Can't be installed successfully

[lukeweston]

Arduino IDE Version: 1.8.5
Mac OSX 10.12.6
Python: 2.7.10
Which ESP8266 hardware I'm using is irrelevant, I'm not really up to that point.
I've shown the specific git clone path and board manager JSON file URL, below.

I have inserted the following entry into the additional board manager URLs:
http://arduino.esp8266.com/stable/package_esp8266com_index.json
The ESP8266 entry is now visible for installation in the Board Manager GUI.
I've attempted to install, with v 2.4.1 selected. (Selecting 2.4.0 does not fix the issue.)

Installation fails with the following error message in red text:
Error downloading https://github.com/esp8266/Arduino/releases/download/2.4.1/esp8266-2.4.1.zip

OK, that doesn't work, so let's try manually installing it.
I don't mind manual installation, as long as it gets the job done in a usable way.
(Remember this is OSX, so we're inside /Applications/Arduino.app/)
cd /Applications/Arduino.app/Contents/Java
cd hardware
mkdir esp8266com
cd esp8266com
git clone https://github.com/esp8266/Arduino.git esp8266
cd esp8266/tools
So far so good.

get.py fails. I'm not sure what Python packages etc, if any, are prerequisites for this script. No such requirements, beyond Python 2.7 itself, are documented on the documentation page.

Python is installed. (2.7.10)

I have followed the instructions as they are given on the documentation page, for both the manual install-from-git and the Board Manager cases, and in neither case can I get a successful installation.

$ python get.py

Hello @lukeweston ,
I have also a Mac but with Mac OS X 10.13.4 and here works the installation via board manager.

My python version is 2.7.15.

Thanks to clarify the manual installation method. I tried it to start in the ~/Library/Arduino15/ folder but this was not working.

Best Regards
Thomas

Just because I did it that way, don't assume that it's correct or the best way to do it :)

It seems that python 2.7.14 solves the import thing.

After upgrading to python 2.7.14, I still get a failure, a different failure, of that download script.

These errors seem to be completely SSL cert related (as if your specific system doesn't trust the CA that GitHub (now MSFT, I guess, so may be different from before) is using. I've even tried building the very old Python 2.7.14 and am presently able to run the get.py without any errors at all.

Closing as wontfix since there's nothing we can do on our end.
