[Solved] Migrated App, Blynk won't compile

I migrated a long existing app of mine that includes Blynk and now it won’t compile using the web IDE. I’ve tried to remove it and re-add it but I get the same error:

lib/blynk/src/utility/BlynkDebug.cpp:9:30: fatal error: Blynk/BlynkDebug.h: No such file or directory
 #include <Blynk/BlynkDebug.h>
compilation terminated.
make[1]: *** [../build/target/user/platform-6lib/blynk/src/utility/BlynkDebug.o] Error 1
make: *** [user] Error 2

I even tried making a blank app with just blynk and the same thing happens.

// This #include statement was automatically added by the Particle IDE.
#include <blynk.h>

void setup() {


void loop() {


What am I missing?

Thanks for any help.

Make sure you use a recent version of system firmware (>=0.5.3)

I’m an idiot. Yup, Just had to up the dropdown to 0.6.0.


Actually 0.6.2 would be better - there were many fixes and enhancments since 0.6.0
