ERROR: setup() missing 1 required positional argument: 'iothub_connection_string' when running iotedgedev start

• iotedgedev Version:1.3.0
• Python Version: 3.6.7
• Pip Version:19.1
• Development machine OS Version: Window Version 10.0.17134 Build 17134
• IoT Edge device OS Version:Linux 3d5513d56f80 4.9.125-linuxkit Explain .env file for a 5th grader #1 SMP Fri Sep 7 08:20:28 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

Steps to Reproduce:

1. Follow the instructions in the quickstart guide https://github.com/Azure/iotedgedev/wiki/quickstart-with-iot-edge-dev-container
2. manually edit the file sudo nano /usr/local/lib/python3.6/dist-packages/iotedgedev/azurecli.py to access key "connectionString" instead of "cs"
3. at step 5 of the quickstart guide, run sudo iotedgedev start --setup --file config/deployment.amd64.json

the command constantly shows the following output:

iotedgedev@3d5513d56f80:/home/iotedge$ sudo iotedgedev start --setup --file config/deployment.amd64.json

ERROR: setup() missing 1 required positional argument: 'iothub_connection_string'

checking the .env file i see that both connection strings are properly set (IOTHUB_CONNECTION_STRING and DEVICE_CONNECTION_STRING).

so i'm a bit lost here. is there another script incompatibility similar to the one with the "cs" parameter ?

Holy XXX, in my desperation i was running a

sudo iotedgedev setup

and this fixed it for me.

the following call to sudo iotedgedev start succeeded.

This should definitely be mentioned in the "Quickstart" IMHO.
