Fatel Error: Metro.h: No such file or directory

[hb5fa]

I got the Metro.h (No such file or directory error) when I first tried out ESPHelper basicUse project. Any idea if the custom Metro.h file should be included into the project?

[ItKindaWorks]

Have you installed the Metro library from here?

[hb5fa]

Yes I did. Now I am getting ESP8266mDNS.h error. I do have pubsubclient library installed.

[ItKindaWorks]

Have you installed the ESP8266 core files from here?

[hb5fa]

Let me try. I didn't see it in your instruction.

[hb5fa]

Imported the library. Still getting the same error. Let me try something different.

[hb5fa]

Giving up! It forces me to use Teensy board. Once I switched back to generic ESP8266 board, the same Metro.h missing error again.

[ItKindaWorks]

Where do you have the metro library installed? Is it in your libraries folder inside of your sketch folder? The Metro library shouldn't be only usable with teensy.

I used the installer. I followed the instruction and installed in under the Arduino's un-zipped directory.

Download this and install the library into your Arduino sketches/libraries folder. Here is a guide on installing libraries manually https://www.arduino.cc/en/guide/libraries

Let me try

Specified folder/zip file does not contain a valid library Specified folder/zip file does not contain a valid library

That's when I tried to import the library as ZIP file.

[hb5fa]

Trying Manually now.

[ItKindaWorks]

unzip the folder and read the INSTALL.txt file within.

[hb5fa]

Ok. Trying...

[hb5fa]

Looks like it's going now!!! Thanks so much! I can upload the initial sketch now. I'll try the functionalities.

Great to hear you got it working!
