How do I suppress the warning "unable to find the application log" after running "symfony serve"?

Question

With Symfony 4.3 and Symfony CLI v4.7.1, when I run:

symfony serve

I see the following warning in the output:

WARNING unable to find the application log

How do I solve the issue that raises this warning? Do I have to install the logger bundle?

Answer 1

I have bumped into the same issue today. For some reason, I had to create an empty log file (dev.log) inside the var/log directory. After that, the warning disappeared and the log messages appeared in the file.

Answer 2

You have to install the "logger" package:

composer require logger
