Installing Python Modules Programmatically
The need to install packages from PyPI within the confines of scripts often arises. Many solutions exist, but it is crucial to adhere to the officially sanctioned method: leveraging pip's command-line interface through a subprocess.
Using the sys.executable variable ensures that the pip associated with the current runtime will be summoned.
import subprocess import sys def install(package): subprocess.check_call([sys.executable, "-m", "pip", "install", package])
By employing this approach, the installation process becomes secure and reliable, adhering to the recommended guidelines established by pip.
The above is the detailed content of How Can I Programmatically Install Python Packages Using pip?. For more information, please follow other related articles on the PHP Chinese website!
