Need help: got No such file or directory error for installed library

Hi guys, I am new to the Sparkfun and trying to learn. I have a SAMD21 mini breakout board and when I tried provided examples I got the library problems like i2cdetect:2:23: fatal error: i2cdetect.h: No such file or directory or realclock:1:21: fatal error: RTCZero.h: No such file or directory. I am pretty sure I installed these libraries.

No idea what happened, need help.

Thanks in advance.

Try uninstalling via these instructions https://support.arduino.cc/hc/en-us/art … rduino-IDE and reinstalling via this guide https://learn.sparkfun.com/tutorials/sa … 1653495744

Thanks very much. I finally figured out the issue. When I install libraries, they are installed into a different folder, I moved them to the path where I installed Arduino and the problem was solved.
