[Python-modules-team] python virualenv

[Rainer Dorsch]

Hello,

I have a quite basic questions on virtualenv for python/pip:

If I run it as shown in the example below, I see that binaries which come with 
pip installed packages in a virtualenv go into the ~/.local/bin directory and 
not into the <virtualenv>/bin directory.  E.g. shown here

 The script plasma_store is installed in '/home/rd/.local/bin' which is not on 
PATH. 
 Consider adding this directory to PATH or, if you prefer to suppress this 
warning, use --no-warn-script-location.                                                                                                                                                                                   

I am just wondering if there is a good reason for that. If all the effort is 
already done, why not storing all parts in virtualenv environment?

Here is the full sequence I executed:
