpass I get the following error   Could not find a version that satisfies the requirement getpass

This approach  having all dependencies in a directory and not downloading from an index  only works when the directory contains all packages  The directory should therefore contain all dependencies but also all packages that those dependencies depend on  e g   six  pytz etc    You should therefore manually include these in requirements txt  so that the first step downloads them explicitly  or you should install all packages using PyPI and then pip freeze  gt  requirements txt to store the list of all packages needed

Same error in slightly different circumstances  on MacOs  Apparently setuptools versions past 45 can expose some issues and this command got me past it  pip3 install setuptools  45
