为什么我在连接 Firebase 时遇到 Arduino 中的这个问题？

Question

Arduino: 1.8.13 (Windows 10), Board: "NodeMCU 1.0 (ESP-12E Module), 80 MHz, Flash, Disabled (new aborts on oom), Disabled, All SSL ciphers (most compatible), 32KB cache + 32KB IRAM (balanced), Use pgm_read macros for IRAM/PROGMEM, 4MB (FS:2MB OTA:~1019KB), 2, v2 Lower Memory, Disabled, None, Only Sketch, 115200"

exit status 1

Error compiling for board NodeMCU 1.0 (ESP-12E Module).



This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Answer 1

When I faced the same issue, I rolled back to 2.7.4 on the board manager, which result in it compiling without a problem. I guess the board software updated before the FireBase library did. I found this solution on this page .

Answer 2

I found out the mistakes as I was transferring the code from an old laptop to a new laptop.

Guess What? The version of Arduino library that i recently download in my new laptop does not match the version in the old laptop. That is why the error message had pop out.

Answer 3

with platformio, change in platformio.ini (work for me), for latest 2.x version:

platform = espressif8266@^2

Solution from this page

Answer 4

rolled back to 2.7.X version enter image description here
