The problem originates when I start by cloning a git project that uses pipenv, so it has a Pipfile + Pipfile.lock. I want to use a virtual environment with the project so I run pipenv shell
. I now have a virtual environment created and I am inside the virtual environment. The project obviously has a lot of dependencies (listed in the Pipfile). I don't want to have to go through the list in the Pipfile one by one and install them using pipenv install <package_name>
. Is there a pipenv/pip command that installs all the packages from a Pipfile I already have? Or maybe I need to set up the environment differently than running pipenv shell
?
$ pipenv lock is used to create a Pipfile. lock , which declares all dependencies (and sub-dependencies) of your project, their latest available versions, and the current hashes for the downloaded files.
pip will grow a new command line option, -p / --pipfile to install the versions as specified in a Pipfile , similar to its existing -r / --requirement argument for installing requirements. txt files. To manually update the Pipfile.
Open a console in your project directory and type pipenv install <package_name> to install a package for the project. To specify that the package is for development, use the -d flag. You can use pip syntax to denote a specific version of a package (e.g., black==13.0b1 ).
The proper answer to this question is that pipenv install
or pipenv install --dev
(if there are dev dependencies) should be ran. That will install all the dependencies in the Pipefile. Putting the dependencies into a requirements.txt and then using pip will work but is not really necessary. The whole point of using pipenv for most people is to avoid the need to manage a requirements.txt or to use pip.
EDIT: if the virtualenv is already activated, you can also use pipenv sync
or pipenv sync --dev
for the same effect.
Ideally, you are encouraged to have a requirements.txt
file which contains all the packages required for installation via pip. You can create this file by doing:
pip freeze > requirements.txt
You can convert a Pipfile and Pipfile.lock into a requirements.txt. Take a look into this
pipenv lock -r
After that, you can install all your modules in your python virtual environment by doing the following:
pip install -r requirements.txt
Hopefully, I anwered your question.
