PyCharm reveals the methods and techniques of adding libraries

PyCharm is a powerful Python integrated development environment that provides Python developers with a wealth of functions and tools . During development with PyCharm, adding libraries is a common requirement. This article will introduce in detail the methods and techniques of adding libraries to PyCharm, including installing libraries through PyCharm's own functions and using the pip tool.

1. Add libraries through PyCharm’s own functions

PyCharm provides a convenient and fast way to manage and add libraries. The following are the specific steps:

  1. Open PyCharm, enter the project interface.
  2. Click "File" on the top menu bar and select "Settings" to enter the settings interface.
  3. In the settings interface, select "Project: [Project Name]", and then click "Project Interpreter".
  4. On the Project Interpreter page, you can see the Python interpreter and installed libraries used by the current project.
  5. Click the plus sign " " on the right, select "Search", enter the name of the library you want to add in the search box, and then click "Install Package".
  6. PyCharm will automatically download and install the required libraries, and once the installation is complete, you can use the library in your project.

2. Use the pip tool to install the library

In addition to adding libraries through PyCharm's own functions, you can also use the pip tool to install the library on the command line and then use it in PyCharm . The following are the specific steps:

  1. Open the terminal or command line interface.
  2. Enter the following command to install the required libraries (taking the requests library as an example):

    pip install requests
  3. After the installation is completed, return to PyCharm and introduce the library into the project. be usable.

3. Common problems and solutions for adding libraries

In the process of adding libraries, you may encounter some common problems. The following will introduce several common problems and their solutions. Method:

  1. The added library cannot be imported normally: This may be due to incorrect path configuration or the library is not installed correctly. The solution is to check the path configuration and reinstall the library.
  2. Permission issues occur when installing the library: When using pip to install the library, an insufficient permission error may occur. The workaround is to run the terminal as administrator or install using a virtual environment.

4. Tips for adding libraries

In addition to the basic methods of adding libraries, there are also some techniques that can improve development efficiency:

  1. Use requirements. txt file: Write the libraries required for the project into the requirements.txt file to quickly install all dependent libraries.
  2. Use virtual environment: Establish a virtual environment to manage project dependency libraries, which can avoid conflicts between different projects.

Through the methods and techniques introduced in this article, I believe readers have mastered the various ways of adding libraries to PyCharm. In actual development, choosing the appropriate method to add libraries according to needs can complete the project more efficiently. I hope this article is helpful to all Python developers!

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
