SimpleTimer.h does not work in Audrino IDE upload to nodeMCU

[gedeyenite]

Upfront: I am a complete noob trying to figure out how to do this on the fly.

It appears that the SimpleTimer code no longer works. I tried replacing the path with other simpletimer URLs from github but they all produce the same error.

I copied the code for programming the nodeMCU, but it returns this error:

exit status 1

Compilation error: SimpleTimer.h: No such file or directory

Same. I get this error:

Error: 13 INTERNAL: Library install failed: moving extracted archive to destination dir: library not valid

This suggests that the code is not valid for Arduino?
