为什么 pm2 可以，但 pm2 日志不行？

Question

I'm using pm2 to keep tracking of what I do on backend with NodeJS. Until yesterday it all worked perfectly fine, but today, even if pm2 server is working fine (i can start the project server and i can navigate), pm2 logs just stopped for no reasons.

Here you can see the version I'm using (i already updated PM2 both on project and local as i find in other answers).
I usually use the command

pm2 start process.json
pm2 restart 0 --watch
pm2 restart 0

And in other prompt instance, for the logs i use

pm2 logs

For some reason PM2 is just tailgating the last 15 lines but it doesn't work real time like it used to do

I didn't find this exact problem on other questions (only questions about pm2 not working at all, but not about pm2 working half way). Any suggestions?

Answer 1

Apparently the version of node and pm2 were the source of the problem. I used this command to run pm2 using the node version explicitly

pm2 start process.json --interpreter=/home/ken/.nvm/v10.15.1/bin/node

This way you force pm2 to use settings for the version of node you've installed in your machine. Now both server and logs works fine.
