It's my first experience with platformio and with the esp8266 so I am very new to it. When I try to run a platformio run, I got this issue.

Installing the library doesn't sound to help.

ludo@idefix:~/repos/esp8266-dht22-sensor % platformio lib install "DHT22"

The project works as is, but you need to manually install the right DHT library. I installed this one in the .platformio/lib folder and then it build just fine: https://github.com/adafruit/DHT-sensor-library
