I want to install python packages after virtualenv is created by conda. But I got the following error, does anyone know how to install packages into virtualenv created by conda ?

/Users/jzhang/anaconda/lib/python3.5/site-packages

Fetching package metadata .........


CondaEnvironmentNotFoundError: Could not find environment: /Users/jzhang/anaconda/envs/env_2 .
You can list all discoverable environments with `conda info --envs`.

I didn't use conda but as far as I understand from the docs, it should work like this:

1. Create your env conda create --name snowflakes biopython
2. Activate your env source activate snowflakes
3. Install what you need conda install what-you-want or pip install what-you-want

First, enter into an environment that you have created by the following command:

activate your_environment_name

Then, you will be in particular in your environment. Now, you can install numpy using this command:

conda install -c anaconda numpy
