When Can the -e Option Prove Useful in pip install?

Usefulness of the -e Option with pip install

In certain situations, the -e (or --editable) option proves invaluable when executing pip install. This is particularly true when dealing with local projects during development.

How -e Works

As per the pip documentation, the -e option enables "editable mode." In this mode, the package is installed with a link to its original location. As a result, any changes made to the original package are automatically reflected in the installed package.

Why Use -e?

The primary use case for -e is during local package development. By installing the package in editable mode, developers can make changes to the code, save them, and see the updates reflected immediately in their environment. This eliminates the need to reinstall the package after every modification, significantly speeding up the development process.

Example Usage

To install a package locally using -e, provide the following command:

pip install -e .

Alternatively, if the package is located at a specific path, use the full path to the setup.py file:

pip install -e ~/ultimate-utils/ultimate-utils-proj-src/

Conclusion

The -e option in pip install serves as a valuable tool for local package development. By linking the installed package to its original location, it eliminates the need for constant reinstallation and allows developers to iterate quickly on their code.
