Conda: Creating a virtual environment
Check if Conda is installed
conda -V
Check if Conda is up to date
conda update conda
Create a virtual environment
conda create -n yourenvname python=x.x anaconda
Activate your virtual environment
source activate yourenvname
Install additional Python packages to a virtual environment
conda install -n yourenvname [package]
Deactivate your virtual environment
source deactivate
Delete the virtual environment
conda remove -n yourenvname --all
I am not sure what causes the problem in your case, but code below works for me without any issues (OS X, the same version of Conda as yours).
Creation of the environment
conda create -n test_env python=3.6.3 anaconda
Some explanation of the documentation of conda create
is not clear:
-n test_env
sets name of the environment to test_envpython=3.6.3 anaconda
says that you want to use python in version 3.6.3 in this environment (exactly the one you have, and you can use a different one if you need it) and package anaconda. You can put all the things you need there, separated with spaces, e.g.,sqlite matplotlib requests
and specify their versions the same way as for python.
Activation
conda activate test_env
Deactivation
conda deactivate
Getting rid of it
conda remove -n test_env --all
I was able to solve my problem. Executing the source activate test_env
command wasn't picking up my .bash_profile
, and I normally work in tcsh. Simply starting a subprocess in Bash was enough to get activate
working. I guess I assumed, incorrectly, that the activate
command would start a child process in Bash and use Bash environment variables.
