The following Python script provides an example: import sys import subprocess import _api as Conda # implement conda as a subprocess: subprocess.check_call([sys.executable, '-m', 'conda', 'install', If you’re working with Anaconda’s version of Python, you can also run Anaconda’s package manager (conda) as a subprocess in order to install Python packages. 'freeze']) installed_packages = for r in reqs.split()] print(installed_packages) ' ']) # process output with an API in the subprocess module: reqs = subprocess.check_output([sys.executable, '-m', 'pip', The following script will run pip as a subprocess to install one or more packages, and then print an updated list of installed packages: import sys import subprocess # implement pip as a subprocess: subprocess.check_call([sys.executable, '-m', 'pip', 'install', If you’re running the script interactively, it’s good practice to confirm the installation. If pip does not find a wheel to install, it will build one. The package, as well as any requirements will be installed. When it comes to automating the installation of Python packages, you can create a Python script that runs pip as a subprocess with just a few lines of code: import sys import subprocess # implement pip as a subprocess: subprocess.check_call([sys.executable, '-m', 'pip', 'install', Python Installation Checklistīefore packages can be installed, ensure that a Python installation containing the necessary files needed for installing packages is in place by following the Installation Requirements. However, PyPA fully supports using a Python script to run pip as a subprocess. When run as a thread from within a Python script, pip may affect non-pip code with unexpected results. Pip is not thread-safe, and is intended to be run as a single process.Use of a Python script to run pip to install a package is not supported by the Python Packaging Authority (PyPA) for the following reason: This resource provides examples of how to create a Python script that runs pip (the recommended package manager) or conda as a subprocess in order to install Python packages. In some cases, you may need to automate the updating of multiple Python deployments with a specific package or set of packages.
