How to use virtualenv in makefile
I want to perform several operations while working on a specified virtualenv.
For example command

Is it possible?
In make you can run a shell as command. In this shell you can do everything you can do in a shell you started from comandline. Example:
install: ( \ source path/to/virtualenv/bin/activate; \ pip install -r requirements.txt; \ )
Attention must be paid to the
Everything between the open and close brace will be done in a single instance of a shell.
sio/Makefile.venv: Seamlessly manage Python virtual , Makefile.venv takes care of creating, updating and invoking Python virtual environment that you can use in your Makefiles. It will allow you to reduce venv related� It is always recommended to use a virtual environment while developing Python applications. To create a virtual environment, go to your project’s directory and run venv. If you are using Python 2, replace venv with virtualenv in the below commands. On macOS and Linux:
I like using something that runs only when
venv: venv/bin/activate venv/bin/activate: requirements.txt test -d venv || virtualenv venv . venv/bin/activate; pip install -Ur requirements.txt touch venv/bin/activate test: venv . venv/bin/activate; nosetests project/test clean: rm -rf venv find -iname "*.pyc" -delete

make runs every command in a recipe in a different subshell. However, setting
.ONESHELL: will run all the commands in a recipe in the same subshell, allowing you to activate a virtualenv and then run commands inside it.
.ONESHELL: applies to the whole Makefile, not just a single recipe. It may change behaviour of existing commands, details of possible errors in the full documentation. This will not let you activate a virtualenv for use outside the Makefile, since the commands are still run inside a subshell.

.ONESHELL: .PHONY: install install: source path/to/virtualenv/bin/activate pip install -r requirements.txt
Take five minutes to simplify your life with Make, For this reason, the makefile code will not work when copied directly from the post. I use GNU Make to automate my data processing pipelines. a virtualenv in the base directory (see VENV) make python-reqs install python� Makefile will run venv target only when you remove (or don’t have yet) virtual environment or you change setup.py. Because I use venv as a dependency for all tasks, I can change my Python dependencies and just run the tests. Makefile will ensure that a virtual environment is updated.
This is an alternate way to run things that you want to run in virtualenv.
BIN=venv/bin/ install: $(BIN)pip install -r requirements.txt run: $(BIN)python main.py
PS: This doesn't activate the virtualenv, but gets thing done. Hope you find it clean and useful.

How to Create a Minimal Makefile for Python Projects, activate virtual environment; install dependencies listed in the requirments.txt file; install the project (for development or testing); run tests; clean� So, to run your recipe make invokes a shell and passes it your virtualenv command, it works, then the shell exits, and your virtualenv is gone.
