How to install pip offline without internet

How to install pip without a network requires specific code examples

With the widespread application of Python, pip has become a standard tool for Python package managers. However, installing pip can become difficult without an internet connection. This article will introduce two methods to solve the problem of installing pip in a non-network environment, and provide detailed code examples.

Method 1: Offline installation
If you cannot connect to the Internet, you can try to use the offline installation method to install pip. First, you need to download the pip installation package from a computer with an Internet connection and copy it to the target machine without an Internet connection. The following are the specific steps:

1. On a machine with an Internet connection, open the browser and search for "pip installation package download" to find a trustworthy website and download pip for your operating system Installation package (usually a .whl file).
2. Copy the downloaded pip installation package to any directory of the target machine without network connection, such as /home/user/.
3. Open the command line terminal on the target machine and enter the directory where the pip installation package is located. Install pip using the following command:

python -m pip install pip-<version>.whl

Be sure to replace <version> with the version number of the pip installation package you downloaded. After executing the above command, pip will be successfully installed on your machine.

Method 2: Manual installation
If the offline installation method is not applicable or unsuccessful, you can try to install pip manually. The following are the specific steps:

1. On a machine with a network connection, open the browser and search for "pip source code download", find a trustworthy website and download the source code of pip (usually .tar. gz or .zip file).
2. Copy the downloaded pip source code to any directory of the target machine without network connection, such as /home/user/.
3. Open the command line terminal on the target machine and enter the directory where the pip source code is located. Use the following command to unzip the source code file:

tar -xzvf pip-<version>.tar.gz

Make sure to replace <version> with the version number of the pip source code you downloaded. After decompression is complete, enter the decompressed pip directory.

4. Enter the following command in the pip directory to install pip:

python setup.py install

After executing the above command, pip will be successfully installed on your machine.

Summary:
Without network, we can install pip through offline installation or manual installation. Offline installation requires downloading the pip installation package from a machine with network connection and copying it to the target machine for installation. Manual installation requires downloading the pip source code from a machine with a network connection, and decompressing and installing it on the target machine. Both of the above methods can successfully install pip without a network connection.

Note: When using these installation methods, we need to ensure that the pip installation package or source code downloaded is from a trustworthy website and is compatible with the operating system version of the target machine. In addition, errors related to dependent packages may occur during the installation process, and you may need to manually download and install these dependent packages.
