Quickly master the basic knowledge of PyCharm project packaging

Start from scratch and quickly get started with PyCharm project packaging skills

Overview:
In Python development, packaging the project into an executable file is a very important step . It makes it easy to share and distribute projects without installing a Python interpreter and dependency packages. As a powerful Python integrated development environment, PyCharm provides tips and tools for quickly getting started with project packaging. This article will introduce how to use PyCharm to package your Python project from scratch and provide specific code examples.

Preparation:
Before you start, make sure you have installed PyCharm and successfully created a Python project. Next, we will do the following step by step.

Step 1: Create the setup.py file
Open PyCharm, right-click the project folder, select "New" -> "File", and name the file "setup.py". This is a Python file that describes the project's metadata and packaging configuration.

from setuptools import setup

setup(
    name="project_name",
    version="1.0",
    author="Your Name",
    author_email="your_email@example.com",
    description="Description of your project",
    packages=["package1", "package2"],
    install_requires=["package1", "package2"],
    entry_points={
        "console_scripts": [
            "my_command=my_package.__main__:main",
        ],
    },
)

In the above sample code, you need to modify the following:

• name: project name
• version: project version number
• author : Author name
• author_email: Author contact email
• description: Project description
• packages: List of packages that need to be included in the project
• install_requires: Project dependencies package list
• entry_points: The command line entry of the project, which can be started through the my_command command to start the main function# of
my_package

##Step 2: Configure PyCharm

Click "Run" -> "Edit Configurations" in the menu bar at the top of PyCharm, click the " " button in the pop-up window, and select "Python" -> "Python Script". Select the setup.py file in "Script path" and add
bdist_egg in "Script parameters", then click "OK" to save.

Step 3: Package the project

Click "Run" -> "Run..." in the menu bar at the top of PyCharm to select the Python script run configuration you just configured, and click "OK". PyCharm will automatically perform the packaging operation and generate a folder named "dist" under the project folder, which contains the packaged egg file.

Step 4: Test the packaging result

Open the terminal in the project folder and run the following command to install the project's egg file:

pip install dist/project_name-1.0-py3.8.egg

Note that you need to install the project's egg file according to your project name and Modify the version number of the above command. Then, you can use your project in the Python environment.

Conclusion:

By using the quick-start project packaging skills provided by PyCharm, you can easily package Python projects into executable files. This article describes the entire process from creating the setup.py file to packaging the project, and provides detailed code examples. I hope this article can help you successfully package your Python project and better share and distribute your code. Happy studying!
