Total newbie here. Trying to setup my first arduino using IDE.
First of all I started on my PC. Couldn’t get IDE to run, it would crash at Loading Packages. Tried a few things I found on Google but couldn’t get it working at all.
Moved over to my Mac and got the app loaded, esp board added and created a test sketch using some code I found online. Tried to upload but I’m getting an error.
pyserial or esptool directories not found next to this upload.py
Again on Google, tried a few things but still doesn’t work even though those directories are in the same directory as upload.py.
Hopped back over to my PC and it seems since I tried a fix has come up for the issue I had so now I can load the app. Tried adding the esp board but when I go open board manager I just get two errors
Error downloading http://arduino.esp8266.com/stable/package_esp8266com_index.json
Error downloading https://downloads.arduino.cc/packages/package_index.json
Again, tried looking for some fixes for this but nothing I found works. 
I followed this guide to get it setup. Wemos D1 Mini Setup | Average Maker
Any help please?
