Note: Cloud SDK uses Python 2 by default, but will soon move to Python 3 (run gcloud topic startup for exclusions and more information on configuring your Python interpreter to use a different version). Warning: This library doesn't support App Engine Standard environment for Python 2.7. For more information, see Using PHP on Google Cloud. npm install --save @google-cloud/storage PHP. composer require google/cloud-storage Python. . While Cloud SDK currently uses Python 2 by default, you can use an existing Python installation if necessary by unchecking the option to 'Install Bundled Python'. For more information, see Setting Up a Python Development Environment.
