Update the minimum system requirements

[pombredanne]

https://scancode-toolkit.readthedocs.io/en/latest/getting-started/install.html?highlight=RAM#system-requirements documents the minimum requirements ...

Hardware : ScanCode will run best with a modern X86 processor and at least 4GB of RAM and 500MB of disk. These are bare minimum requirements.
Supported operating systems: ScanCode should run on these 64-bit OSes running X86_64 processors:
Linux: on recent 64-bit Linux distributions,
Mac: on recent 64-bit macOS (10.14 and up),
Windows: on Windows 10 and up,
FreeBSD,

4GB and 500MB is on the low end and we want a 64 bits processor. We may run OK on Apple ARM M1 too though this is not tested and likely requires the x86 emulation mode.

To do this correctly, the following should be done:

• Run tests on multiple machines using the release archive. This can be done using a GH action or azure free. Collect the installed size on disk and get some memory info when running a simple scan.

Testing on M1 here. Wasn't able to build from a git clone. Let me know if I should create a separate issue.

ERROR: Cannot install extractcode[full]==21.7.23 because these package versions have conflicting dependencies.

The conflict is caused by:
    extractcode[full] 21.7.23 depends on extractcode-libarchive>=3.5.1.210525; extra == "full"
    The user requested (constraint) extractcode-libarchive==3.5.1.210531

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

@jroes Thank you ++ this helps!

I am working on a fix for this.

See also these:

• Revamp ScanCode installation packages #2836
• Build better wheels with improved compatibility skeleton#53
• and the many issues listed https://github.com/nexB/scancode-toolkit/issues?q=is%3Aopen+is%3Aissue+label%3A"installation+and+packaging"+label%3A"os+support"

We may run OK on Apple ARM M1 too though this is not tested and likely requires the x86 emulation mode.

For me, running ScanCode on my M1 Mac fails using x86_64 bash and python3.8:

I'm also trying to install on m1 mac, but I get the same error as #2835 (comment). (m1, python 3.9)

[pombredanne]

@soimkim @MarcelBochtler Thank you for the reports. I now officially hate Apple and ARM. 👼

@nsoft Thanks. The latest 31.* release candidate tarball should work on macOS with an M1 chip. The trick is that it requires to run in x86 emulation mode (aka. "Rosetta")... The installation/setup script in the release tarball handles this. See https://github.com/nexB/scancode-toolkit/blob/746c33683225efe16cf6630753b51ef7697574bb/scancode#L123

Alternatively you can force this mode on older versions by running first arch -x86_64 /bin/bash and then running configure or scancode proper!
