Are you using this command to install the SDK?

curl -L hologram.io/python-install | bash
4

yes

5

Are you using Jessie or Stretch (Raspbian version)?

cat /etc/os-release

you can also this to manually install the version they are asking for:

pip2 install pyserial==3.3
6

says stretch i just down loaded the zip to a sdcard and ran the install

pyserial installed ok
still fails to install

i loaded form “Raspberry Pi OS – Raspberry Pi” is that not right?

7

I am also using stretch, just wanted to make sure our environments were the same. Will you post the result of the install command?

8

just installing again atm
then i have been running sudo apt-get install ppp
then curl -L hologram.io/python-install | bash

should i run something else besides update and upgrade be for curl…

9

Not that I can remember. I just grabbed a random pi that I was using as a camera monitor and ran the curl script and it installed. I will try a fresh one in a bit if we cant get you sorted out.

10

ok brand new sdcard with noods
did install
installed ppp
ran curl and here is the out put

Try this

Upgrade pip (may not be needed)
sudo pip2 install --upgrade pip

And then
sudo pip2 install pyserial==3.3 --ignore-installed

Then run the installer again
curl -L hologram.io/python-install | bash
