Anaconda Python: where are the virtual environments stored?

If you activate the environment you're interested in, you can find that answer in the environment variables.

on MacOS/Linux:

source activate python35
echo $CONDA_PREFIX

on Windows:

conda activate python35
echo %CONDA_PREFIX%

You can also run conda info --envs, and that will show the paths to all your environments.

To get the path to the instance of python being used by a particular environment, do the following:

on MacOS/Linux:

source activate python35
which python

on Windows:

conda activate python35
where python

That should return the path you're looking for.

Your environments are located in Anaconda3\envs\<yourEnv_directory>\

To answer your question the folder for your python binaries and packages for the environment are located in ~Anaconda_installation_folder~/envs/python35.

But I cannot really say if that solves your problem. Normally you just switch to your environment source activate python35 and then type python. This will automatically give you the "right" python executable. So if you have a package you could use:

source activate python35
python setup.py install
# Now it is installed in your python35 environment
source activate python27
python setup.py install   
# Now it is also installed in your python27 environment

Just change python setup.py install to what you want to do in the environment. I don't have any experience using Sublime Text and what you mean with build system. But you can always use something like tox which automates a lot of these manual builds.

You can run the command conda info.

This will output something like this:

envs directories : C:\Users\Geo\.local\Miniconda3\envs
                   C:\Users\Geo\.conda\envs
                   C:\Users\Geo\AppData\Local\conda\conda\envs

I have installed conda at C:\Users\Geo\.local\Miniconda3.

Then with the command conda info -e you get the location of each environment.

(base) C:\Users\Geo>conda info -e
# conda environments:
#
miniconda2               C:\Users\Geo\.conda\envs\miniconda2
base                  *  C:\Users\Geo\.local\Miniconda3
anaconda3                C:\Users\Geo\.local\Miniconda3\envs\anaconda3
ml                       C:\Users\Geo\.local\Miniconda3\envs\ml
