    The syntax differs for pip install. You have to use "pip install requests==2.28.0"

    You need to check whether the machine has outbound access. 
    Try pinging pypi.org

    The machine does not have access to the internet.
    Can I download the requirements, and keep them locally.

    From an Internet-connected host, you can do something like:

    python3 -m pip download \
      --dest=my-download-directory \
      --no-binary=:all: \
      requests==2.28.0

    This will download the source packages for the modules to my-download-directory. You will still need to install any libraries that the Python modules need in order to to be built. It is possible to download wheel files, but it's more complicated if you're not on the same OS and architecture as the target system. Also, I'm not sure how complete the wheel coverage is for AIX...

    Copy the download directory to the target system.

    To install the modules, it's something like this:

    python3 -m pip install requests==2.28.0 \
                   --no-index \
                   --find-links my-download-directory

    These may not be exactly correct for you, but it's the method I use to download packages for linux-x86_64 on my macOS-arm64 system.

     If this is something that you're going to keep track of long-term, you probably want to create a requirements and/or constraints file for pip.
