Usage Examples: Create a new project using Python 3.7, specifically: $ pipenv --python 3.7 Remove project virtualenv (inferred from current directory): $ pipenv --rm Install all dependencies for a project (including dev): $ pipenv install --dev Create a lockfile containing pre-releases: $ pipenv lock --pre Show a graph of your installed dependencies: $ pipenv graph Check your installed dependencies for security vulnerabilities: $ pipenv check Install a local setup.py into your virtual environment/Pipfile: $ pipenv install -e . Use a lower-level pip command: $ pipenv run pip freeze Commands: check Checks for PyUp Safety security vulnerabilities and against PEP 508 markers provided in Pipfile. clean Uninstalls all packages not specified in Pipfile.lock. graph Displays currently-installed dependency graph information. install Installs provided packages and adds them to Pipfile, or (if no packages are given), installs all packages from Pipfile. lock Generates Pipfile.lock. open View a given module in your editor. requirements Generate a requirements.txt from Pipfile.lock. run Spawns a command installed into the virtualenv. scripts Lists scripts in current environment config. shell Spawns a shell within the virtualenv. sync Installs all packages specified in Pipfile.lock. uninstall Uninstalls a provided package and removes it from Pipfile. update Runs lock, then sync. upgrade Resolves provided packages and adds them to Pipfile, or (if no packages are given), merges results to Pipfile.lock verify Verify the hash in Pipfile.lock is up-to-date.
