How to install module from another python installation

Question

I am using winpython. Now for simple distribution, I want to use winpython zero. Is it possible to install the package from winpython folder to winpython zero folder?

• Rahul: Or, nobody uses winpython?

Answer 1

In theory, a possible way would be to:

• download packages from https://sourceforge.net/projects/winpython/files/WinPython_Source/Do_It_Yourself/Winpython_2016-03/

• unzip them all in d:\toto

• then do

pip install the_package_i_want --no-index --find-links=d:\toto --trusted-host=None

Answer 2

One of the simplest ways is just copying the site-package directory in the original winpython to the new one (It is assumed that the versions of two winpythons are the same, saying python 3.5).

If you thinks the above way is silly, then you can use pip instead.

1. Extract the installed packages from original winpython (pip used below should belong to the original winpython)

   pip freeze --all> python_packages.txt

2. Install the extracted package list with pip. (pip used below should belong to the new winpython)

   pip install -r python_packages.txt

• Rahul: I don't want to download the package so pip will not help. Thanks for the answer. I have winpython which contains all installed package. Is it possible to extract that package and install it to the another python installtion?
