pm2 logs do not print realtime on M2 Pro
Hi. I am a M2 Pro user who want to use pm2. But PM2 does not output logs in real-time on M2 Pro.
With PM2 on M2 Pro, logs are not displayed or printed in real-time, and when PM2 is killed or updated, all logs are recorded or saved to the logs file. When run with Node.js, logs within asynchronous functions are displayed in real-time. Even when running a Python file with a while loop, logs are displayed properly. However, when executed with PM2, logs are not displayed in real-time.
Here is the example logs when running Python code with pm2. The timestamp in front of the 'Loop....' message is the time displayed by the '--time' command in PM2, and the timestamp after the 'Loop....' message is the actual time when the print function is executed in Python. "Loop...." is outputted every minute.
