Allow user to define temp directory location

• Pip version: 9.0.1
• Python version: 3.5
• Operating system: Trisquel

Description:

I have two partitions in the Linux box. One with 20 GB (partition 1) where OS runs and data are stored in other partition with 250+ GB space (partition 2).

The partition 1 always has less than 1 GB of space after prolonged use of the machine and so far no other program has complained about the lack of space.

When I run pip I specify an option for cache-dir in the partition 2. Unfortunately, pip creates temp directory in /tmp directory. This creates problem while installing large set of packages like tensorflow. Specifying target option isn’t helpful. Here is the code which creates temp directory.

    if options.target_dir:
            options.ignore_installed = True
            temp_target_dir = tempfile.mkdtemp()
            options.target_dir = os.path.abspath(options.target_dir)
            if (os.path.exists(options.target_dir) and not
                    os.path.isdir(options.target_dir)):
                raise CommandError(
                    "Target path exists but is not a directory, will not "
                    "continue."
                )
            install_options.append('--home=' + temp_target_dir)

One option is to use dir option while creating the directory.

• Does it make sense to call tempfile.mkdtemp( dir=options.target_dir)?
• Does it make sense to get the tmp directory from user?

AIUI pip should respect the standard TMPDIR environment variable. Does that work for you?
