Two small — though important — changes 1. Since [the release of conda 4.6](https://www.anaconda.com/blog/conda-4-6-release), the [recommended way to activate a conda env](https://docs.conda.io/projects/conda/en/latest/user-guide/tasks/manage-environments.html#activating-an-environment) is to use `conda activate <myenv>`. 2. The [conda docs say](https://conda.io/projects/conda/en/latest/user-guide/tasks/manage-environments.html#exporting-an-environment-file-across-platforms) that the correct way to export an env is to use the `--from-history` flag. This only includes packages that you’ve explicitly asked for, and only "pins" versions when you asked to do so. If you use this flag, the "macOS-specific" packages probably won't appear.

# Conda environment with environment.yml

|
|
|
|
A Binder-compatible repo with an `environment.yml` file.
|
|
|

|
## Notes
|
|
The `environment.yml` file should list all Python libraries on which your notebooks
|
|
depend, specified as though they were created using the following `conda` commands:
|
|
|
|
```
|
|
conda activate example-environment
|
|
conda env export --from-history -f environment.yml
|
|
```
|
|
|
|
Note that the only libraries available to you will be the ones specified in
|
|
the `environment.yml`, so be sure to include everything that you need!
|
|
|
|
Also note that if you skip the `--from-history`, conda may include OS-specific
|
|
packages in `environment.yml`, which you would have to manually prune from
|
|
`environment.yml`. For example, confirmed macOS-specific packages that should
|
|
be removed are:
|
|
|
|
* libcxxabi=4.0.1
|
|
* appnope=0.1.0
|
|
* libgfortran=3.0.1
|
|
* libcxx=4.0.1
