I was using examples from the esp8266 weather station lib for quite some time on the Heltec wifi kit. Thanks for that great work 
But I run into problems after updating Arduino 1.8.12 on MacOs 10.14.6. So i had to downgrade it to 1.8.8. but ever since it throws me out errors during compile.
Not sure if I did something wrong during the downgrade but other projects run fine atm. Probably it's just a path or include issue, but i'm no pro. I deleted the lib, reinstalled 2.0.1 without change. now on 1.6.3...
Here's the error log:
