板级支持包安装不成功方法集

This workaround worked for me. Though the URL was returning expected JSON it was returning error "Error downloading http://arduino.esp8266.com/stable/package_esp8266com_index.json" in IDE. I tried following and now I'm able to resolve this issue.

1. Open preferences.txt from C:\Users\AppData\Local\Arduino15 ( this path may vary depending on your
OS) and remove value for "boardsmanager.additional.urls"
2. Delete all .tmp files from this folder (C:\Users\AppData\Local\Arduino15)
3. Copy & paste URL in File->preferences
4. Goto Board-> Manager board... now you dont see any error and ESP8266 should be there in the list
