无法将Python库从一台电脑转移至另一台，求手动迁移方案

Got it, let's walk through how to manually transfer that Python library from your first PC to the second one when pip isn't cooperating. This guide is tailored for PyCharm users, so it should fit right into your workflow:

Wheel files are pre-compiled Python packages that let you install libraries without relying on pip to download them. Here's how to grab the exact version from your first computer:

• Open Command Prompt (Windows) or Terminal (macOS/Linux) on your original PC. If you used a virtual environment in PyCharm for this library, activate it first:
  • Windows: venv\Scripts\activate (navigate to your project's folder first if needed)
  • macOS/Linux: source venv/bin/activate
• Run this command to generate the wheel file for your target library. Replace your-library-name with the actual name of the package:

  pip wheel your-library-name -w ./wheel-exports
  

  This will save the library (and any dependencies it needs) as .whl files in a folder called wheel-exports. If you already have dependencies installed on the second PC, add --no-deps to skip downloading them:

  pip wheel your-library-name --no-deps -w ./wheel-exports
  

• Locate the wheel-exports folder—you'll see one or more .whl files here; these are the packages you need to transfer.

Use a USB drive, cloud storage, or a local network share to copy all the .whl files from the wheel-exports folder to an easy-to-find spot on your second PC (e.g., a folder on the desktop named transferred-packages).

You can install the package either through PyCharm's graphical interface or via the terminal—pick whichever you prefer:

Option 1: PyCharm GUI Installation #

• Open your project in PyCharm, then go to File > Settings > Project: [Your Project Name] > Python Interpreter (on macOS, this is PyCharm > Settings > Project: [Your Project Name] > Python Interpreter).
• Click the + button in the top-right corner of the interpreter window.
• Select Install from disk from the options that pop up.
• Browse to the folder where you saved the .whl files, select the correct one for your library, and click OK. Wait for the installation to finish, then click Apply and OK to close the settings.

Option 2: Terminal Installation (Faster for Multiple Packages) #

• Open the Terminal tab at the bottom of your PyCharm window.
• Activate your project's virtual environment (same command as Step 1):
  • Windows: venv\Scripts\activate
  • macOS/Linux: source venv/bin/activate
• Navigate to the folder with your transferred .whl files. For example:

  cd C:\Users\YourUsername\Desktop\transferred-packages
  

• Install the library with this command (replace your-library-file.whl with the actual filename):

  pip install your-library-file.whl
  

  If you have multiple dependency wheel files to install, you can install all of them at once:

  pip install *.whl
  

To make sure everything worked, check the Python Interpreter list in PyCharm—you should see the library listed with the exact version from your original PC. Alternatively, run this in the terminal:

pip show your-library-name

It should display the version number matching what you had on the first computer.
