python automatically generates the requirements file for the current project

there are several ways:

1. Use PIP freeze

< pre style=”margin: 0px 0px 15px; padding: 0px; font-family: “Courier New” ! important; font-size: 12px ! important; The line – height: 1.72222; color: inherit; white-space: pre; border-radius: 6px; overflow-wrap: break-word;” > pip freeze > requirements.txt< /pre>

this way is to list the packages in the entire environment, if it is a virtual environment. In general, we only need to export the current project’s requirement.txt, and pipreqs

is a helpful tool that scans the project directory to automatically discover which libraries are used, automatically generates dependency listings, and only generates project-related dependencies to requirements. TXT

installation

< pre style=”margin: 0px 0px 15px; padding: 0px; font-family: “Courier New” ! important; font-size: 12px ! important; The line – height: 1.72222; color: inherit; white-space: pre; border-radius: 6px; overflow-wrap: break-word;” > pip install pipreqs< /pre>

Use

also easy to use pipreqs pathname
here goes directly to the project root directory, so it is./
