2. Decompress the source code package in an offline environment and enter the decompressed directory.
3. Execute the following command in the decompressed directory to install:

python setup.py install

This command will install pip and its dependent packages in an offline environment.

Note:

1. When performing pip installation in an offline environment, you may encounter dependency problems. Before installation, you need to ensure that the required dependencies are installed.
2. If the Python version in the offline environment is inconsistent with that in the online environment, the installation may fail. Please confirm Python version compatibility before installation.
3. If other versions of pip have been installed in the offline environment, you need to uninstall the old version first and then install the new version.
4. You need to pay attention to the permissions of the machine in the offline environment to ensure that the installation operation can be performed.
