I want to install PlatformIO on my general MCU build machine, which is a Raspberry Pi 2 B+, but it does not have good Internet access (at least for now). It is on my workbench at my house and the only Internet access is via Dialup (yes, really!). What I would like to do is take my laptop (which runs CentOS 6, but has too old a version of python, glibc, etc.) to the local library and download a collection of tarballs or zip files and then unpack them on the 'Pi. Is this possible? I am pretty sure than using pip install or platformio install is not going to work very well (or just take forever and may crash when my dialup connect craps out, which is likely to do).
