Automatically create requirements txt

Question

There are times when I install the source code of Python from github but am clueless as to how to install the dependencies. If there is no requirements.txt file I have to create it by hand. My question is given the python source code directory, will it be possible to create requirements.txt automatically from the import section?

Answer 1

You can use the following code to generate a requirements.txt file:

pip install pipreqs pipreqs /path/to/project

Sometimes you come across pip freeze, but this saves all your packages in the environment including those that you don't use in your current project.
