pip install editable package dir

Certainly! Let's create a tutorial on using pip install -e with a package_dir option. This is useful when you want to install a Python package in "editable" mode, meaning that changes to the source code will immediately affect the installed package without requiring a reinstallation.
In Python development, it's common to work on projects that consist of multiple packages or modules. The need for an editable installation arises when you want to make changes to the source code of a package and see the effects immediately without reinstalling the package. The pip install -e command, along with the package_dir option, allows developers to achieve this.
Create a simple Python project with the following directory structure:
Open a terminal in the project root and run the following command to install the package in editable mode:
The dot . at the end indicates the current directory.
Now, you can make changes to the source code in the my_package directory. Any changes you make will immediately affect the installed package.
In this example, the source code is in a subdirectory named src. Adjust the value accordingly.
Using pip install -e with the package_dir option is a convenient way to work on Python projects, especially when dealing with multiple packages or source code in subdirectories. It enables you to make changes to the code and see the effects immediately without the need for reinstallations.
