PyVirtualenv

Usage

Activate a Python virtualenv in Julia REPL

julia> using PyVirtualenv
julia> PyVirtualenv.activate("PATH/TO/bin/python")
julia> using PyCall

Activate a Python virtualenv via Pipenv

julia> using PyVirtualenv
julia> PyVirtualenv.activate_pipenv("PATH/TO/Pipfile")
julia> using PyCall

Automate environment activation

In the directory $PROJECT where Project.toml and Pipfile exist, create a file called activate.jl with:

import Pkg
Pkg.activate(@__DIR__)
import PyVirtualenv
PyVirtualenv.activate_pipenv(@__DIR__)

Then you can start a Julia REPL with Julia and Python environments activated together by:

$ cd $PROJECT
$ julia -i activate.jl

To run a Julia script with all Julia and Python dependencies of $PROJECT, run

include("$PROJECT/activate.jl")

in the very beginning of the script.

Note that pkg> instantiate and shell> pipenv install still have to be run manually when using the project for the first time.
